Chapter 12. Conclusion
As can be seen from the previous chapters, the architecture of CloudForms is scalable to manage very large OpenShift Container Platform clusters.
- The role/worker/message model allows server roles to be distributed throughout CFME appliances in a region.
The appliance model allows for both horizontal and vertical scaling
- The number of worker processes can be increased on each CFME appliance (scaling out workers)
- The appliance vCPU count and memory can be increased (scaling up each appliance)
- Additional CFME appliances can be added to a region (scaling out appliances)
- The zone model allows containment of provider-specific workers, appliances and workflow processing
- The region model allows many regions to be grouped together under a single master region
CloudForms can be deployed as a VM appliance outside of OpenShift Container Platform, or running podified within the managed OpenShift Container Platform cluster itself.
