Session 1: The State of Multi-tenancy in Kubernetes
https://www.vcluster.com/blog/underst...
In this session, you'll explore the current landscape of Kubernetes multi-tenancy options. You'll learn about different approaches to multi-tenancy, their pros and cons, and how to choose the right solution for your specific use case. You will also see a comparison of tools such as vCluster, Capsule, Kamaji, kcp, k3k.
What You Will Learn:
Overview of Kubernetes multi-tenancy concepts
Comparison of soft multi-tenancy vs. hard multi-tenancy (and everything in between)
Evaluation of namespace-based, virtual cluster, and dedicated cluster approaches
Criteria for selecting the most appropriate multi-tenancy strategy
Comparison of tools such as vCluster, Capsule, Kamaji, kcp, k3k.
We can't wait to see you there!
