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.

To learn more and get started, visit the Amazon EKS product page or Amazon EKS User Guide for managed node groups .
 

Today, Amazon Web Services (AWS) is announcing the general availability of AWS Managed Notifications in the AWS Console Mobile Application. You can now get push notifications for default AWS Health notifications and view them in the AWS Console Mobile Application’s notification inbox, alongside your user-configured notifications such as CloudWatch alarms.

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.
 

Amazon Web Services (AWS) is announcing the general availability of AWS Managed Notifications, a new feature of AWS User Notifications that enhances how customers receive and manage AWS Health notifications. This feature allows you to view and modify default AWS Health notifications in the Console Notifications Center, alongside your custom notifications such as CloudWatch alarms.

A dedicated user interface is now available to manage notification subscriptions, including the ability to unsubscribe the primary or alternate contact emails from specific notification categories like ‘Operational events’. You can easily subscribe to Health Notifications through additional delivery channels.

AWS announces the general availability of Amazon S3 Metadata, the easiest and fastest way to discover and understand your Amazon S3 data. S3 Metadata provides automated and easily queried metadata that updates in near real time, simplifying business analytics, real-time inference applications, and more. S3 Metadata supports object metadata, which includes system-defined details like size and the source of the object, and custom metadata, which allows you to use tags to annotate your objects with information like product SKU, transaction ID, or content rating.

S3 Metadata automatically captures metadata from objects as they are uploaded into a bucket and makes that metadata queryable in a read-only table. As data in your bucket changes, S3 Metadata updates the table within minutes to reflect the latest changes. These metadata tables are stored in Amazon S3 Tables, storage optimized for tabular data. The S3 Tables integration with AWS Glue Data Catalog is in preview, allowing you to stream, query, and visualize data—including S3 Metadata tables—using AWS analytics services such as Amazon Athena, Amazon Data Firehose, Amazon EMR, Amazon QuickSight, and Amazon Redshift. Additionally, S3 Metadata integrates with Amazon Bedrock, allowing for the annotation of AI-generated videos with metadata that specifies its AI origin, creation timestamp, and the specific model used for its generation.

S3 Metadata is available in the following AWS Regions: US East (N. Virginia), US East (Ohio), and US West (Oregon).

For pricing details, visit the Amazon S3 pricing page . To learn more, visit the Amazon S3 Metadata overview page , documentation , and AWS News Blog .
