Multi-Cloud Global Content Distribution at Cloud Native Speeds

at OpenSourceSummit EU 24 @ Vienna

If you’ve been globally distributing digital content for a while, you’ll understand that merely having numerous datacenters with advanced caching patterns isn’t sufficient. When your users need to retrieve an object that’s available in different locations worldwide, they should ideally be directed automatically to the location that’s nearest and fastest for the best experience. Cloud service providers typically offer services to handle this for you within their own clouds, but what if you are running a multi-cloud or hybrid environment? K8GB is a cloud-native solution that handles GeoDNS across heterogeneous environments and enables you to reach the same level of multiregion service resilience offered by cloud providers.

k8gb meets Cluster API

at FOSDEM 24

In this talk we will be talking about an open-source way to fully automated K8s clusters that can host workloads that can survive any failure, using pure DNS as the underlying tool for switching the communication among available Kubernetes clusters. No single vendor lock-in. Workloads can be deployed in AWS, Azure, GCP, on-prem. The only common denominators are Kubernetes and Cluster-API.

A cloud native Kubernetes Global Balancer @ FOSDEM 22

k8gb is DNS based global service load balancer that can interconnect multiple Kubernetes clusters into one resilient system. Join this talk to learn how it can handle a failover scenario when pods in one cluster go down and second cluster in different location saves the situation. k8gb is an open-source Kubernetes operator that is deployed in each participating cluster. It is comprised of CoreDNS, ExternalDNS and the k8gb controller itself. Using ExternalDNS it can create a zone delegation on a common cloud DNS server like Route53 or Infoblox so that the embedded CoreDNS servers work as an authoritative DNS. K8gb controller makes sure these CoreDNS servers are updated accordingly based on the readiness probes of the application. In this sense this solution is unique, because it is using Kubernetes native tools with customisable probes and battle tested DNS protocol instead of HTTP pings or other similar approaches where single point of failure might be a problem. In k8gb architecture all k8s clusters are equal and there is no SPoF except the common edge DNS server.
