Amazon OpenSearch Service has enhanced Cluster Insights with two new insights — Cluster Overload and Suboptimal Sharding Strategy. Suboptimal Sharding Strategy provides instant visibility into shard imbalances that cause uneven workload distribution, while Cluster Overload surfaces elevated cluster resource utilization that can lead to request throttling or rejections. Both insights come with details of affected resources along with actionable mitigation recommendations. Previously, identifying resource constraints and shard imbalances required manually correlating multiple metrics and logs, making it difficult to detect issues early. With these new insights, you can proactively monitor cluster health and take timely action. Suboptimal Sharding Strategy detects shard imbalances caused by indices with too few shards relative to the number of data nodes, or by shards carrying disproportionately large amounts

Amazon Elastic Container Service (Amazon ECS) Managed Instances now integrates with Amazon EC2 Capacity Reservations, enabling you to leverage your reserved capacity for predictable workload availability, while ECS handles all infrastructure management. This integration helps you balance reliable capacity scaling with cost efficiency, helping achieve high availability for mission‑critical workloads. Amazon ECS Managed Instances is a fully managed compute option designed to eliminate infrastructure management overhead, dynamically scale EC2 instances to match your workload requirements, and continuously optimize task placement to reduce infrastructure costs. With today’s launch, you can configure your ECS Managed Instances capacity providers to use capacity reservations by setting the capacityOptionType parameter to reserved, in addition to the existing spot and on-demand options. You can also specify reservatio

AWS Marketplace now supports Concurrent Agreements for SaaS and Professional Services products, enabling buyers to make multiple purchases for the same product within a single AWS account. Previously, buyers could only maintain one active agreement per product per AWS account, requiring sellers to use workarounds to support expansion deals. Concurrent Agreements removes this constraint, allowing different business units to procure independently with their own negotiated terms and pricing. Both buyers and sellers benefit from the flexibility Concurrent Agreements provides. Buyers can accept multiple offers for the same product without disrupting existing agreements, supporting multi-team procurement within centralized AWS accounts, mid-term expansions, and repeat purchases. Sellers can close multi-business unit deals that couldn't happen before, transact expansions immediately instead of waiting for renewal cycles, and eliminate the operational overhead of managing workaround

Today, AWS announces the general availability of dynamic dialing mode switching for Amazon Connect Outbound Campaigns, which allows contact center administrators to change between preview and non-preview dialing modes during active campaign execution. Previously, campaigns were locked into their initial dialing mode once started, requiring administrators to stop and restart campaigns to adjust strategies. This launch solves the problem of inflexible dialing strategies that couldn't adapt to real-time business needs and agent availability changes. Dynamic dialing mode switching enables contact centers to optimize agent productivity and campaign efficiency in real-time without campaign interruptions. For example, you can automatically switch from progressive dialing to preview mode when handling high-priority contacts that require additional context, then revert back when traffic returns to normal patterns. This flexibility is particularly valuable for campaigns with varying c

Amazon CloudWatch Database Insights now provides lock contention diagnostics for Amazon RDS for PostgreSQL instances. This feature helps you identify the root cause behind both ongoing and historical lock contention issues within minutes. The lock contention diagnostics feature is available exclusively in the Advanced mode of CloudWatch Database Insights. With this launch, you can visualize a locking condition in the Database Insights console, which shows the relationship between blocking and waiting sessions. The visualization helps you quickly identify the dominating sessions, queries, or objects causing lock contention. Additionally, this feature persists historical locking data for 15 months, allowing you to analyze and investigate historical locking conditions. You no longer need to manually run custom queries or rely on application logs to diagnose lock contention issues, streamlining the troubleshooting process. You can get started with this feature by enabl

Today, we're announcing the general availability of AWS Security Hub Extended, a new plan that extends unified security operations across your enterprise through a single-vendor experience. This plan helps address the complexity of managing multiple vendor relationships and lengthy procurement cycles by bringing together the best of AWS detection services and curated partner security solutions. The Security Hub Extended plan delivers three critical advantages. First, it helps streamline procurement by consolidating solution usage into one bill—thereby reducing procurement complexity while preserving direct access to each provider's domain expertise. AWS Enterprise Support Customers also benefit from unified Level 1 support from AWS. Second, it enables you to establish more comprehensive protection by bringing together the best of AWS detection services with curated partner solutions across endpoint, identity, email, network, data, browser, cloud, AI, and security operatio

Amazon Cognito enhances client secret lifecycle management for app clients of Cognito user pools by adding client secret rotation and support for custom client secrets. Cognito helps you implement secure sign-in and access control for users, AI agents, and microservices in minutes, and a Cognito app client is a configuration that interacts with one mobile or web application that authenticates with Cognito. Previously, Cognito automatically generated all app client secrets. With this launch, in addition to the automatically generated secrets, you have the option to bring your own custom client secrets for new or existing app clients. Additionally, you can now rotate client secrets on-demand and maintain up to two active client secrets per app client. The new client secret lifecycle management capabilities address needs for organizations with periodic credential rotation requirements, companies improving security posture, and enterprises migrating from other authentication sys

AWS is announcing the general availability of Amazon EC2 Storage Optimized I8g.metal-48xl instances. I8g instances are powered by AWS Graviton4 processors that deliver up to 60% better compute performance compared to previous generation I4g instances. I8g instances use the latest third generation AWS Nitro SSDs, local NVMe storage that deliver up to 65% better real-time storage performance per TB while offering up to 50% lower storage I/O latency and up to 60% lower storage I/O latency variability. These instances are built on the AWS Nitro System, which offloads CPU virtualization, storage, and networking functions to dedicated hardware and software enhancing the performance and security for your workloads. Amazon EC2 I8g instances are designed for I/O intensive workloads that require rapid data access and real-time latency from storage. These instances excel at handling transactional and real-time databases, including MySQL,
