Public PIRs make us more transparent and accountable to our customers. Most customers understand that incidents can occur. Our timely communications and commitments to preventing similar incidents in the future help restore trust. How it's intended to be used Fast five" is a process for safely making data schema changes and updating the associated code (or configuration) that depends on those changes. Our goal is to prevent situations where we have tight coupling between code and schema changes that prevent us from being able to recover to a healthy state if something goes wrong. Fast five can be summarized as: Elliot Scheiner: Yeah, well a lot of time you just get a vibe and a feel for something and it just comes together. Then you look at it and say “How much am I actually going to improve this mix.” I mean if it feels great and sounds great I’m a little reluctant to beat it into the ground. These are techniques where code and configuration changes are released to a subset of users or a subset of the production cluster and monitored for anomalies. The changes only continue to roll out to the wider population if they behave as expected. Preproduction deployments We would rather take a reasonable delay in releasing a new product to build it on our platform rather than building custom functionality that duplicates existing platform capabilities.

These documents must be written as if they can easily be understood by an outside developer. We refer to this mindset as "third-party first" thinking. Whereby we build our internal components and documentation to the same level of quality we would use for external (or third-party) developers. Developing accessible software What it isObjectives and Key Results are a goal-setting method we use across the company. OKRs can be set at different levels such as company, department, or team. OKRs represent goals for achieving something new, like increased customer engagement, or new levels in performance or reliability.

Our mission is to help unleash the potential of every team. We simply cannot achieve this mission unless our products are accessible to everyone. Our products need to usable by people who have permanent or temporary disabilities so they can do the best work of their lives when they use our products. Anyone can contribute to the body of knowledge in a structured manner using an RFC or a pull request. Elliot Scheiner: Not necessarily. In the days when I was working at A&R, we had no remotes on any of our plates there. Phil wanted to make changing them difficult because he tuned them himself and he really didn’t want anybody to screw with them. There would be at least 4 plates in every room. Some of them might be a little shorter than another but generally they were in the 2 to 2 1/2 second area. There was always an analog tape pre-delay, usually at 15 ips, going into the plates. The plates were tuned so brilliantly that it didn’t become a noticeable effect. It was just a part of the instrument or part of the music. You could actually have a fair amount on an instrument and you just wouldn’t notice it. This was the solo that goes in “Heartbreaker”. It was the era when a record could come out within a week or two of completion, so the next week that record came out. It enables a workflow to prevent steps from being missed during the release of any change. The workflow also ensures collaboration between all of the participants in the process, including:

How often the team deploys new code to a production environment. For pipelines that don't deploy directly to a prod environment, we look at successful builds on the main branch. We expect our teams to use, contribute, and enhance our common services, libraries, patterns, and guidelines. Guidelines for prioritization

Use existing patterns: We leverage existing patterns where possible to stand on the shoulders of the work that’s come before. By leveraging the mistakes of the past, we are able to build more secure, reliable, performant, and efficient components. When teams improve existing patterns or establish new ones, those improvements are shared with our entire organization. Our public engineering blog—This is our engineering blog where we publish content to inspire our community. Learn how to be a great maintainer of an open-source project, particularly one that accepts external contributions Design for failure: Failures are inevitable. The best designs are resilient, degrade gracefully, and protect the other components they interact with. Testing for failure scenarios is often more important than testing for normal operations.We want to share the way we work with everyone, to help improve teams across industries. Hopefully, our learnings will help you build autonomous teams and ingrain ownership in your own organization. Similar to a pull request, a few relevant peers and, in most cases the team architect, should review the document to validate the approach. The document should be open to anyone in the company to view or comment on. All engineers are required to read and follow our policy for disaster recovery. Maintaining existing certifications and assisting an audit The meeting brings together senior staff (managers and engineers) from all cloud teams and includes a cross-company operational review of incidents and dashboards. It also includes a rotating deep dive into one of the teams’ scorecards and practices, with the intent of creating mindshare around operational health that cuts across all cloud teams.
