AWS Elemental MediaTailor now provides automatic secure server-to-server integration with Google's ad platforms

5 May 2026 @ 9:44 pm

AWS Elemental MediaTailor now automatically authenticates server-to-server connections with Google Ad Manager (GAM), Google Campaign Manager (GCM), and Google Display & Video 360 (DV360). This delivers a seamless integration experience for customers using Google's ad platforms. MediaTailor provides server-side ad insertion (SSAI) to personalize ads in video streams. Google requires SSAI providers to establish a secure, authenticated connection when making ad requests and firing ad tracking events. Previously, MediaTailor customers needed to request activation of this integration through an AWS support case and be added to an allow list. With this update, MediaTailor automatically detects requests destined for Google's ad servers and establishes the required secure connection — no customer action required. Specifically: Google Ad Manager (GAM): Server-side ad requests to Google's ad server for publishers are automatically secured, which is r

AWS SAM CLI adds BuildKit support for AWS Lambda functions packaged as container images

5 May 2026 @ 6:50 pm

AWS Serverless Application Model Command Line Interface (SAM CLI) now supports BuildKit for building container images from Dockerfiles, enabling faster, more efficient container image builds for Lambda functions packaged as container images. SAM CLI is a command-line tool for building, testing, debugging, and packaging serverless applications locally before deploying to AWS Cloud. Developers packaging Lambda functions as container images often need advanced build features provided by BuildKit to optimize their images for production. However, SAM CLI previously did not support BuildKit features. Now, with BuildKit support in SAM CLI, you can utilize multi-stage builds to create smaller final images without development dependencies, improved caching to reduce rebuild times, and better parallelization of build steps. BuildKit also enables cross-archite

AWS SAM now supports WebSocket APIs for Amazon API Gateway

5 May 2026 @ 6:31 pm

AWS Serverless Application Model (AWS SAM) now supports WebSocket APIs for Amazon API Gateway, enabling you to define complete WebSocket APIs with minimal configuration in your SAM template. AWS SAM is a collection of open-source tools that make it easy for you to build and manage serverless applications. WebSocket APIs are critical for real-time applications such as chat, live dashboards, AI/LLM streaming, and IoT. However, SAM previously did not support WebSocket APIs, requiring you to manually configure all of the underlying resources in AWS CloudFormation. This made it difficult to debug common issues such as missing IAM permissions for Lambda functions. Now, SAM handles all of this automatically, generating the required resources and permissions from your template. The new resource provides feature parity with

Amazon ElastiCache adds thirteen new Amazon CloudWatch metrics for network capacity planning and engine diagnostics

5 May 2026 @ 6:00 pm

Amazon ElastiCache customers can now detect network throttling, memory fragmentation, and connection exhaustion, using thirteen new Amazon CloudWatch metrics for node-based clusters. You can monitor these host-level and engine-level diagnostics directly from CloudWatch without running INFO commands on individual nodes or calculating baselines from raw byte counters. Network capacity: NetworkBaselineUsageInPercentage, NetworkBaselineUsageOutPercentage, NetworkBaselineMaxUsageInPercentage, and NetworkBaselineMaxUsageOutPercentage report network utilization relative to instance baseline, enabling portable alarms that remain valid across instance type changes. Values above 100 percent signal that a host is consuming burst credits, a leading indicator that a sustained workload will eventually lead to credit exhaustion and throttling. The variants capturing max report pe

Amazon WorkSpaces now lets AI agents operate desktop applications (Preview)

5 May 2026 @ 5:25 pm

Amazon WorkSpaces, AWS's fully managed cloud desktop service, now enables AI agents to securely access and operate desktop applications through managed WorkSpaces environments. Many enterprises run critical business processes on desktop applications—mainframes, ERP systems, and proprietary tools—that lack modern APIs, creating a "last-mile challenge" for AI agents. WorkSpaces now allows organizations to automate everyday workflows at scale while maintaining full enterprise-grade governance and compliance. AI agents built on any framework and running anywhere—cloud-hosted, on-premises, or hybrid—can now connect to business applications with minimal code using industry-standard Model Context Protocol (MCP) integration. Builders gain fast time-to-value without standing up new infrastructure, while IT administrators maintain centralized permissions, logging, and auditing controls identical to human WorkSpaces environments. Enterprise observability features including scre

