DoKC Day: KubeSphere is a multi-tenant enterprise-grade container platform with full-stack automated IT operation and streamlined DevOps workflows. It provides developer-friendly wizard web UI, helping enterprises to build out a more robust and feature-rich platform, which includes the most common functionalities needed for enterprise Kubernetes strategies. In this talk, we would like to introduce KubeSphere and its open source ecosystem. Agenda - New trend: Multi-cloud and Multi-cluster – Pain points for enterprises to implement Kubernetes in production – Introduction to the community open source ecosystem – Demo: Implementing K8s Multi-cluster and multi-cloud management – KubeSphere Community Growth: Present and Future Recording: https://www.youtube.com/watch?v=r0IGEnGrBOM&list=PLHgdNuGxrJt0ZHXZlIxDi6DTdfJbXGFo1&index=2

Agenda

5. DoKC Day Kubecon EU 2021
Most enterprises have more than two K8s clusters
New Trend: Multi-Cluster and Multi-Cloud
Multi-cloud emerged with 26%

6. Why we have so many K8s Clusters
Separate Apps and
Environments
Multiple Cloud
Providers
Company Structure
Geo Redundant,
Active-active
o Development, Testing and
Production in different
Kubernetes Cluster
o Cluster per application:
Cluster can be customized
for a kind of application
o ······
o Leverage the best
tool/service from the
different clouds
o No vendor lock-in
o High Availability
o ······
o Different department or
team owns different K8s
clusters
o Business isolation
o Multi-tenancy and security
o ······
o Provide services close to customers
o Multi-Dimension HA:
Region/AZ/Cluster/Provider
(banking, insurance, finance, live…)
o Failover, fault recovery, and
loadbalancing on multi-cluster
o ······

Complexity is the biggest challenge when adopting K8s in production
Pain Points and Challenges when adopting K8s in production
o High Learning Curve
o Kubernetes Cluster Bootstrapping
o Application Lifecycle Management
o Multi-cluster Management
o Multi-cloud management
o Security and Multi-tenancy
o Network and Storage Provision and Management
o Cloud Native Observability
o Lack of training and professional teams
