Cloud Computing

The traditional desktop system is where we run and save our software and other applications copies on our computer and these documents are stored on our PC. However, these documents and programs can be accessed by another computer which is under the same network; they can’t be accessed by computer outside the network.

With the use of cloud computing, the software programs which one uses are not run from one’s personal computer, but are rather stored on servers accessed via internet.

What is Cloud Computing?

In cloud computing, the word cloud is used as an icon for “the internet”. So cloud computing means “a type of internet-based computing”, where applications, software and programs are delivered to an organization’s computer and devices through the internet. Cloud computing is basically working on sharing of resources so that consistency or rationality can be achieved. It is like using of electricity, cloud computing is a utility over a network. Mainly cloud computing is the mediator which helps infrastructure and shared devices meet each other.

Having large corporation you may need to provide all your employees proper hardware and software devices so that they can perform their jobs. For each and every employee installing software for their computers is necessary, in cloud computing you only need to download one application. However, cloud computing would facilitate worker or users to log into different web-based services which host all the programs which users may need for his or her job. Here, your user’s machine can be called as a remote machine which runs everything from email, which makes work simpler from word processing to complex data analysis. This is called nothing but a cloud computing functioning.

Why Cloud Computing?

Mainly Cloud computing is user centric, Task centric, powerful, accessible, intelligent and programmable.

Architecture of Cloud:

In cloud computing, users connect to the cloud from their portable shared devices or own personal computers, over the internet. For these users cloud is seen like an application or device or document. In the architecture of cloud, the hardware devices mean the operating system that manages hardware connection which is invisible.

Moving to Cloud:

The term “moving to cloud”, refers that an organization moving from a traditional model of CAPEX which means moving from buying hardware and depreciate it over a period of time to the OPEX model means using shared cloud infrastructure and pay as one use it. Cloud providers mostly based on “pay as you go” means pay as per the use, but this can be a high on charges if administrator do not adapt to the cloud pricing model. In cloud computing, the high capacity network, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service –oriented architecture and autonomic and utility computing have led to a growth.

Cloud Storage

The term cloud storage means, “the storage of data online in cloud”, where company’s data is stored and accessible from multiple connected and distributed resources that comprise a cloud. The benefit of cloud storage is, it can provide greater accessibility and reliability, rapid deployment, strong protection for data backup.

Advantages of Cloud Computing:

There are various features that user will be able to track while using the Cloud computing system. Cloud computing system consists of,

  • Lower computer costs.
  • Reduced software cost.
  • Unlimited storage capacity.
  • Instant software updates.
  • Improved performance.
  • Increased data reliability.

Private Cloud

A virtual Private Cloud is a kind of infrastructure which shares one data centre of hardware and software. This data centre is most likely out of premises, which can be shared with multiple organizations. When the data centre is not shared then that is called or known as a Private Cloud.

Lorem A private cloud is a specific pattern or part of cloud computing, which majorly involves a separate and protected environment where only some specified or precise client can operate. Compare to other cloud models, private clouds can supply computing power as a part of service within a virtualized environment by using an underlying pool of physical computing resources. Under the private cloud model, the cloud can be accessible by a single organization, with a condition that organization have to consists great control and privacy policy.

Private cloud is very similar as public cloud which provides advantages similar to public cloud, which includes scalability and self –service, all the way through a proprietary architecture. Precisely private cloud is dedicated to a single organization, which provides service to one organization.

The services of private cloud which are classed under the term technical mechanism is considerably very different, so it is bit tricky or hard to define the technical feature of private cloud exactly. So, mostly these kinds of services are categorized by their features which are offered to their client. The most unique personality of private cloud is it includes the ring fencing of a cloud and the higher level of network security. Private cloud services gather their resources from a separate or divided pool of physical computers however it may be possible that these physical pools of computers can be hosted internally or externally and it might be accessed through private leased lines or secure encrypted connections by using public networks.

Private cloud is having a feature of ring fenced cloud model which offer additional security which is ideal for any organization, private cloud is ultimate for the enterprises which needs to accumulate and develops private data or perform sensitive tasks. A very quick example, a private cloud service could be used by a financial company which requires to store some sensitive data internally and which wants to get the advantages of cloud computing within the business infrastructure.

