Applications that exist in a Docker container are
- Complete in configuration and setup
- Docker swarms are
- Load balanced
- Fault tolerant
All of the tasks, work, and architecture that previously was manually managed by disparate groups and individuals is automated in a reliable and feature complete system automatically by using docker in swarm mode.
An application developer can deploy a docker image that is then run in swarm mode and it will be as if an entire team of individuals monitor and maintain the application automatically by the docker swarm infrastructure.
