Amazon EKS managed node groups introduces new update strategies

By

Amazon Elastic Kubernetes Service (Amazon EKS) now offers new update strategies for managed node groups, giving you control over how Amazon EC2 instances in your clusters are updated with new configurations or for new Kubernetes versions. This feature provides flexibility to make changes to your Amazon EKS cluster nodes in a way that best suits your use case, while reducing operational overhead and compute costs.

Amazon EKS managed node group update strategies let you choose between the current EKS managed node group update behavior, Default, and a new strategy, Minimal Capacity, that attempts to update the managed node group by launching fewer new EC2 instances compared to the Default strategy. Minimal Capacity is useful for managed node groups that have been scaled to zero, are using EC2 instances in high demand, or instances with limited availability. This is especially beneficial, for example, if your managed node groups have GPU-accelerated instances or instances purchased using a capacity reservation like Reserved Instances. By default, both existing and new EKS managed node groups use the “Default” update strategy, which updates managed node groups in the same way as before this launch.

EKS managed node group update strategies is available today at no additional cost in all AWS Regions , except AWS GovCloud (US) and China Regions.

AWS now supports Zone Groups for Availability Zones

By

AWS now supports the Zone Groups for Availability Zones across all AWS Regions, making it easier for you to differentiate groups of Local Zones and Availability Zones.

Zone Groups were initially launched to help you identify related groups of Local Zones that reside in the same geography. For example, the two interconnected Local Zones in Los Angeles (us-west-2-lax-1a and us-west-2-lax-1b) make up the us-west-2-lax-1 Zone Group. These Zone Groups are used for opting in to the AWS Local Zones.

You can now find the Zone Group for Availability Zones for all Regions in the DescribeAvailabilityZones API. For example, the Availability Zones in the US West (Oregon) Region make up the us-west-2-zg-1 Zone GroupName, where us-west-2 indicates the Region, and zg-1 indicates it is the group of AZs in the Region. This new identifier (such as us-west-2-zg-1) has replaced the previous naming (such as us-west-2).

For more details, please refer to the Zone Group for Availability Zones blog post and the visit DescribeAvailabilityZones API documentation.
