Google App Engine Opens to Developers

Google launched App Engine in April 2008 as a platform for building web applications without managing servers directly. The first version focused on Python applications and provided managed services for storage, authentication, caching, and request handling.

Unlike renting a virtual machine, App Engine hid most of the operating system. Applications ran in a restricted sandbox and had to use Google’s APIs for many tasks. That limitation reduced control but allowed Google to scale instances automatically and handle much of the infrastructure work for the developer.

The service became an early example of what would later be called Platform as a Service. It showed a different cloud trade-off from Amazon EC2: instead of giving developers a virtual server, the provider could offer a more constrained application environment in exchange for less operational work.
