Web Search on AWS Bedrock now supports domain filtering and user location controls - devamazonaws.blogspot.com

Web Search on AWS Bedrock now supports two new controls that give you more precision over the results that ground a model's response: domain filtering and user location. Both are configured directly on the web_search tool in your existing OpenAI Responses API request. With domain filtering, you can restrict Web Search results to a set of domains you choose. Using the filters parameter, you specify up to 100 allowed_domains to limit results to trusted sources, or up to 100 blocked_domains to exclude sources you don't want. This is useful when you want responses grounded only in specific sites, or when you need to keep certain domains out of results. With user location, you can optionally specify location parameters so that Web Search can return results relevant to that geography. This helps with location-dependent questions, such as regional availability or local services. Domain filtering and user location are available in all AWS Regions where Web Search is supported: US...

AWS Transit Gateway and AWS Cloud WAN now support 1:1 NAT - devamazonaws.blogspot.com

AWS Transit Gateway and AWS Cloud WAN now provide managed one-to-one network address translation (NAT) directly on their attachments, through integration with Regional Private NAT Gateway. This enables customers to connect private networks that share the same IP address ranges without renumbering either network, deploying a NAT appliance, or writing return-traffic rules. Networks with overlapping Classless Inter-Domain Routing (CIDR) blocks have long been unable to communicate, a common blocker during mergers and acquisitions, when connecting partner networks over AWS Site-to-Site VPN, in multicloud connectivity, and when independently provisioned VPCs need to interconnect. Using this capability, customers can define address-translation rules on a AWS Transit Gateway or AWS Cloud WAN attachment, specifying the private IP range each source CIDR translates to, across Amazon VPC, AWS Site-to-Site VPN, AWS Direct Connect, and SD-WAN appliances connected through Transit Gateway Connect. B...

Amazon MSK Connect now supports pausing and resuming connectors - devamazonaws.blogspot.com

Amazon MSK Connect (Amazon Managed Streaming for Apache Kafka Connect) now supports pausing and resuming connectors, letting you temporarily pause a connector from processing records and resume it later. This is useful when you need to stop data flow during maintenance on a source database or a sink target, or to pause processing while you investigate an upstream or downstream issue. Amazon MSK Connect is a fully managed service that allows you to deploy, monitor, and scale Apache Kafka Connect connectors with Amazon MSK (Managed Streaming for Apache Kafka). Previously, pausing a connector meant deleting it and recreating it - a more disruptive operation, adding risk and operational overhead. With this launch, you can pause a running connector and resume it in place when you are ready — a paused connector keeps its configuration, capacity settings, and committed offsets, and its tasks continue processing from the offsets they last committed when you resume. This capability is ava...

[MS] From Local Development to CI Workflows with the Azure Cosmos DB Emulator - devamazonaws.blogspot.com

Image
When you change a database-backed feature, a successful HTTP response isn't enough. You need to know that the write reached storage, the application retrieved the updated record, and the next answer reflects it. The Azure Cosmos DB Emulator runs locally in Docker and lets us use the SDK we'll use in production. We'll develop against it first, then carry our tests into GitHub Actions. Each update to an open pull request must pass against a fresh emulator before we merge. Building on Theo van Kraay's local development walkthrough , we'll use FleetCharge , a Python demo built with Microsoft Agent Framework and FastAPI. Ollama runs Phi-3.5 locally, so model inference stays local too. A depot will change where drivers collect their paperwork. Our test needs to prove the update reached the database and changed the application's answer. An HTTP 200 alone won't tell us either of those things.

AgentCore Gateway now supports Bedrock InvokeModel APIs and model fallback - devamazonaws.blogspot.com

Amazon Bedrock AgentCore Gateway now supports the Amazon Bedrock InvokeModel and InvokeModelWithResponseStream APIs on its inference endpoint, along with model fallback routing for inference traffic. With InvokeModel support, you can point your existing Amazon Bedrock SDK integration at the gateway and reach any model provider through one governed endpoint, without rewriting client code for each provider. With model fallback, the gateway automatically routes a request to an alternative model or provider when the primary destination is throttled, out of capacity, or unreachable, so your agents stay available without each client implementing its own retry logic. For fallback routing, you define an ordered chain of alternative destinations in a gateway rule, along with the conditions that trigger a switch, such as throttling, server errors, or response timeouts. A built-in circuit breaker skips destinations that are currently failing, so requests reach a healthy destination faster and y...

[MS] 🚀 React Native Windows v0.85 is here - devamazonaws.blogspot.com

We're excited to release React Native Windows 0.85.0, built on React Native 0.85.3. React Native Windows v0.85 completes the move to the New Architecture, updates the Windows build toolchain, and adds new component capabilities along with touch, text, accessibility, and rendering fixes. 🔥 What's New in RNW v0.85? New Architecture only The legacy architecture has been removed. Apps still on the old architecture must migrate to Fabric before upgrading to 0.85. New projects already target the New Architecture. 🔗 New vs. Old Architecture · React Native for Windows Updated toolchain React Native Windows 0.85 requires: Visual Studio 2026 .NET 10 Windows App SDK 1.8 ( Microsoft.WindowsAppSDK 1.8.260508005) Update your build environment before upgrading. Modal title bar and border control Modal now supports hideTitleBar and hideBorder , so Windows apps can present dialogs without the default native title bar or border when that fits the design.

AWS Network Firewall now supports Route 53 Resolved IP Validation - devamazonaws.blogspot.com

AWS Network Firewall now supports IP validation, extending domain-based filtering beyond HTTP/HTTPS to protocols such as SFTP and SSH. This new capability validates that a connection's destination IP address was resolved through your VPC's Amazon Route 53 VPC Resolver, closing security gaps where clients could bypass domain rules. This feature enables Network Firewall customers to implement domain filtering rules for any protocol, not just HTTP/HTTPS, providing more flexible security policies than IP-based rules alone. It simplifies protection against Server Name Identifier (SNI) spoofing by validating the IPs resolved by the Route 53 VPC Resolver against the SNI, ensuring traffic only reaches legitimately resolved destinations. Organizations can now enforce consistent domain-based security policies across all outbound traffic types, from web applications to file transfer protocols, without complex workarounds. Additionally, Route 53 Resolver DNS Firewall can be used with you...
