Cloud computing refers to as a system where services are rendered to the clients on demand, through the Cloud. It is an internet based model wherein services are provided to the consumer’s computer on demand.

Cloud computing has come forward from being an idealistic concept to emerge as a reality in this world of radical IT transformation. Large corporations like IBM and Accenture have diverted their focus from IT products to Cloud Computing. It has grown into one of the fastest growing sectors in IT. There is a mass exodus to Cloud computing because of its focus on cost savings.

Not only large organizations, but even small and medium size enterprises are readily opening up to Cloud computing to economize their business operations in this environment. Large and expensive computer applications, which were out of the reach of small organizations earlier, are now available on a per-usage basis because of Cloud computing. This helps these organizations to increase the scope of their businesses within a specific budget, by radically expanding because of the availability of complex and often hard to get resources.

One of the most important advantages of Cloud Computing is that it provides efficient computing by centralizing storage, memory processing and bandwidth.

Secondly, it provides an advantage of Almost Unlimited Storage in the age of exhaustible resources. Also the data is centralized due to which data integrity issues are solved as well as data leakages are reduced.

Thirdly, through Cloud computing, the entire system can be deployed very fast in comparison to other methods where the time taken is much more. Also, server downtime is eliminated and transfer time is low. Finally, backing and recovery data become easy as compared to a physical device.

Cloud computing improves organization’s performance by utilizing minimum resources and management support, with a shared network, valuable resource bandwidth, software’s and hardware’s in a cost effective manner and limited service provider dealings. It also helps in performing operations efficiently with minimal cost, least amount of time and the maximum amount of flexibility.

Besides the benefits associated with the Cloud computing, there are different security issues organization has to deal with to separate one Cloud user’s data from the other to maintain confidentiality/privacy, reliability and integrity. As there is a rapid migration to Cloud computing, and limited regulation, there is a massive risk of network security and data safety.

Some of the disadvantages associated with cloud computing are:

Firstly, there is a possible downtime; this means that when your internet connection is down, your business also down. And even the most reliable Cloud computing service providers suffers server outages very often.

Secondly, there is always a concern regarding security issues. Cloud computing refers to Internet computing. So you should not be using Cloud computing applications that involve using or storing data that you feel are so confident that you should not have on Cloud.

Third is the cost of using software as a service, one should be sure of cost that would incur for actual cost of Cloud hosting. When looking forward at implementing Cloud computing option in your business, make sure of cautiously assessing all the various features.

Next is the inflexibility. Since, the Cloud is a new technology, Cloud applications are not as flexible as of now as they will be in future. For example, upgrading environment can result in a loss of data or other malfunction of application.

Another disadvantage is the lack of support; this is a big challenge with Cloud computing implementation. Many SaaS companies have a slow turnaround time to solve client’s problems or queries. However, premium support gives easier access to a customer support team – if a vendor provides you an option for such support, it can certainly be a sensible investment.

As individualized resources are expendable and scarce, there is a growing need for the secure storage, management and the analysis of large amounts of information. This will help in determining patterns and trends which will further assist in gaining knowledge about various things that are used to improve the general well-being of the economy and the country. Because of the significance of applications, it is important that Clouds are secure.