The private cloud model is very similar to the local access networks (LANs) which used in the past by many enterprises; however the private cloud is similar to LANs with the added advantages of virtualization.

The features and the benefits of Private Clouds are,

Higher ratio of security and privacy, the techniques used by private cloud such as distinct pools of resources with the restricted access connections created by one organization’s firewall, devoted leased lines can give assurance that operations of enterprises are kept out of the reach to the pry eyes.

More control, the private cloud is accessible by only one single organization, so the organizations have the ability to configure and manage it internally with their needs to achieve network solution, which generates the higher level of control over the security.

Cost efficiency, the private cloud model can help the organization to improve the allocation of resources with the assurance that the available resources can directly and flexibly respond the demand of individual department or business functions. Therefore, compare to public cloud private cloud is more cost effective due to smaller economies of scale; private cloud can make more efficient use of the computing resources than traditional LANs as private cloud minimize the investment cost.

Enhanced reliability, resources such as servers, networks etc. are hosted internally, the formation of virtualized operating environment means the network is more flexible compare to failure of physical infrastructure. For example, virtual partition which pulls their resources from the remaining affected server area. Additionally, when the cloud is hosted by third party, the organization can get the benefit of the physical security afforded by the infrastructure within data centre.

Cloud bursting, it may possible that some providers offer the opportunity to employ cloud bursting, within a set up of private cloud, while the spikes in demand. Mostly this service allows the provider to switch some functions to a public cloud so that organization can get some more free space in the private cloud for some sensitive functions which require performing by the organization. It is possible that Private cloud can be integrated with public cloud service through which organization can form the hybrid cloud where non-sensitive functions can allocate to public cloud so the organization can offer the maximize efficiency to private cloud.

Cloud Management

Cloud management refers to manage the products and services of cloud computing. Cloud management is systematic process to manage cloud settings and features with managing their related tasks.

Cloud management mainly include organizing, monitoring, analyzing of the data. Cloud features comprise with capacity, utilization, availability and more. The cloud management is nothing but a system management.

The first and most important task of cloud management is protecting data. Data management includes creating security for data it is not simple as it sounds as data is scattered throughout the organization. All the data of an organization is important no business can be function without any single data. Out of all the data, some data is required frequently for day to day operations where as some of them required immediate access so, while in cloud management it is extremely important to keep in mind about the accessibility of data.

In cloud management the amount of users changes all the time as per the enterprise regulation and need of service. These aspect changes the cloud environment. The operation investment and the ongoing charges are varies from each other; there is minor difference between both. The team who arrange the cloud can maintain the cloud operations continually. Data designing, cycle of learning and changes is the part of any cloud management policy.

Classifying and summery of the data can help an organization regarding which type of cloud implementation is best suitable so that while cloud management it will be easy task regarding securing of data. The cloud management market is unstable and the related technical terminology is fluctuating.

The cloud management software can help to manage all elements of cloud computing, physical and virtual resources. It allows the traditional hardware foundation turn into a cloud platform by mechanizing and streamlining the operation by managing resources properly and appropriately. By applying this way, organization can get the most from their investment and develop the new growth opportunities of cloud services.

Features of Cloud Management

Cloud management process system is merging the software and technologies in a way or design to manage cloud environment. Software developers have to take an action to manage the challenges of cloud computing with cloud management system.

Cloud management system should have the capability to,

- Provide access to users.

- Continuous monitoring for data security.

- Management for the resource allocation.

- Manage the path of data process throughout the enterprise.

- Managing the team connectivity with various compute- resources.

For amalgamated application, cloud management system also includes work flow mapping and management.

For cloud implementation a large enterprises require more healthy and forceful cloud management tools which must be having specific characteristics like, ability to manage multiple programs from a single intelligent analytics to mechanize processes like application lifecycle management.

An effective and high end efficiency cloud management should consist tools such as, ability to handle system failure automatically with self-monitoring, an explicit notification mechanism and include failover with self healing capabilities.

