The Birth of Google App Engine

Google App Engine, often referred to as GAE, was introduced by Google in 2008 as a fully managed platform-as-a-service (PaaS) for developing and hosting web applications. With GAE, developers could focus on writing code while leaving infrastructure management to Google, streamlining the development process.

How does cloud computing work in the Google app engine?

Google App Engine is a Platform as a Service (PaaS) that provides a fully managed environment for hosting web applications. This means that Google takes care of all the infrastructure requirements, such as provisioning servers, managing operating systems, and deploying applications.

When you develop an application for Google App Engine, you simply write your code and deploy it to App Engine. App Engine will then take care of running your application and scaling it up or down as needed. This frees you up to focus on developing your application without having to worry about the underlying infrastructure.

The architecture of Google App Engine

Google App Engine’s architecture can be understood at three main levels:

1. High-Level View:
