Red Hat OpenShift Container Platform (self-managed)
Overall Satisfaction with Red Hat OpenShift
We have installed Openshift on bare metal servers. We are using Openshift to host our containerized applications for 5G systems. The main problems that Openshift has solved are:
- It is way simpler than Openstack so it requires less number of employees.
- It can host both containerized applications and Virtual machines which makes it a great candidate to be a common infrastructure for both legacy workloads and new workloads.
- Easiness of deployment, we can deploy the full stack completely and hardened easier than other container products
- Used to host different workloads (CNF and VNF).
- Easy to scale on both the worker and the infra layer
- Infra nodes do not require subscriptions, which means we are only paying for our workload only, and no hidden costs.
- For Openshift to be perfect, Red Hat has to follow strict life cycle timelines (i.e. as Openstack), rather than postponing a release for a few days, which will make our life easier when we plan the patching
- For Openshift to be perfect, Red Hat has to follow a strict roadmap for instance Multus Support for ODF is in Tech Preview since Openshift 4.8 and we are always getting a promise that it will be supported in the next release and it is now Openshift 4.10 and it is not supported yet, that is complicating our design work.
- Positively: I can have less silos as it can host any workload
- Negatively: Logs are not always clear, and that require longer time to troubleshoot.
Do you think Red Hat OpenShift delivers good value for the price?
Are you happy with Red Hat OpenShift's feature set?
Did Red Hat OpenShift live up to sales and marketing promises?
Did implementation of Red Hat OpenShift go as expected?
Would you buy Red Hat OpenShift again?
- Openshift is great as a common infrastructure to host both CNF and VNF.
- As until now network segregation is not possible on ODF, and the storage traffic is using the public interface, it makes the Openshift with Hyperconverged Storage not meet our security guidelines, and we are using an external CEPH, but that makes the life cycle management is a bit complicated, as we need to have 2 life cycles one for Openshift and one for CEPH.
- Logs in Openshift 4.9 are not always clear, which is making the troubleshooting a bit complicated, logs require more content.
