Docker Swarm is a lightweight, easy-to-set-up tool for quick deployments and smaller projects.
Key differences: Kubernetes requires more setup time, designed for massive workloads, offers self-healing and advanced networking. Docker Swarm is quicker to set up, works well for small to medium-sized applications, provides basic failover, and simpler networking.
Choose Kubernetes for high availability, auto-scaling, microservices at scale, multi-cloud deployments, advanced networking, security policies, and granular control. Choose Docker Swarm for quick deployments, small to medium-sized applications, familiarity with Docker, and when simplicity is preferred.
