Decision at Uber Technologies about Puppet Labs, Mattermost

Why we piggybacked on the open source Mattermost for Uber's chat needs, which we open sourced as uChat ( GitHub : https://github.com/uber-uchat/ -- contributing some of our changes back to Mattermost as well in the process.)

With operations in over 620 cities, it was paramount for us to identify a chat solution that would enable Uber employees to reliably communicate on desktop and mobile regardless of where they were in the world. To accomplish this, we established a few core requirements. To start, we needed something that could scale to support our growing employee population and, as a byproduct, control costs. We also needed a platform that could easily integrate with a variety of internal engineering, business, and operational tools.

While we evaluated Internet Relay Chat (IRC) and many other popular chat clients, it became clear that there was no turnkey third-party solution able to meet Uber’s core requirements.

So after testing multiple off-the-shelf alternatives, we built uChat, our custom in-house messaging platform, by leveraging open source platform Mattermost and Puppet Labs , the Uber standard for deployment configuration management. In this article, we discuss how in just three months our team transitioned the company to a new solution capable of reliably delivering over one million messages per day to tens of thousands of users, all in one unified chat environment:
