## What it is
K8GB (Kubernetes Global Balancer) is a CNCF Incubating, open-source global server load balancing (GSLB) solution for Kubernetes, implemented as a Kubernetes operator in Go. It load-balances traffic across geographically dispersed Kubernetes clusters using DNS-based strategies (failover, round-robin, weighted) configured via a single Gslb CRD, with integrations for Route53, Infoblox, Cloudflare, NS1, Azure DNS, and RFC2136-compatible DNS servers.

## Use cases
- load balance traffic across multiple Kubernetes clusters in different regions
- configure DNS failover between primary and secondary Kubernetes clusters for high availability
- replace proprietary hardware GSLB appliances with a cloud native solution
- enable global load balancing for a Kubernetes Ingress using a single CRD
- use Kubernetes liveness and readiness probes to drive global traffic routing decisions
- set up multi-cluster DNS-based load balancing with Route53 or Cloudflare
- avoid a single point of failure in global load balancing without a dedicated management cluster

## When to choose
- you run Kubernetes workloads across multiple geographic regions or clusters and need DNS-based global load balancing
- you want a Kubernetes-native GSLB managed via CRDs and Helm instead of proprietary network vendor appliances
- you need region failover, round-robin, or weighted round-robin strategies driven by Kubernetes health probes
- you use Route53, Infoblox, Cloudflare, NS1, Azure DNS, or RFC2136-compatible DNS providers
- you want an open-source, CNCF-governed solution with no single point of failure

## When to avoid
- you only need load balancing within a single Kubernetes cluster (a standard Service or Ingress controller suffices)
- you need layer-4/layer-7 proxying or traffic splitting at the request level rather than DNS-level routing
- your environment cannot use or expose DNS as the traffic steering mechanism
- you require latency-based routing with sub-second failover, since DNS TTLs introduce propagation delays
- you are not running Kubernetes, as k8gb is tightly coupled to the Kubernetes ecosystem
