# Kinto Example
2+
3+
This is a basic example of running Mozillas [Kinto](https://github.com/Kinto/kinto/blob/master/docs/index.rst)
4+
on Managed VMs. Kinto provides a framework to sync JSON data across many devices and provide push notifications.
5+
Thius example uses a custom runtime to install Kinto and edit the config to run it on port 8080, which is the port that
6+
the base Docker image is expecting.
7+
8+
Since Kinto is being imported as a Python library and run as-is, no additional code is necessary.
9+
10+
Note that this is using Kinto's basic in-memory backend. As such, the instances are tied to 1. A production
11+
version of Kinto would use a PostgreSQL database and Redis cluster, which would allow scaling to many instances.
12+
13+
If you are interested in seeing this example expanded to use PostgreSQL, you can file an Issue on the Issue
14+
Tracker, or submit a Pull Request if you've accomplished it yourself.
