In this 'Back to Basics' video, Franklin explores how to enhance application scaling and resiliency using cell-based architecture. He discusses the challenges of managing large-scale systems and introduces cell-based architecture as a solution. This approach involves deploying multiple independent replicas of an application over a gateway router, providing fault isolation, easier testing, safer deployments, and improved scalability. Franklin explains the benefits of cell-based architectures, including better fault containment, higher mean time between failures, and lower mean time to recover. He also touches on implementation considerations and how this architecture can evolve with changing business needs.
