Docker Swarm
Docker Swarm is a native clustering and orchestration tool for Docker containers, enabling the management of a cluster of Docker nodes as a single virtual system. It provides features like service deployment, scaling, load balancing, and rolling updates for containerized applications. While not specifically a GPU-focused tool, it can be integrated with GPU resources through Docker's GPU support and third-party extensions.
Developers should use Docker Swarm when they need a simple, built-in orchestration solution for Docker environments, especially for small to medium-scale deployments where Kubernetes might be overkill. It's ideal for scenarios requiring high availability, load balancing, and service discovery across multiple Docker hosts, such as web applications, microservices, or batch processing jobs. For GPU workloads, it can be leveraged in conjunction with Docker's GPU capabilities to distribute tasks across nodes with GPU hardware, though this often requires additional configuration or plugins.
