AWS Lambda durable functions now let you encrypt execution data with your own AWS KMS keys instead of relying on AWS-owned ones. Perfect for regulated industries like finance and healthcare where data governance demands customer-controlled encryption. You'll get full control over key rotation and access to execution history, while keeping this separate from function-level encryption. No extra Lambda charges—just standard KMS pricing applies.

AWS just dropped listener rules for Network Load Balancer, and it's a game-changer for dual-stack setups. Now you can route IPv6 traffic to IPv6 targets and IPv4 to IPv4 targets from a single NLB without losing the original client IP—no protocol translation shenanigans needed. Say goodbye to running two separate load balancers or DNS juggling; listener rules handle Layer 3 conditional routing like a boss. Available now across all AWS regions at no extra cost.

Amazon SageMaker AI inference now supports G7 instances powered by NVIDIA RTX PRO 4500 Blackwell GPUs, delivering up to 4.6x faster performance than previous G6 models. These beasts pack 32 GB of GPU memory per GPU, 7x better networking, and massive NVMe storage—perfect for running those chunky 7B–30B parameter models without breaking a sweat. No more painful over-provisioning or model quantizing just to fit in memory. Deploy via SageMaker console, API, or SDK and start serving generative AI models like a pro.
