Cloud computing refers to a paradigm shift to overall IT solutions while raising the accessibility, scalability and effectiveness through its enabling technologies. However, migrated cloud platforms and services cost benefits as well as performances are neither clear nor summarized. Globalization and the recessionary economic times have not only raised the bar of a better IT delivery models but also have given access to technology enabled services via internet. Cloud computing has vast potential in terms of lean Retail methodologies that can minimize the operational cost by using the third party based IT capabilities, as a service. It will not only increase the ROI but will also help in lowering the total cost of ownership. In this paper we have tried to compare the cloud computing cost benefits with the actual premise cost which an organization incurs normally. However, in spite of the cost benefits, many IT professional believe that the latest model i.e. “cloud computing” has risks and security concerns. This report demonstrates how to answer the following questions: (1) Idea behind cloud computing. (2) Monetary cost benefits of using cloud with respect to traditional premise computing. (3) What are the various security issues and how these threats can be mitigated? We have tried to find out the cost benefit by comparing the Microsoft Azure cloud cost with the prevalent premise cost.

We all have probably heard of cloud computing. New technologies are bound to pave its way into our lives faster than the Formula Rossa rollercoaster in Abu Dhabi. We may not be aware of it, but we all have been exposed to the cloud computing technology.


This article made me aware that cloud computing is about two things: (1) that it can provide moving services and (2) it has transformed IT hardware requirements into a simple cost-effective scheme. This simply means that for developers, they can now create/ provide applications without worrying about hardware purchases. For companies, this means saving up on capital and operational expenditures thus, avoiding unnecessary expenses. One example would be purchasing of servers. We all know that servers are not just expensive, they also wear out in time. Unless we are able to maximize its use, it is just money thrown down the drain. 


I also learned that there are 3 major categories of services provided by cloud computing services. They are: (1) Infrastructure as a Service (IaaS), (2) Platform as a Service (PaaS) and (3) Software as a Service (Saas). 


IaaS is about building Application Program Interface (APIs) and make it available to costumers through a pay-as-you-go service wherein they can only pay for the amount of service they are able to get. (Example: Amazon) SaaS on the otherhand uses these APIs to create their own applications. (Example: Salesforce). Lastly, SaaS allows users to use their applications and that alone. (Good example: Facebook, Twitter)


From an information specialist point of view, cloud computing services could mean a better understanding of information management through the web. It could give us a more graphical presentation of where our information goes, what it does once it is in the cloud and how to be able to present information to those who need it.
