Docker Swarm is designed to provide native clustering and orchestration capabilities for Docker containers. This means that it allows you to manage a cluster of Docker hosts as a single virtual system, facilitating the deployment, scaling, and management of applications within containers.

With Docker Swarm, you can easily create and manage services that run replicated containers across multiple nodes in the cluster. Swarm handles load balancing automatically, ensuring that traffic is distributed across the different container instances. It also provides high availability by allowing containers to be managed across multiple hosts, meaning that if one host goes down, the services can still be available on other hosts.

The other options relate to different functionalities that are not inherent to Docker Swarm. For instance, resource allocation for virtual machines is more relevant to traditional VM orchestration tools rather than container orchestration. Automated testing of applications typically occurs in a CI/CD pipeline and is not a feature offered specifically by Docker Swarm. Lastly, version control for images is handled by Docker's image management capabilities but does not fall under the orchestration umbrella provided by Swarm.
