Platform as a Service (PaaS) is a cloud computing model that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. In PaaS, cloud service providers offer a platform that includes hardware, software, and tools needed for application development and deployment.
Examples of PaaS providers include Microsoft Azure App Service, Google App Engine, Amazon Web Services (AWS) Elastic Beanstalk, and Heroku. These platforms offer a wide range of services, development frameworks, and tools tailored for different application requirements, making it easier for developers to build and deploy applications without managing the underlying infrastructure complexities.
