Platform as a Service (PaaS)
(PaaS) is a cloud computing model in which a third-party provider delivers hardware and software tools, usually those needed for application development to users over the internet. A PaaS provider hosts the hardware and software on its own structure. As a result, PaaS frees users from having to install in-house hardware and software to develop or run a new application. PaaS does not typically replace a business’s entire IT infrastructure. Instead, a business relies on PaaS providers for key services, such as application hosting or Java development.
