Cloud computing has become diverse enough now to warrant consulting. Any enterprise that wishes to make the transition to the cloud or benefit by moving a specialized part of its business, needs to understand the various cloud computing models available.
Let’s look at the popular delivery models and what they mean for businesses:
- Software-as-a-Service: Better known as SaaS, this is where cloud computing initially began. The idea behind was to do away with having to install software on a local machine, and instead provide Web-based applications that are easy to use and customize. An example can be accounting software or CRM software accessed remotely.
- Platform-as-a-Service: For some businesses the existing SaaS solution may not be enough. For them cloud computing provides PaaS, offering virtual platforms that they can extend. This has a great plus for small businesses who now don’t need to spend a lot on expensive software. PaaS has led to increased competition and improvement in software quality.
- Infrastructure-as-a-Service: IaaS is truly the culmination of cloud computing, as it offers the ability to scale your infrastructure virtually. Thus, a business can increase capability by scaling up their hardware resources—storage, processing, servers, etc.—without having to create additional physical space, and only at a very small cost.
Cloud computing is indeed reshaping the existing conception of enterprise computing. Having a clear idea of these fundamental models helps in picking up the right vendor and pricing plan, in addition to improving efficiency.
