Orchestration Service for a Distributed Computing System

An apparatus comprising:

• one or more computer processors;
• and
• a non-transitory computer-readable storage medium comprising instructions, that when executed, control the one or more computer processors to be configured for:
• providing a first orchestration service instance for managing a set of containers operating on a controller node, wherein the controller node controls a set of physical nodes;
• and
• providing a set of second orchestration service instances for managing a set of first services operating in the set of containers, wherein a second orchestration service instance in a container manages a respective first service in the container,
• wherein:
• the set of physical nodes include a set of third orchestration service instances for managing a set of second services operating on the set of physical nodes, and
• the first orchestration instance, the set of second orchestration service instances, and the set of third orchestration service instances communicate through a shared communication service that maintains a global state of the controller node, the set of containers, and the set of physical nodes.
