Most common different between Docker Swarm and Open Shift

OpenShift and Docker Swarm are both container orchestration platforms, but there are several differences between them.

1. Architecture: OpenShift is built on top of Kubernetes, which is a popular container orchestration platform, while Docker Swarm is built directly into the Docker engine. This means that OpenShift provides more features and functionality than Docker Swarm, but it also requires more resources to run.

2. Multi-tenancy: OpenShift provides more advanced support for multi-tenancy, allowing you to set up multiple projects with their own resources, quotas, and access controls. Docker Swarm, on the other hand, provides a simpler approach to multi-tenancy with basic namespace isolation.

3. Security: OpenShift provides several security features, such as role-based access control (RBAC), network policies, and encrypted communication between components. Docker Swarm also provides some security features, but they are not as comprehensive as those provided by OpenShift.

4. Integration: OpenShift provides better integration with third-party tools and services, such as Jenkins, Git, and logging and monitoring tools. Docker Swarm provides some integration with these tools, but it’s not as seamless as it is with OpenShift.

5. Support: OpenShift is a product of Red Hat, a well-established enterprise software company, and it provides enterprise-level support for its customers. Docker Swarm, on the other hand, is an open-source project with less formal support options.

In summary, while both OpenShift and Docker Swarm provide container orchestration capabilities, OpenShift provides more advanced features and functionality, better support for multi-tenancy and security, and better integration with third-party tools and services. Docker Swarm, on the other hand, is simpler to set up and run and may be a better choice for smaller deployments or organizations that prioritize simplicity over advanced features.
