The second level is called PaaS (platform as a service). Users of complete processing platform and in perfect condition is generated without requiring purchase and support hardware and software. Serve as an example, a web developer needs a web server to serve its pages, a database server and operating system. PaaS is in charge of providing all these services. And finally, software as a service (Software as a Service). It is the lowest level and is in charge of delivering software as a service through Internet.
