A scalable runtime environment, Google App Engine is mostly used to run Web applications. These dynamic scales as demand change over time because of Google’s vast computing infrastructure. Because it offers a secure execution environment in addition to a number of services, App Engine makes it easier to develop scalable and high-performance Web apps.

The App Engine SDK facilitates the testing and professionalization of applications by emulating the production runtime environment and allowing developers to design and test applications on their own PCs.

Google App Engine (GAE) is a service for developing and hosting Web applications in Google’s data centers, belonging to the platform as a service (PaaS) category of cloud computing. Web applications hosted on GAE are sandboxed and run across multiple servers for redundancy and allow for scaling of resources according to the traffic requirements of the moment. App Engine automatically allocates additional resources to the servers to accommodate the increased load.

Google App Engine is Google’s platform as a service offering that allows developers and businesses to build and run applications using Google’s advanced infrastructure. These applications are required to be written in one of a few supported languages, namely: Java, Python, PHP, and Go. It also requires the use of Google query language and the database used is Google Big Table. Applications must abide by these standards, so applications either must be developed with GAE in mind or else modified to meet the requirements.

GAE is a platform, so it provides all of the required elements to run and host Web applications, be it on mobile or the Web. Without this all-in feature, developers would have to source their own servers, database software, and the APIs that would make all of them work properly together, not to mention the entire configuration that must be done. GAE takes this burden off the developers so they can concentrate on the app front end and functionality, driving better user experience.
