PaaS
Platform as a Service provides a platform for custom applications. The team deploys its code; the provider operates the underlying environment.
What does PaaS mean?
Platform as a Service (PaaS) is a cloud service model in which a provider offers a platform for deploying and running applications. The company uses supported languages, libraries and tools to deploy its own or acquired software. It does not manage the underlying infrastructure and its operating systems itself; it retains control over the deployed application.
A fictional development team releases its project portal on a PaaS. It deploys application code in a runtime supported by the platform. The team designs the portal's sign-in, project permissions and database connection. A managed runtime does not automatically make these application decisions correct. The team checks which additional services, updates or backups are included in the chosen offering.
With IaaS, the team also manages its own operating system. With SaaS, it uses a supplied application. PaaS sits between those levels: the platform is supplied while the team designs its application.
