In AWS EKS clusters, there are a couple of use cases for which all pods of a namespace should be automatically scheduled to specific nodes in Kubernetes, including: Clear allocation of data plane infrastructure (and costs) to teams in large organizations, Running critical workloads on on-demand nodes and not on spot nodes, or Using specific hardware, such as GPU, only by workloads that actually require it. In this post, we will explore how to facilitate that in EKS.

Velero is a tool to backup the kubernetes cluster state and its persistent volumes. It can be used for disaster recovery or cluster migration. Please refer to the official documentation for a more comprehensive description of use cases. This article describes the baseline setup for the backup to ease the start of backing up your EKS clusters.
Scaling down workloads at night or at the weekends is a common implementation task for companies building on AWS. By running only the applications that need to be available at any point in time, the total consumption of infrastructure resources can be reduced, and thus customers can benefit from the pay-by-use pricing models of cloud providers.
kube-bench is a tool for checking kubernetes clusters against requirements defined in the CIS Benchmark. The tool runs locally on a kubernetes node, performs its checks and prompts the outputs to the shell or to files. This is quite unhandy, because it means that a user needs to pick up the logs, store them somewhere and analyze them. A deployment of the tool via kubernetes can ease the process for example with the kubectl logs command, but it is still far from perfect. Luckily, there is an integration in AWS Security Hub.
Every EC2 instance type has a limited number of ENIs and IP addresses that it can use. This can quickly cause EKS to not being able to schedule more pods on a node. Luckily, there is a simple solution for that.
On the heels of the recent announcement of our consulting offer for multi-AZ block storage for EKS, it is worth discussing some of the base technologies. Let’s look into the idea and how it works under the hood.
Today we announce a new consulting offer on the AWS Marketplace: Multi-AZ Block Storage for EKS. Finally, you can use block-based storage for your specialized workloads, which is highly available.
Did you already encounter an application on EKS which does not perform well with EFS storage or which even needs dedicated block storage with multi-AZ capabilities? In this case, we have prepared something for you: We now support you with creating multi-AZ block storage for your EKS clusters and add facilities to monitor, manage and troubleshoot them with easy building blocks.
