IaaS is the primary foundation of cloud computing. Execution of the other two elements’ depends on this foundation. Virtualization is the keyword that governs this. The service allows an application to be operated and monitored on a virtual computer selected by the users i.e. users can fix up a CPU configuration and the memory storage that is required for a particular application. Eminent cloud computing providers these days offer the entire cloud infrastructure, that include routers, servers, hardware based load balancing, storage, firewalls, and many other network necessities that the user requires. These services can be purchased by the users as and when required. Why Organizations should opt for IaaS? The most important reason for organizations opting for IaaS is the cost. Pay as you Use. The billing is done on a monthly or an hourly basis. Payment is only done for the resources that have been used by the customer. Hence, it is very much opposite to the traditional services, where you had to pay for the total package even if you did not consume the whole.
