PaaS stands for Platform as a Service. It is a cloud service model that allows developers to build, test, and deploy applications without managing the underlying infrastructure. With PaaS, users can focus on programming and development rather than dealing with hardware, operating systems, or storage. This service typically includes resources such as an application framework, database management systems, and developed tools for collaboration. By providing these capabilities, PaaS enhances efficiency and accelerates the development cycle, making it particularly valuable for businesses seeking to innovate rapidly.
