What is PaaS (Platform as a Service)?

A cloud service model that provides a platform for developers to build, deploy, and manage applications without managing infrastructure.

PaaS provides a complete development and deployment environment in the cloud. The provider manages infrastructure, operating systems, middleware, and runtime — developers focus only on application code and data. Examples include Heroku, Google App Engine, Azure App Service, and AWS Elastic Beanstalk. PaaS accelerates development by providing built-in tools for database management, scaling, monitoring, and CI/CD. It sits between IaaS (more control) and SaaS (less control) in the cloud service spectrum.
