Docker Swarm vs Kubernetes vs OpenShift

Docker Swarm vs Kubernetes vs OpenShift

As Modern Software application development strategy moved towards Microservices and Container-based applications. Deployment and other Operational activities in Container-based application developments are in demand with Container Orchestration and Management tools. A couple of market-leading Container Orchestration and Management tools are Docker Swarm, Kubernetes, OpenShift, Mesos and more. In this article, we will discuss the detailed comparison between Docker Swarm vs Kubernetes vs OpenShift.

Docker Swarm

Docker Swarm is one of the Containers Clustering and Scheduling tool. With this Docker Swarm, the managing cluster of Docker-based containers become easier. Because Docker Swarm is natively built to manage Docker Containers (Docker Swarm Mode). Then, Clustering is an important aspect of Microservices and Container-based applications. Because, Single container is weak, and it is very difficult to overcome the Failover and Outage.

Pros:

  • Easy to install and setup
  • Very lightweight which will run with default Docker
  • Opensource

Cons:

  • As it is using Docker API, it is limited in term of the feature.
  • Easily breakable compared to other tools

Kubernetes

Kubernetes is the tool for container-based application to automating deployment, scale and orchestrate. Then, This tool provides service discovery and load balancing, Storage Orchestration, Automated Rollback, self-healing and Configuration Management services. As of now, Kubernetes tools are widely used in big enterprises.

Pros:

  • Opensource and Big Community to support.
  • Ability to run on any operating system
  • Easy Organization

Cons:

  • Installation is a little complex
  • Dockers native features like Docker Compose are not supported.

OpenShift

Openshift is another popular Container management tool developed by RedHat. The, One of the popular flagship products of OpenShift is OpenShift Container Platform. So, This platform is an on-premises Platform as a Service built with Docker Container and the Kubernetes.

Pros:

  • Best for RedHat and its distributions
  • Opensource
  • A lot of certified Container Images for various platforms

Cons:

  • A little complex to install and setup
  • Cloud version is not available for production-ready
