Your business is growing exponentially. Your computing need & usage is getting bigger with every passing day. Would you add servers & other hardware to meet the new demand

Assume, Recession is back & your business is losing customers. The servers & hardware you added during last quarter's peak season is now idle. Will you sale them Demand keeps on changing based on world/regional economy, sometimes seasonal traffic burst as well.

That's where Cloud Computing comes to your rescue! You just need to configure & your provider will take care of fluctuating demand.

Your business should focus on your core competency & should not worry about security, OS, software platform, updates and patches etc. Leave these chores to your provider.

From an end users perspective, you don't need to care for the OS, the plug-ins, web security or the software platform. Everything should be in place without any worry.

Resource Sharing is the beauty of Cloud Computing. This is the concept which helps the cloud providers to attain optimum utilization of resources. Say, a company dealing in gifts may require more server resources during festive season. A company dealing in Payroll management may require more resources during the end or beginning of the month. The cloud architecture is implemented in such a way that it provides you the flexibility to share application as well as other network resources (hardware etc). This will lead to a need based flexible architecture where the resources will expand or contract with little configuration changes.
