As customers build and run production microservices architectures based on containers, having powerful tools to manage the placement and scheduling of these workloads is critical. Amazon ECS allows customers to focus on building their application and removes the need for managing the cluster management software entirely. This session will focus on the capabilities of the new ECS task placement engine, the built-in ECS schedulers, and explore how customers can build custom schedulers using the ECS event stream and Blox, a newly announced open source scheduling framework that gives developers additional choice and control in how they manage containers in production.
