Episode notes

Instagram is a team that is production engineering slash SRE, slash platform engineering. The pressure engineers at Instagram meta have a deeper focus in the areas that they're responsible for. They are not really working on like an infrastructure component. Instead, we're sort of taking the mindset that it takes to build,. you know, a database, or a queuing system, and we're trying to apply that to a product.

Jack Li explains how his production engineering team rolled out a new incident review process, how they’ve made the case for investing in reliability, and specific tools his team has built to improve reliability.
