Final Thoughts
The containerization landscape offers a range of tools from foundational engines like Docker and Podman to powerful orchestrators like Kubernetes, and comprehensive managed platforms from cloud providers (EKS, GKE, AKS) and vendors like Red Hat (OpenShift) and SUSE (Rancher). Kubernetes remains the de facto standard for orchestration at scale, but its complexity drives adoption of managed services and simpler alternatives like Nomad. Security, ease of use, ecosystem integration, and cost remain key differentiators.
