Quick Scoop

Platform as a Service, or PaaS, is a cloud computing model that gives developers a ready-made environment to build, test, deploy, and manage applications without handling the underlying servers, storage, or operating systems.

How it works

In PaaS, the cloud provider runs and maintains the platform, including infrastructure and core software components, while you focus on your application code. That usually means the provider handles scaling, patching, runtime management, and much of the middleware setup.

Why people use it

  • Faster development, because teams do not need to build the full environment themselves.
  • Less maintenance, since the provider manages most of the backend stack.
  • Easier deployment and scaling for web apps and APIs.

Simple example

A team building a web app might use PaaS to deploy code directly from their laptop or CI pipeline, while the platform automatically handles runtime setup and traffic growth. This is useful when the goal is to ship features quickly instead of managing servers.

How it differs

PaaS sits between Infrastructure as a Service and Software as a Service. With IaaS, you manage more of the stack yourself, and with SaaS, you mainly just use the finished software.

TL;DR: PaaS is a cloud platform that lets you focus on building apps while the provider takes care of the infrastructure and most platform management.
