Platform as a Service allows developers to develop their projects by providing layers of hardware and software.
This service includes system management, operating system, programming language environment, database etc. Like platforms. Since system administration is performed by the service provider, you only manage your applications and data. For example with PHP you code a software. You do not have to deal with the SQL and web server infrastructure of the software you code. PaaS only provides the platforms your software needs to work with.
PaaS gives you the platform you need for application design, application development, hosting, testing. Of course, this platform can be configured quickly with the cloud process and you can instantly process it according to your own needs.
In the old model, the developer had to configure, update and keep the platform available. How long will it take to develop in this case, of course? Little or maybe not at all. With PaaS, you are not related to any of the backplane jobs and you can concentrate entirely on your own business.
