Andrew is a Linux generalist that loves to work on large scale distributed systems. He works on Facebook's MySQL Infrastructure team and is focused on operational efficiency of both humans and servers. This is done by building new software robots that take over more and more of his co-worker's jobs from them, and mediating the arguments that these young and sometimes overly opinionated robots get into.
Since the beginning, Facebook has used a conventional username/password to secure access to production MySQL instances. Over the last few years we've been working on moving to x509 TLS client certificate authenticated connections. Given the many types of languages and systems at Facebook that use MySQL in some way - this required a massive amount of changes for a lot of teams.
This talk is part technical overview of how our new solution works and part hard-learned tricks for getting an entire company to change their underlying mysql client libraries.
