Advancing Our Chef Infrastructure

Advancing Our Chef Infrastructure

摘要

At Slack, we manage tens of thousands of EC2 instances that host a variety of services, including our Vitess databases, Kubernetes workers, and various components of the Slack application. The majority of these instances run on some version of Ubuntu, while a portion operates on Amazon Linux. With such a vast infrastructure, the critical question arises: how do we efficiently provision these instances and deploy changes across them? The solution lies in a combination of internally-developed services, with Chef playing a central role. In this blog post, I’ll discuss the evolution of our Chef infrastructure over the years and the challenges we encountered along the way.
