When architecting a critical system the Availability of CAP theorem becomes the most important element. Architecture measures availability in 9s with 99.99% equating less than 1 hour of unplanned downtime. This session will focus on what it takes to get there.
After establishing high availability expectations and measurements, this session will dive into what it takes to establish the highest scale possible. It includes a look at infrastructure needs with a separation between capacity and scale. A look a service discovery with pro and cons of service to service dependencies. We look at infrastructure necessary such as health checks and monitoring. The session will include a look at different layers of fault domains including cross region.
