About Kubernetes
- It is an open-source platform used for maintaining and deploying a group of containers
- It was introduced as a project at Google
- It was started in 2014 and it made it convenient for applications to run on the cloud
- CNCF(Cloud Native Computing Foundation) has currently maintained Kubernetes.
Benefits of Kubernetes
Portable: Kubernetes is compatible across several platforms. It is 100% open source project and thus, provide greater flexibility.
Workload Scalability: New servers are added and removed easily, it automatically changes the number of running containers, and it scales many containers manually.
Service discovery and load balancer: Kubernetes can expose a container using DNS or its IP address.If the traffic load is high , it balances load and distributes the network for deployment to be stable.
Storage orchestration: Kubernetes automatically mount storage systems like local storage and public cloud providers.
Self Healing: Kubernetes restarts containers if failed, replaces containers, kills containers that don’t respond to timely checks.
Automatic bin packing: Kubernetes specifies how much CPU and RAM each container needs.Once resources are defined, managing the resources and making decisions for them becomes easy.
Architecture of Kubernetes
About OpenShift
- Family of containerisation software products.
- Flagship product is OpenShift Container Platform.
- On-premises/cloud platform as a service (PAAS).
- Built around Linux containers.
- Orchestrated and managed by Kubernetes.
- Based on a foundation of Red Hat Enterprise Linux.
Benefits of OpenShift
Self-service provisioning: Quickly and easily create applications on demand using common tools
Control: Operations retains full control over the entire environment
Persistent storage: Allows users to run both stateful applications and cloud-native stateless applications
Polyglot, multi language support: Developers can use various languages, frameworks, and databases on the same platform
OpenShift vs Kubernetes
Car vs Engine
- Kubernetes is the engine (framework, project) that drives OpenShift
- OpenShift is the complete car (product) that takes you where you want to go
Conclusion:
OpenShift offers consistent security, default automation, and compatibility with all major cloud platforms, Kubernetes will be your go-to containerization platform if you prefer a more technical and fully controlled interface.
OpenShift is ideal for developers who want a fast, easy to use, and automated containerization, while developers can adopt Kubernetes if they want a more sophisticated, fully controllable environment.
Again, the decision is all yours.
