- Managed Kubernetes Price Comparison
"TL;DR: Azure and Digital Ocean don’t charge for the compute resources used for the control plane, making AKS and DO the cheapest for running many, smaller clusters. For running fewer, larger clusters GKE is the most affordable option. Also, running on spot/preemptible/low-priority nodes or long-term committed nodes makes a massive impact across all of the platforms."

- How to Optimize I/O Intensive Containers on Kubernetes
"Understanding how the Linux operating system schedules tasks and allocates CPU time to tasks can help application developers optimize containers which are highly threaded and I/O intensive."
- Vault replication across multiple datacenters on Kubernetes
Banzai cloud explains how to create a geo-distributed Vault cluster capable of surviving region or AZ outages, with their Bank-Vaults Vault operator.
- How OpenEBS Brings Container Attached Storage to Kubernetes
“Container Attached Storage enables Kubernetes users to treat storage entities as microservices. CAS has two elements — the control plane and the data plane. The control plane is deployed as a set of Custom Resource Definitions (CRD) that deal with the low-level storage entities. The data plane runs as a collection of Pods close to the workload.”
