Google App Engine integrates with Google's CDN out of the box and it distributes your application's assets through that, increasing loading speed considerably.

Google App Engine is very easy to use. All you need to do is install the SDK (which in itself is easy as well, and the documentation is very heplful) and run the command needed depending on the type of project to deploy it.

For example, to deploy a golang application, you run golang deploy inside the project folder and it will be automatically deployed.
