Cloud Computing: A paradigm shift

What is Cloud Computing?
Cloud computing is all about taking care of scalability and availability of a software application by providing highest level performance and security from application architecture perspective. There are several cloud providers in the market. The one famous and rapidly growing are Microsoft, Google and IBM.

How cloud is changing the current market and technology development?

From developers’ perspective cloud computing is nothing but coding and deploying an application on a shared location which may be outside of your company. The shared location may be from Google, IBM,  Microsoft, TCS, Infosys or other Cloud providers. This shared location consists of very huge set of hardware, software and system software to dynamically manages these set of h/w and s/w across the multiple client applications based on different set of predefined criteria. The cloud internally is nothing but shared infrastructure of hardware and software.

The cloud providers take care of the application’s ever increasing load and/or space requirement and automatically adjust the RAM, processing power, space required running the application smoothly. It main aim to provides good response time to the end users.

1.      We should understand that what it takes/means/required from an application point of view, so that we will be able to migrated an application from a dedicated hosted environment to a cloud infrastructure. We must consider the benefit and shortfall before choosing the migration from a dedicated (company's internal environment) to a cloud hosting provider.

2.      We should be able to dig dip into application/s  prescribed to a standard set of architecture need of a banking client so that we will be able to size the amount of work that needs before we can deploy the application on the cloud. The amount of work will actually be key point to reach at decision of choose a cloud services or not.

3.      We should understand what it will take to architect applications that can run on the cloud to optimally use the cloud infrastructure.

4.      We should also understand and get the result that what cloud cannot be solving (in its current form). This will make sure that we do not mess up as cloud zealots. It will keep us ready to take right decision when time demands for a cloud change.