AWS IoT Core for Device Location adds Confidence Level Configuration and Measurement Type support

5 May 2026 @ 4:59 pm

AWS IoT Core for Device Location now supports two enhancements that give developers greater control over location resolution and richer metadata for resolved device locations. Customers using the Cell ID, Wi-Fi, or Cell+Wi-Fi solvers can now specify a desired confidence level between 50% and 99% when resolving device locations. The confidence level represents the statistical probability that the actual device location falls within the reported accuracy radius. A higher confidence level (for example, 95%) increases certainty that the device falls within the reported radius but produces a larger accuracy radius. A lower confidence level (for example, 50%) yields a smaller radius with less certainty. Customers can now configure this value to balance accuracy and confidence based on their specific requirements. This feature is currently supported for HTTP-based location resolution. This update also introduces a measurement type field in resolved location metadata, givi

Amazon MQ now supports in-place major version upgrades for RabbitMQ 4

5 May 2026 @ 4:50 pm

Amazon MQ now supports in-place version upgrades for RabbitMQ brokers, enabling you to upgrade your brokers to RabbitMQ 4 without creating a new broker or migrating your data. You can now upgrade from RabbitMQ 3.13 to 4.2, directly from the Amazon MQ console, AWS CLI, or API. In-place upgrades preserve your broker configuration, queues, exchanges, bindings, users, and policies. RabbitMQ 4.2 introduces breaking changes including the removal of classic mirrored queues and migration from Mnesia to the Khepri metadata store. Brokers must be running on M7G (Graviton) instance types and must not have classic mirrored queues to be eligible for the upgrade. A queue migration tool is available to convert classic mirrored queues to quorum queues before upgrading. During a major version upgrade, your broker will be unavailable while Amazon MQ performs the upgrade. To upgrade your broker, simply select RabbitMQ 4.2 as your version through the AWS Management console, AWS CLI, o

Amazon Quick now integrates with New Relic for observability-driven AI agents

5 May 2026 @ 4:35 pm

Amazon Quick, your AI assistant for work, now integrates with New Relic's AI agents, enabling on-call engineers, SREs, and engineering leaders to investigate incidents, generate root cause analysis briefs, and create tracked tasks without leaving their Amazon Quick workspace. After connecting to New Relic's remote model context protocol (MCP) server, you can invoke New Relic's AI agents directly from a conversational prompt in Quick – including alert insights, user impact analysis, log analysis, transaction diagnostics, and natural language NRQL queries. In a single chat exchange, you can investigate an incident across your observability data, generate a root cause analysis (RCA) document with evidence links, and send it as an email attachment. Quick Flows can also invoke New Relic AI agents to automate recurring triage runbooks or escalation workflows. Because Quick surfaces responses alongside enterprise knowledge stored in Spaces&

EC2 Instance Store CSI driver now generally available in EKS add-ons

Amazon Elastic Kubernetes Service (Amazon EKS) now supports using the Amazon EKS console, and AWS Command Line Interface (CLI) to install and manage the Amazon Elastic Cloud Compute (EC2) Container Storage Interface (CSI) driver. This launch enables a simple experience for attaching a EC2 local instance store to an EKS cluster. The Amazon EC2 Instance Store CSI driver is a plugin that enables Kubernetes to use EC2 instance store volumes. Instance store volumes provide ephemeral block-level storage that is physically attached to the host computer. The driver manages the lifecycle of these NVMe storage volumes and makes them available as Kubernetes persistent volumes.  This feature is available in all commercial reg

Amazon Connect Cases now supports customer profile identity resolution

5 May 2026 @ 3:25 pm

Amazon Connect Cases now automatically reassociates cases when duplicate customer profiles are merged, so agents always see a complete case history for each customer. When the same customer has multiple profiles, such as when they reach out through different channels or provide different contact details, Identity Resolution in Amazon Connect Customer Profiles detects and merges those duplicates, and Cases now brings all associated cases together under the unified profile. Agents no longer have to search across profiles or piece together a customer's history manually. Amazon Connect Cases is available in the following AWS regions: US East (N. Virginia), US West (Oregon), Canada (Central), Europe (Frankfurt), Europe (London), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), and Africa (Cape Town).

