Building and Scaling Kubernetes Platforms

In the first part of this series we are going to take a look at some of the considerations when building out a Kubernetes Platform. We will discuss Flexibility, Security, and Cost Efficiency.

• Flexibility: Choose between cloud or on-prem, DIY solutions, and use of namespaces/vClusters for user isolation.
• Security: Balance productivity and security, start with simple steps, and invest in RBAC.
• Cost Efficiency: Optimize cluster numbers, compare hosted vs. DIY, and manage costs effectively.
• Overall: Evaluate deployment options, prioritize security, optimize costs, and ensure user isolation.

Now that you support more users on your Kubernetes Platform, how do you scale cost-effectively? Should you use a single cluster and split it up, or create multiple clusters for different use cases?

• Single Cluster: Use a multi-cluster platform within a single cluster for cost optimization and easier management.
• Multiple Clusters: Assign dev/test/preview environments to separate clusters for regional control and minimal platform management.
• Production vCluster: Use vClusters in production for scalability and isolation across single or multi-cluster setups.
• Overall: Decide on single vs. multiple clusters, manage regional control, ensure scalability, and optimize for cost and management.
