In the previous chapter, we briefly touched upon OpenShift HA and high availability (HA) in general. We discussed how OpenShift provides redundancy in case of a failure and how you can prevent this from happening by designing your OpenShift cluster properly. Finally, we finished the chapter with backup and restore methods and procedures in OpenShift.
In this chapter, we are going to talk about OpenShift scenarios in single and multiple data centers. This chapter will also explain how to properly design OpenShift in a distributed and redundant configuration across one or more data centers.
After reading this chapter, you will have an understanding of the following topics:
- OpenShift single-DC HA design
- OpenShift multi-DC HA design
