Hands-On Microservices with Kubernetes

Federation

Managing a single large Kubernetes cluster is not simple. Managing multiple geo-distributed clusters is much harder. It is especially difficult if you try to treat multiple clusters as one big logical cluster. Many challenges arise around high availability, fail-over, load balancing, security, and latency.

For many very large systems, multiple clusters are a necessity. Sometimes, it is necessary for smaller systems too. The following are some use cases:

• Hybrid on-premises/cloud
• Geo-distributed redundancy and availability
• Multi-provider redundancy and availability
• Very large systems (more nodes than a single Kubernetes cluster can handle)

Kubernetes attempted to address the problem with the Kubernetes Federation V1 proposal and ...
