Infrastructure as a service - The Base for Cloud Computing

Infrastructure as a Service is described as a model, where an enterprise outsources the devices required to assist
operations, which comprise of various networking, storage, servers and other hardware components. The
managed service provider is in charge of the equipment and is accountable for operating, maintaining and
housing it. The client or the end user simply reimburses on a per-use mode.

The basic features of Infrastructure as a service would include the following:-
Desktop virtualization
Dynamic scaling
Internet connectivity
Services based on a policy.
Administrative agendas and tasks are automated
Along with being a billing model, it is also a utility computing service

IaaS forms one of the three major components of cloud computing. The remaining two are namely Platform as a
Service (Paas) and Software as a Service (Saas). There are times when IaaS is referred as Haas, which means
Hardware as a Service.

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.

Today more and more companies are opting for Infrastructure as a service (IaaS). This is because Cloud by nature
is elastic and one can organize the amount of resources utilized at operation at a given time. In addition to that,
owing to an individual users computing configuration and needs, the IaaS provider is able to respond faster
whether to scale down or up the present system.
