Orchestration platforms let us work with higher level ideas like services and jobs; but there is more to a platform than scheduling and service discovery. A platform is a collection of actors and APIs that work together and provide those higher level abstractions on a distributed system. In this session we'll go deep on the architecture of open source orchestration platforms, consider scaling pains, reveal extension points, and reflect on an orchestration platform at Amazon. We'll finish with a demo of a homemade abstraction deployed on a live, multi-cloud Swarm cluster. -- Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.
