Understanding the Different Models for Cloud Computing Services

When you hear the term “cloud computing,” you might think that it is the same thing to everyone. However, like the sky borne object from which it gets its name, cloud computing is something that changes depending on who is viewing it and experiencing it. However, when you get down to it, Companies base their cloud computing services on three basic models: software as a service, platform as a service, and infrastructure as a service. In order to figure out which one is best for you and your company, you need to understand what each one is and the way you can use it.

Here is a description of each of these services and the way they would benefit a company.

1.SaaS or Software as a Service In this cloud computing model, the cloud provides almost everything that a company needs through a thin client or a browser. The client needs to provide a minimal desktop computer for each user. The user then logs into the system through the thin client or browser. They see a list of applications to which they have access. They only have access to what you allow them to see.

2.PaaS or Platform as a Service In this computing model, the client gets a platform on which to load their own applications. This model is perfect for a company that does software development. They can get identical platforms setup for different stages of software development. Some companies also provide the tools necessary for software deployment. This model is ideal for companies that do not have the money to buy their own systems, but want the option to have multiple servers available.

3.IaaS or Infrastructure as a Service With this model, the client gets space on servers, networks, and other pieces of infrastructure from the service provider. The client only pays for the amount used in a given month or other period. This model works much like a utility company. It is a cost effective model for companies that have only a few employees but foresee growth. If there is a brief surge in employees at holiday times, the service scales to cover it. Then when the surge goes down, the amount paid also goes back down. This is a good option for companies that do not have a great deal of data to secure, but still need computing power at their fingertips.
