Google have built an open-source set of client libraries that take care of all the nitty-gritty detail of connecting, and managing Maps API services for both Java and Python.
Alex Danilo introduces these libraries, and what they do - allowing Java and Python server side application developers to save time integrating Maps API services into their applications.
These libraries streamline and simplify the work required to get an application up and running by taking care of things like retry for dropped connections, rate limiting to make sure applications manage their quota, and more.
Documentation for the client libraries is on the Google Developers Site here, and the open source project code is on github here.
If you develop in Java or Python, you should definitely take a look.
