**AWS Weekly Roundup: OpenSearch, Valkey, and Key Launches**
Last week was another exciting week in the world of AWS and open source! The OpenSearch and Valkey teams made a significant impact at the Open Source Summit Korea 2026 and MCP DevSummit Seoul 2026, while AWS itself rolled out several key updates and new services. This article summarizes the major highlights, including community engagement, critical new features, and upcoming events.
### Key Open Source Community Engagement
The OpenSearch and Valkey teams traveled to Seoul to actively engage with the open-source community. They participated in the Open Source Summit Korea 2026 and MCP DevSummit Seoul 2026, fostering collaboration and knowledge sharing among developers and contributors. This presence aimed to push these vital open-source projects forward and strengthen their respective user groups.
**OpenSearch: Enhanced Search and Observability**
OpenSearch, the open-source, enterprise-grade search and observability suite, continues to evolve. A major recent milestone was the release of **OpenSearch 3.7**. This version introduces powerful new tools designed to:
* Query, alert, and track Service Level Objectives (SLOs) across logs, traces, and metrics through a single, unified interface.
* Retrieve vectors up to **5.5x faster**, significantly boosting search performance for vector-based applications.
Following this release, Amazon OpenSearch Service now supports OpenSearch 3.7, providing users with immediate improvements in vector search performance, search relevance, and Query Insights.
**Valkey: High-Performance Data Management**
Valkey, the high-performance in-memory data structure store, also saw a major update with **Valkey 9.1**. Key enhancements in this version include:
* A redesigned I/O threading model that improves throughput by up to **17%**.
* Reduced memory usage for strings under 128 bytes by up to **20%**.
Consequently, Amazon ElastiCache now supports Valkey 9.1 for node-based clusters. This delivers higher throughput, better memory efficiency, and stronger access control, making it ideal for multi-tenant workloads.
### Recent AWS Service Launches and Updates
Beyond the open-source community events, AWS announced several important service updates and new offerings:
* **Amazon EC2 Application Status Checks:** A new status check helps detect and respond to application-level issues on EC2 instances, such as a web server stopping requests or a Docker daemon failing.
* **AWS IAM Role Manager:** This new feature automatically sets up the IAM roles required by AWS services. It can create a default role or reuse a compatible existing one, streamlining the setup for services like consoles.
* **OpenAI Daybreak on Amazon Bedrock:** Eligible customers can now access Daybreak, OpenAI’s cyber defense initiative. It provides governed access to frontier AI for security tasks, available as Daybreak Blue (powered by GPT-5.6 Sol) and Daybreak Red (powered by a new GPT-5.6 Cyber model).
* **New Foundation Models in Amazon SageMaker JumpStart:** The portfolio of available models has expanded with new foundation models designed for specific enterprise AI challenges.
### Other Notable AWS News
* **ACM Email Validation Deprecation:** Support for email-validated public certificates in AWS Certificate Manager will end on **September 30, 2027**. Users must migrate to DNS validation before this date.
* **Next-Generation AWS VPN Client:** A new client, built on OpenVPN3, offers full backward compatibility with existing endpoints while introducing automation and security features for enterprise networking teams.
* **Oracle Exadata on Exascale (ExaDB-XS) on AWS:** This new offering brings Exadata-class performance and availability through a consumption-based model, allowing for independent scaling of compute and storage.
### Upcoming Opportunities to Connect
You can meet the OpenSearch and Valkey teams in person at their respective events. Networking and collaboration are key to the open-source ecosystem’s strength.

### FAQ
**Q1: What is OpenSearch used for?**
A1: OpenSearch is an open-source suite for search, analytics, observability, and dashboards. It helps organizations bring order to unstructured data at scale, enabling powerful search capabilities and operational insights.
**Q2: What are the main benefits of the new OpenSearch 3.7?**
A2: OpenSearch 3.7 allows for faster vector retrieval (up to 5.5x) and provides integrated tools to monitor and alert on SLOs across logs, metrics, and traces from a single interface.
**Q3: What is Valkey, and how is it different from Redis?**
A3: Valkey is an open-source, high-performance in-memory data structure store. It is a community-driven fork of Redis, focusing on performance, security, and stability, while also introducing new features and improvements like those in version 9.1.
**Q4: What is the AWS IAM Role Manager?**
A4: The IAM Role Manager automatically creates and manages the IAM roles needed by AWS services. When you set up a supported service, it either creates a new role or reuses an existing one that matches the required permissions, simplifying initial setup.
**Q5: When will email validation for ACM certificates no longer be supported?**
A5: Email validation for public certificates in AWS Certificate Manager will be discontinued on **September 30, 2027**. You must migrate to DNS validation by that date.
