CoreOS rkt / Container Linux (project ended) vs Red Hat OpenShift on IBM Cloud

Likelihood to Recommend

CoreOS rkt is well suited for any development environment where operating systems and hardware are not homogeneous. CoreOS rkt allows us to write code on one machine with the confidence that it will work on any other. This has been immensely helpful as our developers are often switching to the latest and greatest machines and operating systems. CoreOS rkt is less suited for environments that are not Software as a Service. There is often no need to bring the entire developer environment and associated dependencies when delivering a one time product. In these environments CoreOS rkt just adds unneeded overhead.

OpenShift is well suited if you want to use docker and [Kubernetes] but you want to hide the complexity of these two technologies. It gives a developer much more freedom in terms of code deployment, builds process, and implementation. One of its strengths is scaling and you can easily configure it for each application.

We are using IBM Cloud App ID as a simple method to get an OIDC provider for our applications, that are running within the OpenShift cluster. Also, IBM Cloud Object Storage is used within the workload to store data via an s3 compliant way. The IBM Cloud Container Registry is an easy way to store the container images, that are used within the OpenShift cluster. Especially we configured the system in such a way to stop the image delivery if the container images are vulnerable. IBMs Cloud Pak for Integration and Business Automation is providing a rich feature set, that is tackling a lot of use-cases. They are both installable in the provided cluster easily.
