Amazon CloudWatch now allows customers to automatically enable Amazon Elastic Compute Cloud (EC2) detailed monitoring across their AWS Organization. Customers can create enablement rules in CloudWatch Ingestion that automatically enable detailed monitoring for both existing and newly launched EC2 instances matching the rule scope, ensuring consistent metrics collection at 1-minute intervals across their EC2 instances. EC2 detailed monitoring enablement rules can be scoped to the whole organization, specific accounts, or specific resources based on resource tags to standardize the configuration across EC2 instances. For example, the central DevOps team can create an enablement rule to automatically turn on detailed monitoring for EC2 instances with specific tags, e.g., env:production, and ensure Auto Scaling policies respond quickly to changes in instance utilization. CloudWatch's auto-enablement capability is available in all AWS commercial regions. Detailed monitoring metrics wi...

Amazon Bedrock AgentCore Runtime now supports the Agent-User Interaction (AG-UI) protocol, enabling developers to deploy AG-UI servers that deliver responsive, real-time agent experiences to user-facing applications. With AG-UI support, AgentCore Runtime handles authentication, session isolation, and scaling for AG-UI workloads, allowing developers to focus on building interactive frontends for their agents. AG-UI is an open, event-based protocol that standardizes how AI agents communicate with user interfaces. It complements the existing Model Context Protocol (MCP) and Agent-to-Agent (A2A) protocol support in AgentCore Runtime. Where MCP provides agents with tools and A2A enables agent-to-agent communication, AG-UI brings agents into user-facing applications. Key capabilities include streaming text chunks, reasoning steps, and tool results to frontends as they happen; real-time state synchronization that can update UI elements such as progress bars and dashboards; structured tool ca...

The FOSSASIA Summit 2026 was an incredible gathering of developers, open-source contributors, startups, and technology enthusiasts from across the region. This year, Azure Cosmos DB and Azure DocumentDB were present at the summit with both technical sessions and a dedicated booth, giving us a great opportunity to connect with the community and talk about building modern applications with cloud-native databases. A Personal Note This was my third time attending FOSSASIA, and it was special in many ways. It was also my first time attending the summit in Bangkok, Thailand, and the venue and overall experience were fantastic. Over the years, I’ve been able to see how both my own journey and the conference itself have evolved. Each year the summit continues to grow, bringing together more developers, communities, and organizations that are passionate about open source and emerging technologies. One of the highlights for me was seeing the strong presence from the open-source ecosystem. It w...

We continue our historical survey of Windows stack-checking functions by looking at the PowerPC. The weird thing here is that on PowerPC, you ask for the negative of the stack frame size. We'll see why soon. ; on entry, r12 is the *negative* of the number of bytes to allocate ; on exit, stack has been validated (but not adjusted) chkstk: subi r0, r12, PAGE_SIZE - 1 ; expand by another page to make sure we get it all ; get the stack limit for the current stack cmpwi sp, 0 ; check what kind of stack we are on¹ add r0, r0, sp ; r0 = proposed new stack limit bge+ usermode ; nonnegative means user mode mfsprg r11, 1 ; get kernel thread state lwz r11, StackStart(r11) ; where the stack started subi r11, r11, KERNEL_STACK_SIZE ; where the stack ends b havelimit usermode: lwz r11, StackLimit(r13) ; get stack limit from TEB havelimit: sub r0, r11, r0 ; r0 = bytes of stack ...

We’re excited to announce the general availability of private network support for Azure Cosmos DB mirroring in Microsoft Fabric , enabling customers to replicate operational data into Fabric from Azure Cosmos DB accounts secured with private endpoints or virtual networks while continuing to operate within their existing network security models. As more organizations connect operational data with analytics and AI to power new insights and intelligent applications, the ability to do so securely has become increasingly important—making private network support a key capability for bringing operational data into Fabric without compromising established security boundaries. Bringing secured operational data into Fabric Azure Cosmos DB mirroring makes it easy to continuously replicate operational data into Microsoft Fabric, where it can be used across analytics and AI experiences without building and maintaining custom ingestion pipelines. With private network support now generally availabl...

Starting today, Amazon EC2 Hpc8a instances are available in Asia Pacific (Tokyo) and AWS GovCloud (US-West) regions. These instances are powered by 5th Gen AMD EPYC processors (formerly code named Turin). With a maximum frequency of 4.5GHz, Hpc8a instances deliver up to 40% higher performance and up to 25% better price performance compared to Hpc7a instances, helping customers accelerate compute-intensive workloads while optimizing costs. Compared to Hpc7a instances, Hpc8a instances also provide up to 42% higher memory bandwidth, further improving performance for memory-intensive simulations and scientific computing workloads. Built on the latest sixth-generation AWS Nitro Cards , Hpc8a instances are designed for compute-intensive, latency-sensitive HPC workloads. They are ideal for tightly coupled applications such as computational fluid dynamics (CFD), weather forecasting, explicit finite element analysis (FEA), and multiphysics simulations that require fast inter-node communicatio...
