Architecting for Confidence: Building Resilient Systems

For any complex system, there is a wide array of activities that can increase system reliability and operator confidence. Each activity contributes in a different way.

If your system is safety-sensitive, you may invest heavily in pre-production testing strategies. If you want to holistically understand the effect of a change on individual users, you may use a sticky canary. If you don’t know your resource limits or bottlenecks, a load test could be useful. To validate design decisions around reliability mechanisms that don’t get exercised regularly, you may run chaos experiments. All these activities converge to build a stronger system that holds up to the pressures of production, but eventually your operators will have to engage to triage outages. When they do, it’s important they are comfortable doing so.

In this track, we will delve into each of these areas to provide attendees with the tools they need to build resilient systems and empower operators.
