Amazon Elastic Kubernetes Service now offers a 24 GB etcd database on its 4XL and 8XL provisioned control‑plane tiers. etcd stores all cluster state, so the bigger size lets clusters hold more pods, jobs, events and custom resources. The change applies to clusters running EKS version 1.34 or later and is rolled out automatically to existing 4XL and 8XL clusters. The larger database is available in every commercial AWS Region where the provisioned control plane is offered.

## The facts

- 24 GB etcd database, up from 16 GB
- Available on 4XL and 8XL tiers for EKS version 1.34+

## Why it matters

Enterprises running large AI/ML or CI/CD workloads can avoid hitting etcd limits and keep scaling without downtime.
