24/7 State Replication

Systems that operate non-stop, 24/7 are standard in many consumer-facing industries. Often, but definitely not always, these systems do not have aggressive SLAs nor high availability needs to the degree that some financial systems demand. But that is changing. In this session, we will discuss lessons learned in designing systems, especially those based on replicated state machines, that need to continue operating. At the same time, things go wrong, components are upgraded piecemeal, and SLAs must still be met.

Backends in Dart

Monday Oct 24 / 10:35AM PDT

Dart's popularity has surged in the past few years, as it's the language behind Flutter - Google's cross platform front end framework. That's now driving a notion of 'Full Stack Dart', where if you've spent time learning Dart for the front end, why not also use it for the back end.

Leveraging Determinism

Monday Oct 24 / 05:25PM PDT

Determinism is a very powerful concept when paired with fast business logic. We discuss both intuitive and not-so-obvious architecture choices that can be made to dramatically scale and simplify systems with these properties.
