In Docker, orchestration specifically refers to the management and coordination of multiple containers. As applications become more complex and are composed of numerous containers, orchestration becomes essential for automating the deployment, scaling, and operation of containerized applications.

Orchestration tools, such as Kubernetes, Docker Swarm, and Apache Mesos, facilitate tasks such as service discovery, load balancing, scaling up and down based on demand, rolling updates, and health monitoring of containers. This coordination enables seamless communication between containers and ensures that they work together effectively as a unified application.

While running containers independently, enforcing security policies, and creating backup images are important aspects of working with Docker, they do not encompass the broader organizational needs addressed by orchestration. Orchestration is focused on the collective management of these containers, ensuring they operate harmoniously within a larger application framework.
