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.
