This video explores DoorDash's journey from a monolithic architecture to a cell-based microservices architecture on AWS to support hyperscale growth. Anand, a Senior Solutions Architect at AWS, and Jay Wallace, an Engineering Manager at DoorDash, discuss the evolution of DoorDash's technology stack and the implementation of their 'Supercell' project. They delve into the challenges of running microservices at hyperscale and how cell-based architecture addresses these issues. The presentation covers key concepts such as failure isolation, deployment strategies, and the benefits of using AWS services in designing and implementing this architecture. DoorDash's experience provides valuable insights for companies facing similar scalability challenges in their digital transformation journey.
