Put a Button on it: Removing Barriers to Going Fast.

For most companies, pushing code to production is a slow and painful process that can span hours or days, and is done very infrequently because of this and other general anxieties behind public facing launches. At Etsy, we built a tool called Deployinator to make it a painless process for everyone to push code at will. We pair this with a suite of tests, graphs, and metrics to make high velocity change safe and transparent.
