Platform as a Service (PaaS)

PaaS solutions are development platforms for which the development tool itself is hosted in the cloud and accessed through a browser. With PaaS, developers can build web applications without installing any tools on their computer and then deploy those applications without any specialized systems administration skills.

What Makes PaaS Different?

The alternative to PaaS is to develop web applications using desktop development tools like Eclipse or Microsoft Access, then manually deploy those applications to a cloud hosting provider such as Amazon EC2.

PaaS platforms also have functional differences from traditional development platforms. These include:

  • Multi-tenant development tool: traditional development tools are single user - a cloud-based studio must support multiple users, each with multiple active projects.
  • Multi-tenant deployment architecture: scalability is often not a concern of the initial development effort and is left instead for the system administrators to deal with when the project deploys. In PaaS, scalability of the application and data tiers must be built-in (e.g., load balancing, failover need to be basic elements of the dev platform itself).
  • Integrated management: traditional development solution usually do not concern themselves with runtime monitoring , but in PaaS, the monitoring ability needs to be baked into the development platform.
  • Integrated billing: PaaS offerings require mechanisms for billing based on usage that are unique to the SaaS world.
