What is Platform as a Service – PaaS?

PaaS (Platform as a service) is a Cloud computing service that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining an infrastructure typically associated with it. This solution is designed and thought for developers to help them develop and test apps without having to worry about the underlying levels (meaning provisioning of servers, storage and backup and all the infrastructural aspects). PaaS performs all the back-end work about setting up servers automatically and transparently in the background, so that developers can totally focus on writing code. In a PaaS environment, the service provider not only is responsible for provisioning and managing the lower level infrastructure resources, but also for providing a fully managed application development and deployment platform. The biggest added value of PaaS is that developers are completely abstracted from the lower-level details of the environment, so they can fully focus on writing code without having to worry about scalability, security and availability. In addition, PaaS helps businesses to minimise operational costs and increase productivity through a quicker time to market.
