Developers and architects can learn about AWS services like EC2, S3, Lambda, and more to build scalable, secure, and cost-effective cloud applications.

Amazon EKS managed node groups now support EC2 Auto Scaling warm pools, allowing pre-initialized EC2 instances to be kept ready for rapid scale-out. This reduces node provisioning latency for burst traffic, time-sensitive workloads, or instances with complex initialization. Warm pool instances can be configured as Stopped (cheaper, slower) or Running (costlier, faster), and reuse on scale-in is supported. The feature integrates with Cluster Autoscaler without extra configuration and is enabled via EKS API, CLI, Console, or CloudFormation. Available in all EKS regions except China.
