Introducing the next generation of Amazon OpenSearch Serverless for building your agentic AI applications | Amazon Web Services

Amazon’s next-generation OpenSearch Serverless is a managed search and vector engine optimized for agentic AI applications. It scales from zero to thousands of requests per second, creates resources in seconds, and can reduce costs by up to 60% compared with clusters provisioned for peak demand. The release is generally available across supported AWS commercial Regions and integrates with tools such as Vercel, Kiro, Claude Code, and Cursor. ## Elastic Scaling and Cost Optimization - Scales capacity up to 20 times faster than the previous generation. - Supports scale-to-zero when idle, minimizing compute costs. - Charges separately for compute through OpenSearch Compute Units (OCUs), storage in GB-month, and GPU acceleration where applicable. - Supports capacity limits for indexing and search, with minimum capacity set to zero and configurable maximums. ## Creating Next-Generation Collections - Collections can be created through the Amazon OpenSearch Service console, AWS CLI, or SDKs. - The console’s **Express create** option automatically applies default settings and matching security policies. - At launch, supported collection types are: - Full-text search (`SEARCH`) - Vector search (`VECTORSEARCH`) - Users who need the existing infrastructure can select the classic OpenSearch Serverless generation. - Collections inherit their generation from a parent collection group. Example CLI workflows create a next-generation collection group with standby replicas and then create a search collection within it. ## Integrations for Agent Development - Vercel users can create or connect OpenSearch Serverless collections directly from the Vercel console. - OpenSearch Agent Skills bring search-specific knowledge, best practices, and multi-step workflows into agents using Claude Code, Cursor, and Kiro. - Kiro’s OpenSearch Launchpad provides guided architecture planning for building search applications. ## Availability - The next generation is generally available in all AWS commercial Regions where OpenSearch Serverless is currently offered. - AWS recommends consulting the OpenSearch Serverless documentation and pricing information for configuration and cost details. The release is intended to let developers deploy production-ready search and vector backends quickly, while avoiding the infrastructure management and peak-capacity costs associated with provisioned OpenSearch clusters.

Announcing Amazon Aurora PostgreSQL serverless database creation in seconds | Amazon Web Services

Amazon’s new Aurora PostgreSQL express configuration lets developers create a serverless database in seconds with two console clicks or a single CLI/API call. It uses preconfigured defaults, IAM authentication, and an internet access gateway to simplify secure connections without requiring a VPC, VPN, or Direct Connect. The feature is designed to accelerate prototyping and application development while preserving Aurora capabilities such as read replicas and automated failover. ## Express Configuration for Aurora PostgreSQL - Creates an Aurora PostgreSQL serverless cluster and instance within seconds. - Uses preconfigured defaults to reduce setup complexity. - Allows customization of: - Cluster identifier - Serverless capacity range during creation - Read replicas and parameter groups after creation - Express-configured clusters do not require an Amazon VPC. - An internet access gateway is enabled by default for secure connections from development tools worldwide. - The gateway is distributed across multiple Availability Zones for high availability. - IAM authentication is configured for the administrator, enabling passwordless database authentication. ## Creating a Database - In the Aurora and RDS console: - Open the Dashboard. - Choose **Create** with the rocket icon. - Review or adjust the express configuration. - Choose **Create database**. - The AWS CLI and SDKs support the `--with-express-configuration` parameter. - A single `create-db-cluster` call creates both the cluster and its instance: ```bash aws rds create-db-cluster \ --db-cluster-identifier channy-express-db \ --engine aurora-postgresql \ --with-express-configuration ``` - The database becomes ready when its status changes to **Available**. ## Connecting to the Database The **Connectivity & security** tab provides several connection methods: - **Code snippets** - Generates connection examples for .NET, Go, JDBC, Node.js, PHP, PostgreSQL, Python, and TypeScript. - Python examples use `boto3` to generate an IAM authentication token and `psycopg2` to connect over SSL. - **AWS CloudShell** - Launches a shell with a preconfigured `psql` connection command. - Developers can immediately run SQL commands at the PostgreSQL prompt. - **Endpoints** - Supports tools such as pgAdmin that use username-and-password fields. - The password is an IAM authentication token valid for 15 minutes. - A new token must be generated if the connection ends or the token expires. ## Application Development Integrations - Aurora is now included among eligible AWS Free Tier database services. - AWS’s enhanced Free Tier offers up to $200 in credits: - $100 upon signup - Up to another $100 through usage of services such as RDS, Lambda, and Bedrock - Integrations with Vercel and v0 allow developers to create or connect to AWS databases quickly. - v0 can use natural-language prompts to generate full-stack applications backed by Aurora PostgreSQL, Aurora DSQL, or DynamoDB. - Existing Aurora databases created with express configuration can also be connected to Vercel. The express configuration is best suited for quickly starting development, experimentation, and prototypes. Developers can begin with minimal networking and authentication setup, then add capacity, replicas, and other Aurora features as their application grows.