Manage Risk

Almost every organization or enterprise is using cloud computing in some way or form. Cloud computing is fast growing technology, majority of organizations are applying it in their business. Giving all the information and educating your employees regarding the technology and its associated risks and benefits is most important. While looking at the outlook opportunities presented by cloud computing, creating security of your sensitive data is the most important task of managing risk, while exploring cloud computing vendor management.

Risk management required three main steps, (1) IT security Risk Assessment (2) Monitoring of IT Security Risk (3) Risk Communication of IT Security. Throughout the different years, eras in history of cloud computing the number of different tools have been developed to manage the risk. The most significant purpose of IT Security Risk management is to find out the acceptable risk level of the organization and if needed installing new countermeasures to reach that level. The core step of Monitoring of IT security Risk is to react on new threats and incidents. IT Security Risk Communication is the communication between different levels of organization, if needed organization make necessary changes so the organization have proper documentation, communicated and monitoring the period of escalation. This is very essential for the cloud computing environment where resources and data are shared between users of cloud customers.

“The Cloud” is a grand large scale term of information technology computing environment where individuals or employers and businesses work with applications and data which are stored and maintained in a web-based environment, rather than physically located in a user’s location.

Service models of Cloud computing:-

IaaS : Infrastructure as a Service
This most basic cloud-service model enables access to server hardware, storage network capacity, and other basic computing resources.

PaaS : Platform as a ServiceIn this model, cloud providers deliver a computing platform normally including operating system, programming language execution environment, and database and web server. PaaS enables access to basic operating software and services to develop and use customer –created software application.

SaaS : Software as a Service
It is a service-on-demand cloud computing type where a provider will license software tailored. In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. With SaaS software service Management of cloud infrastructure and platform where the application runs can eliminate. The best feature of this software is it eliminates the requirement to install and run the application on the cloud user’s own computers, which makes easy maintenance and support.

The Risk Management:-

Environmental Security in the cloud computing environment represents the concentration of security threats. Due to their size and consequence, cloud environment are often targeted by virtual machines and bot malware, brute force attacks and other attacks. Organization must need to get the access controls from the cloud provider, and the configuration management needs to controls to see that they are effectively protecting data.

Data security and privacy of data cloud service providers host the confidential data which involves the transfer of significant amount of an organization’s control over the data security to the provider. Organization must provide all the understanding of data privacy and security to vendor of cloud computing. Organization must have to check the awareness of the cloud provider regarding data security and privacy rules.

Availability of data and business continuity in the cloud computing, a major risk to business continuity is loss of internet connectivity. Ask the significant help to cloud provider which ensures internet connectivity. If any kind of susceptibility is defined, organization may terminate all access to the cloud provider till the susceptibility is rectified.

Disaster Recovery cloud providers do host the organization’s computing resources so that cloud providers need to make the disaster recovery capabilities vitally important to company’s disaster recovery plans. Organization need to know the cloud provider’s recovery capabilities and also make sure that they have been tested.

When organizations use the cloud, probably organization doesn’t have any idea where their data is hosted. Many times it happens that organization don’t know in which country the data will supposed to be stored. So in this case organization may need to ask providers regarding the contractual commitment to obey local privacy requirement on behalf of organization.

Cloud provider should explain organization about what will happen to data and service in case of disaster. Organization also needs to ask to cloud provider the time period in which the provider can restore the data again.

In cloud computing organization relies on the cloud provider as the custodian of their data, organization must demand the cloud computing agreement which explicitly contains, provider’s responsibility to back up the data and regulatory of that back up, the customer’s access to data on regular basis.

These days’ businesses are rushing to the cloud. There is a substantial risk that comes with a cloud computing solutions. Traditional IT technology consist software licenses and hardware agreements whereas in cloud computing with service provider agreements enterprises also needs to focus on less configuration, implementation and acceptance and more on service availability.


It is an endeavor of IT sector to encourage IT directors to invest in vast and expensive computer organism to develop and make it more progressive the flow of knowledge through their organizations, as per the leading expert there are other way to make information flow more impressive.

Creating socializing easy for employees is one of the excellent and best investments so that a company can create knowledge sharing in best way.

