Kubernetes Cluster Federation | Quick Guide

Introduction to Kubernetes Federation

• Kubernetes cluster configured in any region on any Cloud platform like AWS, Microsoft Azure, and Google Cloud.
• Kubernetes Federation manages deployments and services across all the clusters located in different areas.

• Synchronizing resources across clusters
• Cross-cluster discovery

Challenges for Kubernetes Cluster Adoption

• Cannot access Federation cluster if it gets down, cannot access Federation until it gets up back.
• In case failure of Federation Cluster, every Kubernetes Cluster will act as an independent Cluster.
• Alerting and Auditing across Federated Kubernetes Clusters.

Solution Offerings for Setting up Kubernetes Cluster Federation

• Kubernetes Cluster runs on different Clouds and in different regions managed and controlled by using Kubernetes Federation control plane.
• Kubernetes Federation control plane shares the resources across the cluster and keeps in sync which minimizes the cluster failure chances across the cluster.
• Kubernetes Federation provides high availability by sharing load across the cluster using DNS service and load balancers.

Multi-Region Kubernetes Cluster Management

• Create New Kubernetes Cluster enabling preemptive node features.
• Get static IP from Google Compute Engine.
• Kubernetes YAML is defining multiple Kubernetes objects involving autoscaling.
• Continuous Delivery Pipeline
• The configuration of GEO-Domain Name Server
• After activation, create two pools using static IP
• Create a monitor and finally the load balancer that distributes load based on visitor geolocation.

• Geographically Distributed Deployments
• Hybrid Cloud extending deployments from on-premises cluster to Cloud
• Higher Availability
• Application Migration
• Resilience from Single zone failure
• Zero downtime master upgrades
• Reduced downtime from master failures
• Sync Resources across clusters
• Cross-Cluster delivery
• Fault Isolation
• Scalability

• Global Scheduling
• Automated Recovery from datacenter failures
• Avoids vendor Lock-In
• Federation can keep resources in multiple clusters in sync.
• Federation provides high availability by spreading the load across clusters and auto-configuration of load balancers, minimizing the impact of a cluster failure.
• Federation provides Hybrid Cloud capabilities of Kubernetes Clusters running in different Cloud providers.
