"Container orchestration" in cloud computing refers to the management and automation of software containers, which package applications and their dependencies. Orchestration tools help deploy, scale, and manage containerized applications across various environments efficiently. They ensure that containers are operating as expected, handle load balancing, and facilitate self-healing processes in case of failures. Key technologies for container orchestration include Kubernetes and Docker Swarm. This orchestration enables flexibility, portability, and improved resource utilization in cloud-native applications.
