The document discusses the benefits of moving infrastructure to Amazon ECS. It highlights both obvious benefits like cost savings and faster scaling, as well as less obvious benefits like having open source and private infrastructure, consistency across the organization through standardized tools and templates, increased cost clarity through custom monitoring, and empowering teams with better development tools and cost ownership. The presentation provides examples from Mapbox's experience migrating to ECS and emphasizes how the platform has allowed them to separate infrastructure from applications, standardize practices, run more workloads on spot instances to reduce costs, and give teams more autonomy.
