Abstract On a high level, the talk addressed following questions: What is Edge and why are the benefits of edge? What are the challenges of implementing Postgres at the edge? How we implemented it at Cloudflare? Where Postgres at the edge is heading? Slides from the presentation Link from Developerweek Cloudx Link from Developerweek Cloudx virtual

Abstract We talked about the importance of having a good toolset, of practicing incidents and of internally advocating database best practices to a large engineering organization. Recordings of the presentation

Abstract With the advent of cloud/managed offerings, running Postgres on their own hardware is becoming rare. It’s great that a lot of the Ops work is taken care of by the provider, however, understanding a layer or two beneath these abstractions will be useful for anyone in strengthening their knowledge. For eg. When you can’t connect to an instance how do you find where the problem is? a. Are you able to reach the server i.

Abstract This talk explores how Cloudflare uses HAProxy for health checks, load balancing and reading traffic among nodes set up with Postgres streaming replication in hot standby mode. Cloudflare operates multiple Postgres Clusters across four data centers, and all of these clusters are made up of six nodes. During a primary failure, Cloudflare’s high availability system promotes a replica to become a primary, and HAProxy makes sure there is no write traffic between two primaries to avoid a split-brain scenario.