ASP.NET tempDirectory shared for multiple apps?

6 May 2026 @ 8:57 am

If we have multiple ASP.NET Framework 4.7.2 web apps deployed on the same IIS server, can we specify the same TempDirectory? Meaning the attribute TempDirectory of the web.config compilation section under system.web. It looks like the system puts the actual files in some structure of sub folders, so it looks like there will be separation. But I'm not sure... In case it matters, several of our web apps are the same code base, but with different configurations per site and virtual folder.

When will DSClosestFlag of the DC Locator be set to 1?

6 May 2026 @ 8:55 am

Imagine an environment with two sites, HQ and Branch. Both sites have a domain controller. A client from Branch wants to locate the optimal domain controller, and it so happens that the first query is performed against a domain controller from HQ. The most optimal domain controller should be the one from the Branch site. However HQ is the closest site to Branch. Will DSClosestFlag then be 1? Or does the domain controller know that there is a dedicated domain controller in Branch and therefore set it to 0? If the flag is 1, this would lead to selection of a non-optimal domain controller? I have already checked the official Microsoft documentation, but with the wording it is not exactly clear to me, when the domain controller thinks it is closest or not.

Remove Child Domain From Syncing

5 May 2026 @ 7:28 pm

I have a Parent/Child domain setup in a test environment. The parent domain contains 3 DCs with DC01 holding the FSMO roles. The Child domain also has 3 DCs with DC01 holding the PDC role for the Child domain. We doing some testing where we want to disconnect the child domain for about a month or 2 to do some stand alone testing. In Active Directory Sites & Services we have 2 Sites setup. Site 1 (Parent Domain): P-DC01, P-DC02, P-DC03, C-DC03 Site 2 (Child Domain): C-DC01, C-DC02 The reason for this topology is so that the Child domain (DC03) information remains synced with the Parent domain while the Child Domain is disconnected and incase of Domain Failure while it is disconnected from testing. While the Child Domain is disconnected we want to make sure users can login without an issue. When the Child Domain is connected we have created an Site Link so the Parent Domain Site sync with the Child Domain site. There are no DC entries in

High network traffic causes SSH to hang

5 May 2026 @ 2:30 pm

I'm connecting to a mobile computer (SBC) using wifi. This computer is transmitting data continuously, in the form of small and frequent UDP packets. I receive the data fine on my PC, but while the data is being transmitted, my SSH connection hangs. When the data stops, SSH comes back. There should be enough bandwidth, iperf shows 125Mbps and the data takes only 20 to 40 Mbps. Are there any reasons that of many small UDP packets might make this happen, other than consuming the bandwidth? Could this create some relevant overhead that causes this? How could this completely hang SSH, not just make it slow? Can I tune the SSH somehow, or make the data stream somehow to ensure I have SSH always somewhat responsive? EDIT: Here is some more information. I'm transmitting 2600 packets per second. There's no data loss in the UDP stream. The two machines are connected directly to each other, the SBC is operating in AP mod

Mailman3: How to configure the ARC section on a Debian system with postfix and opendkim

My server has mailing lists for about a hundred domains. Mailman3 works currently: I can send from a mailing list and the emails reach their destination. The source email are properly DKIM-signed. The issue is that since Mailman3 modifies the emails in transit, this DKIM fails when it reaches its destination. I tried to define the /etc/mailman3/mailman.cfg [ARC] section but I don't understand what to put in each field. Does Mailman3 requires its own DKIM key-pair? Or does it uses one of OpenDKIM key-pair?
