The type of cloud computing service that allows users to run applications over the internet without managing the infrastructure is known as Platform as a Service (PaaS). PaaS provides a complete development and deployment environment in the cloud, including hardware, software, and services needed for application development and maintenance. Users can focus on writing code and deploying applications while the cloud provider handles all underlying infrastructure aspects, such as servers, storage, and networking. This approach accelerates the development process and reduces operational overhead for organizations.
