PaaS, or Platform-as-a-Service, is the new wave of computing. It’s computing in the cloud. It’s cheaper per unit, more efficient and more versatile than traditional computing. But how exactly does it work?

With PaaS, instead of comparing applications, buying and configuring them to work on your in-house computer systems, and hiring people to maintain them and service them on a continuous basis, you can just pay for the applications that you need when you need them. Much like a public utility, you pay only for what you use and only for the applications that you are using. Nothing more.

There are, of course, different types of PaaS solutions.

  • Computing platforms can include bandwidth and storage as well as other traditional computing needs on a service-by-service basis;
  • Web applications platforms such as those provided by Google Apps and Google Docs;
  • Social-based apps like Ning and Facebook;
  • And business applications platforms, which are becoming all the more popular as we speak.

These different types of PaaS all serve one purpose: To allow you, the business owner, to maintain your core business unaffected by the technology required to manage it; rather, you can contract to buy and use only those applications that you really need to run your business and buy just the right amount to get done the functions you need done on a daily basis.