There are six broad approaches which companies require to make most of it, capture and use of knowledge in an organization,

Need to codify and validate the knowledge that a company has already got it, for example creating a proper setting of an intranet bulletin board to codify best practice.

One of the most important and effective is, constructing or creating directories of company’ s expert people by mentioning their knowledge expertise areas and also need to explain about how to find them.

Providing knowledge expertise subjects with deep descriptions to people and employees with the expectation that some data will be useful and used.

Building a network to facilitate the knowledge by intermediaries, by creating practice, discussion and task-oriented moderated group.

Creating physical space to make knowledge flow, maximize potential for physical meeting.

Two different business standards and principals are emerging to handle the tension between two participants and to create the corporate control over data.

It’s been a long time SharePoint is the leader in the document and content sharing, however it is admittedly weak on the social media. Some numbers of companies from the third- party aspect are trying to fill the gaps between the portal’s strong point and shortcomings with infusions of popular functions.

Jive software successfully creates the belief that their Social Business Suits (SBS) which first released as a “Clearspace” in 2006 is one of the greatest thing to happen to the enterprise. Jive has become the leader in Social business software in last couple of years,

Jive’s Web Parts facilitate SharePoint users to integrate the platform, merging workflows completely.

Key Features of SharePoint:

All the SharePoint files can automatically shared with Jive software.

Activities of SharePoint such as new docs, file update, calendar views, project lists etc displayed in the Jive environment.

One time single sign-on facilitates users to study and analyses SharePoint documents from Jive without logging into SharePoint.

With just one time click all the content can be pushed from one platform to other.

From one location users can explore all discussions, documents and experts.

Amalgamation of Jive and SharePoint

Blank-slate approach is the key due to which SharePoint is successful. The focus is on the engagement side of things rather than on document management.

The director of Jive product has said that the whole focus of Jive is on the strategy to design the best platform around engaging people and not just on documentation.

Features of SharePoint:

Information exchange: update of status can be explained with more than 140 characters and can also contain relevant videos, links, business files and images.

Search: SharePoint can be merged with social sites so it includes fast searching, through the use of BCS (business connectivity services).

Access: it makes easier for business to use social business clients, including email, mobile and desktop – for easy updating and consuming of status updates, comments and likes.

Administer: the administrative social software tools put the control in hands of enterprise. Users can get the capacity to delete any inappropriate updates and comments.

In March 2013 Microsoft announced the general release of SharePoint. Among all the existing feature Microsoft announced the new feature packed which boost to social element with the inclusion of “Enterprise Social Network “Yammer”

A few key features of Yammer and SharePoint integration:

Successful purchase of Microsoft fast tracked the integration of yammer into the SharePoint it boosts its existing social features.

Yammer allows feed, private messages and notifications straight into SharePoint allowing team and company-wide conversation.

Inserting Yammer into SharePoint will keeps an eye on relevant discussion occurring in the workplace.

It helps to create links to resources within SharePoint including documents, tasks and calendar events in real time via yammer will feeds instant collaboration.

Yammer can avoid duplication of profile creation by importing SharePoint profiles straight to Yammer.

Yammer notification can be track straight from the sharePoint top banner.

Disaster Recovery

These days cloud computing is attracting many business enterprises and organizations. The reason behind adopting cloud computing is its simplicity, easy deployment, cost effectiveness and the most unique feature is its flexibility. Many business and organizations use cloud computing may experience disaster by nature or sometime manmade which results in loss of data. The most important advantage of cloud computing is its approach to recovery plan in timing of crisis when data can be lost.

When disaster occurs we can apply and use recovery skills to have back up of data. Sometime there are difficulties like time complication, cost efficiency which makes user very difficult to handle disaster. By applying disaster recovery as a service enterprise can handle the timing of disasters and can recover data fast with low cost.

Cloud computing offers completely different approach and outlook to disaster recovery. According to this approach, the operating system, data and applications are integrated with each other into a single software virtual server. The beauty of this server is, with this server data can be easily copied and can have back up offsite data centre within minutes. This disaster recovery approach is extremely beneficial as it is hardware independent so business enterprise can transfer data from one data centre to another without installing any component of server. In comparison of traditional disaster recovery approach cloud based data disaster approach is highly cost effective and it reduces recovery time.

