Cloud Computing service models

Infrastructure as a Service (IaaS):

This particular service is comprised of a technique for conveying the whole thing from OS to servers.

As they instead get these resources in an outsourced, on-demand service.

Platform as a Service (PaaS):

According to Forrester, it is expected that PaaS can generate about $44 billion in revenues by the year 2020. Among the three Cloud Computing service, PaaS is the most complicated one. Although, it shares some of the common features as that of SaaS. But the main difference between them is that PaaS don’t deliver software online rather it deliver the platform for creating software through Internet.

Software as a Service (SaaS):

In terms of Goldman Sachs report, it has been projected that by 2018 total cloud works of about 59% will be handling by SaaS. Having the authority to provide license of software apps to clientele. SaaS is growing rapidly and providing outstanding opportunity of investment through pay-as-you-go model.

Advantages of Cloud Computing:

Reliability:

Presenting organized and manageable service podium. It is trustworthy development to facilitate client with Service Level Agreement which guarantees 24/7/365 and 99.99% availability. The benefit is that if a server fails, host can quickly and conveniently transited to available server.
