In this article, the author argues that Kubernetes needs a Long Term Release (LTS) plan in addition to keeping the current release cycle of one every 15 weeks.
Mat also cites the newly formed LTS workgroup as something to look forward to.

On average, Kubernetes nodes running on ARM instances are 20% cheaper than their AMD counterpart.
Optimising your cloud bill is tempting, but how do you seamlessly migrate existing workloads to a different architecture?
And how do you do it at scale, with more than 1500 engineers and 30 clusters in 4 regions?
In this episode of KubeFM, Thibault and Miguel explain how Adevinta built an internal platform on Kubernetes for mixed AMD and ARM workloads.
You will learn:
- The challenges they faced with validating containers for mixed architecture with a mutating webhook and the open source solution they came up with: noe.
- Building an internal platform requires careful planning and designing simple interfaces that are backwards compatible.
- How to not DDoS your container registries.

Pod Topology Spread Constraints is a convenient feature to control how pods are spread across your cluster among failure domains such as regions, zones, nodes, etc.
You can also choose the pod distribution (skew), what happens when the constraint is unfulfillable (schedule anyway vs don't) and the interaction with pod affinity and taints.
It's a great and straightforward feature, so what could possibly go wrong?
In this episode of KubeFM, you will follow Martin and his team's journey in discovering and fixing a production incident (on a Friday afternoon) due to a misconfiguration.
You will also learn:
- What are Pod Topology Spread Constraints, and how to use them?
- How unfulfillable scheduling requirements could lead to un-schedulable pods.
- How to detect and alert on unscheduled pods.
- How to manage your team during an incident to keep them calm and focused.
