High availability (HA) isn’t just about keeping the lights on all the time; it’s also about quickly turning them back on when they unexpectedly go out. With software, this means capabilities for fault tolerance as well as backup and recovery. Docker Datacenter (DDC) provides this for both the container-based applications as well as the application infrastructure components (such as cluster management, orchestration, account settings, etc.). In this post we will look at how high availability is achieved in the latest release of Docker Datacenter. As a refresher, Docker Datacenter is comprised of the following software: Universal Control Plane (UCP) with…

Additionally, as these services scale horizontally across the cluster, they should be equally utilized for maximum load distribution.
