# Containers

Deploy applications consistently across environments

## **Kubernetes** 

* IBM Cloud has a managed Kubernetes service that removes the complexity of deploying and upgrading a Kubernetes cluster. Clusters can be provisioned with a variety of CPU and RAM specifications and deployed to any IBM Cloud data center. 
* The IBM Cloud Container Registry is a multi-tenant image registry.  

To read more about Kubernetes check out “[What is Containers-as-a-service (CaaS)?](https://www.ibm.com/services/cloud/containers-as-a-service)” on IBM Cloud.

{% hint style="info" %}
Kubernetes is an open-source container orchestration project. Containers provide process isolation. Containers are fundamental to creating cloud-native microservice-based applications. 

Kubernetes (or k8s) is a container orchestration system for automating application deployment, management and scaling. Kubernetes coordinates computing, networking, and storage infrastructure for user workloads.

## **OpenShift** 

* IBM Cloud has a managed OpenShift service that removes the complexity of deploying and upgrading an OpenShift cluster. Clusters can be provisioned with a variety of CPU and RAM specifications and deployed to any IBM Cloud data center. 
* OpenShift 4 brought in many new services to improve developing cloud native applications, including service mesh, serverless computing, and pipelines.

{% hint style="info" %}
The RedHat OpenShift platform overlays a set of opinionated processes, automation, and additional capabilities on top of Kubernetes.

OpenShift is an open-source project that extends core Kubernetes functionality with its own opinions and abstractions.
