	Platform as a service is defined as as a service ~~which allowes~~ developers to host Web Applications without the ~~hassele~~ of ~~seeting~~ up the entire ~~infracstructure like Servers~~, load balancers, cache, ~~database server~~. ~~The~~ developer can focus on building the application ~~and the~~ infrastructure management is taken care by the PASS providers.		Platform as a service is defined as as a service that allows developers to host Web Applications without the hassle of setting up the entire infrastructure. Usually this infrastructure includes a server, or multiple ( for hosting ), load balancers to manage client requests and traffic, a cache and a database. All of these layers require know-how and time both for setup and installation, as well as for maintenance. With Platform as a service, the developer doesn't have to worry about any of the setup or maintenance required to run a successful web service, and instead can focus on building the application. The infrastructure management is taken care by the PASS providers.

	Cloud Hosting is defined as as provision of virtual servers on the cloud. It is also ~~called~~ as ~~Infrasturucture~~ as a Service. The service provides you Vanilla Virtual Servers. You are provided with root access to the server. You can install any packages to this server. It can be used as load balancer, database server, cache server.		Cloud Hosting is defined as a provision of virtual servers on the cloud. It is also referred to as Infrastructure as a Service. The service provides you Vanilla Virtual Servers. You are provided with root access to the server. You can install any packages to this server. It can be used as a load balancer, database server, cache server or whatever may be required for the application.

	The dynos have an ephemeral file system. This means that as a developer, you never know when files written to disk will disappear. If a dyno stops or is restarted, the files are gone. This means that any applications hosted in heroku ~~shouldn’t~~ rely on any sort of local storage in order to work, since at the drop of a hat, that storage might be gone, and there’s nothing that you can do about it.

	OpenShift provides similar features as compared to Heroku. Unlike working on a dedicated box, you don’t have to setup the server , the packages, dependencies, DNS, Web server. OpenShift provides allied services like backup, security, logging, monitoring. It also has a marketplace of apps which can be integrated with your application. This removes the tasks of working on the setup and helps you focus on you main idea. There is no need for a database administrator or DevOps.
