この日は MCP 仕様の大型改訂への対応が注目点でした。Model Context Protocol が 2026-07-28 仕様を公開し、ローンチ以来最大の改訂として MCP がステートレス化され統制された拡張の仕組みが導入されたことを受け、AgentCore Gateway がどう対応するかが解説されています。あわせて LangGraph によるワークフロー編成と Strands によるエージェント推論を組み合わせ、AgentCore 上に本番品質のマルチエージェント市場監視システムを構築する手順も公開されました。セキュリティでは KMS と CloudHSM の使い分けの指針、npm と PyPI からのパッケージ更新を Amazon Linux 上で安全に行う方法 (公開直後の数時間が最も危険であるという観点) が示されています。オーストラリア向けには 2026 Phase 1a の IRAP レポートが AWS Artifact で提供開始となりました。サービス更新は EKS Provisioned Control Plane の HPA 同期並列度向上によるポッドオートスケーリング高速化、IAM Identity Center ディレクトリのマルチリージョン対応などです。

AWS What's New

AWS Console Home now supports the Cost and Usage widget in the AWS European Sovereign Cloud (Germany) Region

AWS Console Home now supports the Cost and Usage widget in the AWS European Sovereign Cloud (Germany) Region, allowing customers to surface insights from Cost Explorer and Cost Optimization Hub on their Console Home dashboard.

With the Cost and Usage widget, customers can track month-to-date and forecasted costs, identify savings opportunities, and see how their spend breaks down by service over time.

To get started, sign in to the AWS Management Console, select Add widgets, and drag the Cost and Usage widget onto your Console Home dashboard. To learn more, see Working with widgets in AWS Console Home documentation.

Second-generation AWS Outposts racks now supported in the AWS Asia Pacific (Mumbai) Region

Second-generation AWS Outposts racks are now supported in the Asia Pacific (Mumbai) Region. Outposts racks extend AWS infrastructure, AWS services, APIs, and tools to virtually any on-premises data center or colocation space for a truly consistent hybrid experience.

Organizations from startups to enterprises and the public sector in and outside of India can now order their Outposts racks connected to this new supported region, optimizing for their latency and data residency needs. Outposts allows customers to run workloads that need low latency access to on-premises systems locally while connecting back to their home Region for application management. Customers can also use Outposts and AWS services to manage and process data that needs to remain on-premises to meet data residency requirements. This regional expansion provides additional flexibility in the AWS Regions that customers’ Outposts can connect to.

To learn more about second-generation Outposts racks, read this blog post and user guide. For the most updated list of countries and territories and the AWS Regions where second-generation Outposts racks are supported, check out the Outposts rack FAQs page.

Amazon EKS Provisioned Control Plane now delivers faster pod autoscaling

Amazon EKS now delivers faster pod autoscaling across all Provisioned Control Plane clusters by increasing Horizontal Pod Autoscaler (HPA) sync concurrency to up to 40 times the default Kubernetes value. This reduces the time it takes for HPA-driven workloads to scale in response to increased load, enabling faster responsiveness to demand.

The Kubernetes Horizontal Pod Autoscaler (HPA) continuously monitors workload metrics and adjusts pod counts to match demand. In clusters running hundreds or thousands of HPA objects, the speed at which the Kubernetes control plane processes these objects determines how quickly workloads scale in response to changing demand. The HPA sync concurrency setting controls how many HPA objects the control plane evaluates in parallel. By increasing this value, Provisioned Control Plane clusters now process more HPA objects simultaneously, reducing the time between detecting increased load and scaling out pods.

This enhancement is available to all customers using EKS Provisioned Control Plane and requires no configuration changes. To learn more about this enhancement, see EKS Provisioned Control Plane in the EKS User Guide.

AWS IAM Identity Center extends multi-Region support to Identity Center directory

詳細を表示

IAM Identity Center helps you configure the single sign-on experience of your workforce to AWS accounts and applications. You can now replicate IAM Identity Center from the primary AWS Region where you first enabled it to additional Regions of your choice when using Identity Center directory as your identity source. This extends the multi-Region support capability, previously available for Identity Center organization instances connected to external identity providers, to instances that use the Identity Center directory to manage and authenticate their workforce. This feature enhances resilience of user access to AWS accounts and helps you deploy AWS applications in the AWS Regions that best align with your business needs such as application data residency and proximity to users.

When you enable this feature, IAM Identity Center automatically replicates your identities, entitlements, and other information from the primary Region to additional Regions. If IAM Identity Center is affected by a disruption in the primary Region, IAM Identity Center users continue to have access to their AWS accounts using the already provisioned entitlements in the additional Regions. 

AWS application administrators can use the standard application deployment workflow to deploy their application in an additional Region while you continue to administer IAM Identity Center in the primary Region.

IAM Identity Center multi-Region support is currently available in the 17 enabled-by-default commercial AWS Regions for organization instances of IAM Identity Center. The IAM Identity Center organization instance must be configured with a multi-Region customer managed KMS key (CMK). To find out which AWS applications support deployment in additional Regions, visit AWS applications that you can use with IAM Identity Center. Standard AWS KMS charges apply for storing and using CMKs. IAM Identity Center is provided at no additional cost. To learn more about IAM Identity Center, visit the product detail page. To get started, see the IAM Identity Center User Guide.

Amazon EFS now supports cross-account Replication in AWS GovCloud (US)

Amazon EFS now supports cross-account Replication in AWS GovCloud (US), allowing customers to replicate file systems between AWS accounts. EFS Replication enables you to easily maintain an up-to-date replica of your file system in the AWS GovCloud (US) Region of your choice. With this launch, EFS Replication customers can meet business continuity, multi-account disaster recovery, and compliance requirements by automatically keeping replicas of their file data in separate accounts. 

Customers often use multiple AWS accounts to help isolate and manage business applications and data for operational excellence, security, and reliability. Starting today, you can use EFS Replication to replicate your file system to another account in any AWS GovCloud (US) region. This eliminates the need to set up custom processes to synchronize EFS data across accounts, enhancing resilience and reliability in distributed environments. 

To learn more, visit the Amazon EFS documentation and get started by configuring EFS Replication in just a few clicks using the Amazon EFS Console, AWS CLI, AWS CloudFormation, and APIs.

Amazon Connect Customer now automatically finds example agent evaluations for tailored coaching

Amazon Connect Customer now automatically surfaces relevant examples of an agent's evaluations when managers are preparing coaching feedback, so they can deliver actionable, evidence-backed coaching to agents. When a manager prepares agent coaching feedback in Amazon Connect Customer, they automatically receive examples of recent evaluations where the agent scored high or low on the chosen coaching topic, along with human or AI evaluator notes explaining the agent behaviors that drove the result. For example, while preparing feedback for an agent on "de-escalation," a manager receives example calls where the agent successfully calmed a frustrated customer, alongside calls that were escalated, with insights into the agent behaviors that led to each outcome. This enables managers to deliver tailored coaching that accelerates agent performance improvement, while saving the time spent manually searching for examples.

This feature is available in all regions where Amazon Connect Customer is offered. To learn more, please visit our documentation and our webpage
