Service meshes and the community's opinion of them have changed drastically over the years.
From being perceived as unnecessary, complicated and bloated, they matured into security and observability powerhouses (while still retaining much of their complexity).
In this KubeFM episode, William deep dives into the world of service meshes and explains a few of the technical choices and trade-offs of service meshes in simple terms.
You will learn:
- What is a service mesh and its design (i.e. control plane and data plane).
- How Ambient mesh departs from the traditional sidecar model and how it affects reliability and security.
- Why there's more than just eBPF in sidecarless service meshes and the limitation of this technology.
- The direct costs (compute) and human factors involved in operating a service mesh.

Kubernetes: 50 namespaces vs 50 control planes vs 50 clusters.
For the last episode of "Building Kubernetes platforms", we decided to run an experiment: how much does multi-tenancy cost?
We created three scenarios:
- 50 tenants using the Hierarchical Namespace Controller.
- 50 tenants using vCluster.
- 50 dedicated clusters managed via Karmada.
Which one was the most expensive?
Spoiler: the dedicated clusters are very expensive.
But is it worth the investment?
Chris will cover it live on Thursday!

Kubernetes namespaces are the basic building block for identity and isolation but don't provide any of those features out of the box.
In this session, you will explore in a great level of detail:
- How namespaces are (not) used during scheduling.
- How namespaces are (not) used in the cluster network and the implementation of Network Policies.
- How namespaces provide the starting point for RBAC.
The insights will help you understand the trade-offs in designing a multi-tenant platform on Kubernetes.

Can you run databases on Kubernetes and survive to tell the story?
Or should you refrain from running stateful workloads as much as possible?
In this KubeFM episode, Steven argues that you should run databases on Kubernetes.
He also goes further and demonstrates how to build your custom operator to manage your database.
Listen to the episode and learn how:
- You can use Kubebuilder and the Operator Framework to build your operator.
- Custom Resources lets you create higher abstractions to manage your infrastructure as code.
- Steven's operator manages hundreds of databases at scale at QuestDB.

Structured Authentication Config is the most significant Kubernetes authentication system update in the last six years.
In this KubeFM episode, Maksim explains how this is going to affect you:
1. You can use multiple authentication providers simultaneously (e.g., Okta, Keycloak, GitLab) ā no need for Dex.
2. You can change the configuration dynamically without restarting the API server.
3. You can use any JWT-compliant token for authentication.
4. You can use CEL (Common Expression Language) to determine whether the token's claims match the user's attributes in Kubernetes (username, group).
