Backend as a Service, or BaaS (sometimes referred to as mBaaS) is a cloud computing category that consists of companies that make it easier for developers to setup, use and operate a cloud backend for their mobile, tablet and web apps. It provides web and mobile app developers with a way to link their applications to backend cloud storage while also providing features such as user management, push notifications, and integration with social networking services. These services are provided through customized Software Development Kits (SDKs) and Application Programming Interfaces (APIs). Cloud backend as a service platforms enable app developers to store, manage and access their data through such cloud. Moreover, they are able to develop backend features for their apps in minutes, rather than weeks.
