Cloudflare: Performance isolation in multi-tenant DB

Cloudflare is no longer "just" a CDN serving 55M HTTP requests/sec; they now offer a wide range of cloud services on the edge. These services run on a data layer with 15 Postgres clusters running hundreds of databases. Vignesh Ravichandran, engineering manager of Cloudflare's database team, joined us to discuss the challenges of running this large-scale multi-tenant environment - dealing with network partitions, noisy neighbors, floods of connections, and even global warming. We talk about the importance of having a good toolset, of practicing incidents, and of internally advocating database best practices to a large engineering organization.
