What is PaaS (Platform as a Service)?
Platform as a Service is a cloud computing model that delivers applications over the internet. In a PaaS model, a cloud provider delivers hardware and software tools – usually those needed for application development – to its users as a service. A PaaS provider hosts the hardware and software on its own infrastructure. As a result, PaaS frees users from having to install in-house hardware and software to develop or run a new application.
How is Platform as a Service (PaaS) different from Infrastructure as a Service (IaaS) and Software as a Service (SaaS)?
While all three are cloud computing models that use the internet to deliver some or all of its services, the main difference lies in which services a provider manages and what a company manages. In the case of Platform as a Service (PaaS), a third-party provider manages most of the system’s services, such as servers and storage, while the company running the system manages its own applications and data.
