Which option should an administrator choose if they need to run Cloud Pak for Integration (CP4I) on AWS but do not want to have to manage the OpenShift layer themselves?
When deploying IBM Cloud Pak for Integration (CP4I) v2021.2 on AWS, an administrator has multiple options for managing the OpenShift layer. However, if the goal is to avoid managing OpenShift manually, the best approach is to deploy CP4I onto AWS ROSA (Red Hat OpenShift Service on AWS).
Why is AWS ROSA the Best Choice?
Managed OpenShift: ROSA is a fully managed OpenShift service, meaning AWS and Red Hat handle the deployment, updates, patching, and infrastructure maintenance of OpenShift.
Simplified Deployment: Administrators can directly deploy CP4I on ROSA without worrying about installing and maintaining OpenShift on AWS manually.
IBM Support: IBM Cloud Pak solutions, including CP4I, are certified to run on ROSA, ensuring compatibility and optimized performance.
Integration with AWS Services: ROSA allows seamless integration with AWS-native services like S3, RDS, and IAM for authentication and storage.
Why Not the Other Options?
B . Installer-provisioned Infrastructure on EC2 -- This requires manual setup of OpenShift on AWS EC2 instances, increasing operational overhead.
C . CP4I Quick Start on AWS -- IBM provides a Quick Start guide for deploying CP4I, but it assumes you are managing OpenShift yourself. This does not eliminate OpenShift management.
D . Terraform scripts from IBM's GitHub -- These scripts help automate provisioning but still require the administrator to manage OpenShift themselves.
Thus, for a fully managed OpenShift solution on AWS, AWS ROSA is the best option.