Providing all employees licensed software and handling these software and devices is not an easy task, cloud computing can help to overcome this problem. Basically cloud computing is internet based computing system in which systems are interconnected with sharing resources by each other. Internet is the medium between cloud and user. Cloud is having many servers of application, platform and infrastructure. In cloud computing client is connected to cloud server and can store and access the data from anywhere through internet. One can run programs from anywhere by accessing cloud. To access the software or any data one does not need to pay any amount to cloud.

Sometime powerful power failure or system crashes may construct chances for loss of data which can result in financial loss as well. The reason behind system crashing and other problem occurs due to natural disasters or by human errors as well. This may result into a big financial loss with loss of data. This incident can cause damage to life, property and destroy the economic and social personality of business organization. Cloud providing companies like Bitscape technology a Microsoft partner can help enterprise with cloud disaster recovery plan to get the data back in the time of disaster.

Reasons for Data Loss

Natural Disaster: due to natural disaster some percentage of data can be lost. The main reasons for the natural disaster are mostly unpredictable, sudden occurrence.

Application failure: some applications which are left unusable for some period of time or for few days then it causes a catastrophic failure in some organization which may create a situation for data loss.

Failure in Network: cloud computing is purely based on internet. Cloud and clients are connected by internet and the moment network fails the system which are connected to cloud are crashed and data will be lost and applications which are working on cloud will also suffer.

Disturbance in Network: when a virus is attack on the applications then there is a major chance of occurrence of disaster. By placing unusable application on that place and keep a watch on that we can prevent the disaster.

Hacking or malicious code: disaster occurs in inside or outside of the organization due to hacking or malicious code with intention of data capturing.

System failure: when the infrastructure of an organization fails then whole systems which are connected will crash and this will affect the operating system.

The major reason for occurrence of disaster is human and then failure of data centre.

Easy deployment and cost effectiveness, there are some other benefits of cloud-based disaster recovery approach,

The cloud policy manages the disaster recovery server and devices which are used for storage effectively and decreases the collision of failure at the disaster site.

Applying cloud it is possible to add more resources whenever needed with optimum costs.

The most unique part of cloud based approach is it completely eliminates the hardware dependencies and also reduces the hardware backup cost.

It is easily automated with low recovery times after disaster.

Cloud computing is based on virtualization which is having very different approach to disaster recovery. With the virtualization, the whole server which contains operating system, applications, patches and data is summarized into a single software or virtual server. This whole entire virtual server can be backed up or copied to an offsite data centre and sum up whole data on a virtual host in a minute.

The virtual system is independent from hardware, the applications, operating system and data can be safely and completely transferred from one data centre to another data centre. As the cloud system is virtualized it reduces the recovery times.

Storage and Backup

Cloud Storage

For Some organizations, it’s a real challenge to find enough storage space to save all the data they acquired. Some organizations invest in larger hard drives, some prefer to use thumb drivers or compact discs. Some manage their data in order to make space for new data by deleting older data so that they can make space for newer data, however some are choosing and relying on growing trends: Cloud Storage.

Cloud storage is a service model where data is saved, maintained, managed and backed up remotely and provide to users when it is required over a network or internet. Cloud storage refers to saving data to internet which is maintained by third party or cloud provider. Storing data to computer instead of that, data can be stored over an internet with cloud.

There are several advantages of cloud storage compare to traditional data storage system. For example, if one stores all the data with cloud storage system then one can access the data from any location with internet access. Sharing the data with other people is also easy with cloud storage.

The literal meaning of cloud storage is, “storing and saving the data online in the cloud”. With the cloud storage company’s data is stored and accessible from multiple users who are connected through a cloud.

There are various types of cloud storage systems available. Some are having a specific focus, such as storing email messages, digital pictures etc. Some cloud storage systems are having small operations while some are having large data operations. The facilities of cloud storage systems are called data centers.

Types of Cloud Storage

Public Cloud storage is a cloud where the organization and storage service provider both are separate and there are not any cloud resources stored in the organization’s data centre. Organization’s cloud storage is completely managed by the cloud storage service provider.

