Run Containers and Kubernetes in the Cloud

Managed Kubernetes is a service such as Amazon EKS or Azure AKS, where the cloud provider runs the control layer of each cluster. Your team still looks after versions, worker nodes (the servers that run your applications), add-ons, security and the applications themselves.

Amazon EKS runs Kubernetes on AWS, and Azure AKS runs it on Azure. Both follow the same open-source Kubernetes releases, but they differ in support periods, add-ons and how they connect to each cloud’s services. The review looks at the one you use, or both.

For a small number of applications, simpler managed container services or serverless can be enough and need less upkeep. Kubernetes pays off when many teams run many services and need its flexibility. Our Build Serverless Applications on AWS and Azure use case covers the serverless option.

The Kubernetes community releases a new version roughly every four months, and each version is supported for a limited period. Plan upgrades as a regular task. Clusters defined as code make each upgrade easier to test.

AWS’s Amazon EKS version guide gives each version 14 months of standard support, then 12 months of extended support at an additional cost per cluster hour. Extended support is switched on by default. After it ends, AWS upgrades the cluster control layer automatically, but not your managed or self-managed node groups.

Microsoft’s AKS supported versions guide supports the latest minor version and the two before it. A version that drops out moves to platform support, with a 60-day grace period to upgrade. From June 2027, AKS upgrades clusters still on that version once the grace period ends. Long-term support is available if you enroll in it.

On Amazon EKS, AWS upgrades the control layer once extended support ends, or once standard support ends if extended support is switched off. Managed and self-managed node groups stay on the old version until you update them. On Azure AKS, from June 2027, AKS upgrades the whole cluster once the 60-day grace period ends, outside your maintenance window. Planning upgrades yourself keeps the timing in your hands.

On Amazon EKS, managed and self-managed node groups are not upgraded automatically when the control layer is updated, so they need their own upgrade step. We plan node upgrades as part of each version change.

Set reserved resources from measured use, switch on node autoscaling, use spare cloud capacity for work that can be interrupted and remove idle clusters. Breaking costs down by team helps people own their share.

Kubernetes places each container on a server by the resources it reserves, and actual use plays no part in that choice. When reservations are copied without measuring, servers fill up on paper while real use stays low. Comparing reserved and used resources shows the gap.

Scan images before they run, pull them only from your own private image store (registry), keep admin rights narrow, move passwords and keys into a secrets store and apply the same rules in every cluster. Our VAPT and Cybersecurity Risk Assessment solution covers wider testing.

Only the few people who run the platform should have them. Developers need access only to their own services. The review lists everyone with admin rights so you can narrow them.

The cluster’s settings, networking and add-ons are written in files kept under version control, and every cluster is built from them. A change is made once in code and reaches every cluster in the same way.

Yes. We start by reviewing them as they are, then move each one to the agreed standard in stages, with upgrades rehearsed in test first.

Write runbooks for common problems, give developers dashboards for their own services and train a second line of support. Where ongoing support is agreed, we can provide cover as well.

Standardizing environments is about making development, test and production match. This page is about running the Kubernetes platform itself: versions, security, costs and skills. Our Standardize Development, Test and Production Environments use case covers the first.

We work with AWS and Microsoft as a Technology Partner, running managed Kubernetes on Amazon EKS and Azure AKS.

The Kubernetes Review looks at your clusters’ versions, setup, security, resource use and costs, and ranks what needs attention first. It needs read-only access to your clusters, access to cost and monitoring data and time with your platform lead. We walk you through the findings on a call.
