Netflix sought to increase availability beyond the capabilities of a single region. How is that possible, you ask? We walk you through the journey that Netflix underwent to redesign and operate our service to achieve this lofty goal. Using the principles of isolation and redundancy, our destination is a fully redundant active-active deployment architecture where end users can be served out of multiple AWS regions. If one region fails, another can quickly take its place. Along the way, we'll explore our Isthmus architecture, a stepping stone toward full active-active deployment where only the edge services are redundantly deployed to multiple regions. We'll cover real-world challenges we had to overcome, like near-real-time data replication, and the operational tools and best-practices we needed to develop to make it a success. Discover a whole new breed of monkeys we created to test multiregional resiliency scenarios.
