Platform as a Service (PaaS)

Definition

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. This model simplifies the development process by offering pre-configured software and services, making it easier for developers to focus on writing code and deploying applications. PaaS fits into various IT business models by enhancing collaboration, reducing time-to-market for new applications, and supporting innovation in the tech industry.
