Google App Engine is a PaaS that allows developers to build and deploy web applications in the cloud without having to manage servers or databases. It provides automatic scaling, high availability, and free usage up to certain quotas. Developers use the App Engine SDK to build and test applications locally before deploying them to Google's infrastructure where App Engine services like Datastore, Memcache, and Google Accounts handle scaling and management.