A private cloud storage service is dedicated on providing an environment to protect data behind an organization’s firewall. Private cloud storage is ideal for those enterprises that need to customize their data over their control.

Hybrid Cloud Storage is amalgamation of public and private cloud storage where some critical and confidential data saved in the enterprise’s private cloud while other data is stored and shared with people from public cloud storage provider.

Some specific benefits of using cloud storage,

Most notable benefit is accessibility of data files. Files saved in the cloud can be easily accessed at anytime from any place with just having internet access.

Cloud storage facilitates organization with remote access of data which reduces the costs of data recovery at the time of disaster.

Some drawbacks of using cloud storage,

The biggest drawback of cloud storage is internet speed, if users are having limited bandwidth, if internet connection is slow or unstable then there might have problems in accessing or sharing data files.

The cloud storage service provider needs to create backups of data. If something happens with the client’s computer system then the data must be survive off-site with the provider and need to make it available to client. It’s like,” don’t keep all eggs in one basket”.


Cloud backup or cloud computer backup is also acknowledged as online data backup. Cloud backup contain taking backup of data from cloud storage to cloud based server. The data is stored under the cloud storage and cloud backup is process of taking backup of stored data and make accessible to several distributed and connected resources that comprise a cloud.

Cloud backup mainly facilitate organization or individual to store their data and computer files on the internet space using storage service provider which is called cloud storage rather than storing data on disk such as hard disk or hard drive.

Cloud backup provider enables enterprise to remotely access the service of cloud using a secure unique log in application to back up files from the user’s computers or data centre to online storage.

Cloud backup is a strategy which involves sending a copy of the data over a public network to an off-site server. This server is managed and hosted by third party service provider, whose charges are based on capacity of storage, bandwidth or number of users.

Online cloud backup system are mainly design around client’s software application which runs as per the schedule determined by the level of service the customer has purchased. If the customer has contract for daily backup then the service provider’s server must collect the applications, compresses, encrypts and transfer the data every 24 hours.

Restore a Cloud Backup

It is necessary to update or restore a cloud backup for which customer need to use the service provider’s specific client application or web browser interface. Data and files can be automatically saved to the cloud backup service regularly or as per the schedule.

Enterprise Grade Cloud Backup

For different enterprises, the cloud backup solutions are available with essential features such as archiving and disaster recovery. The archiving feature would help the enterprise with legal requirement for data retention, and it ensures that the data is safe from flood, hackers attack or employee theft as per the company’s disaster recovery plan.

Offered Services

Cloud computing is itself a very broad term which consists broad range of services. With significant major developments in information technology, several dealers have seized the term “cloud” which is used for products that sit outside the common definition. To understand the true value of Cloud for an organization, it is most important to understand what cloud is really and the various components of cloud. As cloud is having a broad collection of services, first organizations need to choose where, when and how they use cloud computing.

IaaS | Infrastructure as a Service

Infrastructure as a Service (IaaS) is the software and hardware that powers it all – servers, storage, networks operating system.

In an organization IaaS allows to run whole data centre application stacks, from the operating system up to the application, on a service provider’s infrastructure. It abstracts hardware which includes server, storage and network infrastructure into a collection of computing, storage and connectivity capabilities which deliver as services for a usage based cost.

It has been seen that IaaS usually provide a standardized virtual server. The customer or buyer takes an opportunity for configuration and operations of the guest Operating System (OS), software and Database (DB). Compute capabilities like performance, bandwidth and storage access are also standardized.

Characteristics of IaaS

- Resources are distributed as a service.

- It permits for dynamic scaling

- IaaS is having variable cost, utility pricing model.

- Mostly it includes multiple users on a single piece of hardware.

Some of the examples of how IaaS can be utilized by enterprise,

Cloud Hosting: the website hosting on virtual server which are found upon pooled resources from physical server. A website which hosted under cloud can be benefited from the redundancy provided by a vast network of physical servers and on demand scalability to deal with unexpected demands placed on website.

Enterprise Infrastructure: with internal business networks like private clouds and virtual local area networks which utilize networking server and in which business can store all the data and run the applications which they need to operate for day-to day operations.

