What is Platform as a Service?
Platform as a Service(PaaS) provides the developers an environment to develop an application or software with ease. The developers just need to develop the product, without the worry of building and maintaining the infrastructure. The major advantage of PaaS is that it allows the app development to be much more effective, by reducing the complexity that is associated with high level programming as it also provides the environment itself. The disadvantage of PaaS is that sometimes it can be locked onto a specific version which cannot be changed later.
