Introduction to Red Hat OpenShift Service on AWS

 

Red Hat OpenShift Service on AWS

 

“ROSA OCP (red hat OpenShift service on was) is a product of red hat OpenShift and amazon web services in which the CoreOS is provided by red hat and the required configuration is setup aws cloud”

                     Red Hat OpenShift Service on AWS (ROSA) is a managed service that you can use to build, scale, and deploy containerized applications with the Red Hat OpenShift enterprise Kubernetes platform on AWS. ROSA streamlines moving on-premises Red Hat OpenShift workloads to AWS, and offers tight integration with other AWS services

1.      ROSA OCP is use for the production -ready OpenShift integration to adjust workloads on aws as business needs change.

2.      -Red Hat OpenShift Service on AWS (ROSA) provides an integrated experience with OpenShift. You can use the wide range of AWS compute, database, analytics, machine learning (ML), networking, mobile, and other services to build secure and scalable applications faster.

3.      -Create a central application environment –

Basically, aws provides the platform to build a cluster and having control-plane with worker nodes. Seamlessly build, deploy, and run applications on a managed, turnkey OpenShift service with built-in runtimes, developer tools, and continuous integration and delivery (CI/CD) monitoring.

4.      Accelerate application delivery

Create standardized application components, improve configuration accuracy, and automate deployment of new applications and features.

5.      Modernize existing applications

Run cloud-based and traditional applications in one environment with a range of application frameworks, programming languages, and developer tools.

 

6.      To use this, do this following steps

1.get configuration permissions

2.download cli

3.provision the cluster

4.deploy applications

 

 

7.      All ROSA implementations will have three Master nodes in order to cater for cluster quorum and to ensure proper fail-over and resilience of OpenShift. At least two infrastructure nodes to ensure resilience  the OpenShift router layer, which provides end use application access. 

8.This should provide you with better insight into the OpenShift and AWS resources creates and how they relate to each other as well as the environments being deployed into. Allowing infrastructure and security teams to accelerate assessment and deployment of the Red Hat OpenShift Service on AWS.

9. ROSA provides two cluster deployment models: ROSA with hosted control planes (ROSA with HCP) and ROSA classic. With ROSA with HCP, each cluster has a dedicated control plane that is isolated within Red Hat’s AWS account and managed by Red Hat. With ROSA classic, cluster control plane infrastructure is hosted in the customer’s AWS account.