Virtual Data Centers (VDC): virtualized network of interconnected virtual servers which can be used to offer an enhanced cloud hosting capabilities, enterprise IT infrastructure or to integrate all of these operations within private or public cloud implementation.

There are some situations where IaaS makes sense which are closely related to the benefits which cloud computing brings. Situations which are particularly suitable for cloud infrastructure,

Where demand is very unpredictable – at any moment of time there considerable spikes and troughs terms demands in infrastructure.

For those organization which are new and not having capital to invest in hardware.

The organization which is growing speedy and scale hardware would be problematic.

An organization which are having pressure to limit capital expenditure and to move to operating expenditure.

PaaS | Platform as a Service

Platform as a Service (PaaS) is the compiled set of tools and services designed to make coding and deploying those applications quick and efficient.

PaaS can provide a platform on which a customer can run its own applications. It brings application execution services, like application runtime, storage and integration, for applications which are written for a pre-specified development framework. PaaS offers an efficient and responsive approach to operate scale – out applications in a predictable and cost-effective manner. The risk of operations and service levels are shared as the buyer must take responsibility for the stability, architectural compliance and overall operations of the application while the provider delivers the platform capability at a conventional service level and cost.

Platform as a Service (PaaS) brings the benefits which are same as SaaS bought for applications, however over to the software development world. PaaS can be classify as computing platform which permits the creations of web applications quickly and easily without the intricacy of buying and maintaining the software and infrastructure underneath it.

PaaS is mostly equivalent to SaaS apart from that, rather than being software delivered over the web, it is a platform for the creation of software, delivered over the web.

Characteristics of PaaS

Service to develop analysis, deploy, host and maintain applications in the same integrated development environment. All the unstable services needed to fulfill the application development process.

Web based client interface creation tools help to create, modify, test and deploy different UI scenarios.

Multi- tenant architecture in which multiple concurrent users develop the same development application.

Built in scalability of deployed software including load balancing and failover.

Amalgamation with web services and databases via common standards.

Assisting help and support for development team assistance – some PaaS solutions which consist project planning and communication tools.

Tools to manage billing and subscription management.

There are some ways in which PaaS and IaaS are similar; the similarities are as below,

A shared platform for software development, focused on workflow management despite of the data source being used for the application.

A platform which allows for the formation of software utilizing proprietary data from an application. This kind of PaaS can be seen as a method to create applications with a common data form or type.

Situation where PaaS make sense:

PaaS is valuably useful in any situation where several developers will be working on a same development project or where the external person who wants to interact with the development team regarding the development process.

SaaS | Software as a Service

Software as a Service (SaaS) this application is designed for end-users, delivered over the web.

SaaS is speedily growing in market as per the recent report. Mainly Software as a Service (SaaS) brings business processes and applications such as CRM, collaboration and e-mail with standardized potentials for a usage-based cost at an agreed, business relevant service level. SaaS offers considerable efficiencies in price or cost and delivery in exchange for minimal customization and stand for a shift of operational risks from the consumer to the provider. The consumer is away from all infrastructure and IT operational functions.

Software as a Service is classify as, Software that is deploy over the internet.

With SaaS, a customer can get license an application either as a service on demand, through a subscription, on payment based means “pay as you go” model or there may be no charge if the opportunity is to generate revenue from streams other than the user, like in form of advertisement.

The fast growing SaaS shows that it will be soon become usual place within every enterprise and therefore it is very necessary for buyers and users of technology to understand what SaaS is and where it is suitable.

Characteristics of SaaS

Easy web access to commercial software.

The software is managed through a central location.

Software distributed in a “one to many” model.

Users need not to require software updates and patches.

APIs which show for Application Programming Interface allow for integration between different pieces of software.

Situation where SaaS make sense:

In cloud computing SaaS is fast growing method of technology. Organizations which consider moving to the cloud will want to consider which SaaS application they want move.

There is specific interplay between the organization and the outside world by the applications. Such as, email, newsletter campaign software.

Application which has a specific requirement for web or mobile access. Such as mobiles sales management software.

Software which are only used for short term need. Collaboration software for a specific project is the best example.
