PaaS
PaaS (Perth) stands for Platform as a Service, a service that provides a platform for running applications through the Internet. By using PaaS, it is possible to omit greatly the preparation of the necessary development platform environment (server installation / OS installation / network setting etc) before the application development stage, and maintenance of the platform environment after application development It is advantageous that you can reduce the cost associated with the server load (such as increasing resource according to server load / supporting OS update). IaaS, SaaS can be mentioned as similar words. Both are services provided through the Internet, but they are generally used in consideration of purpose, purpose and future extensibility.
