Surprise DuckDB Acquisition! AWS Welcomes DuckLabs and Rolls Out Agentic Resource Discovery

Hi everyone, it's me! I've got a ton of exciting AWS news to share with you today. The one that surprised me the most this week was the news that AWS is acquiring the company behind DuckDB! Let's dive in.

What was announced?

In this week's AWS Weekly Roundup on the AWS Blog, the biggest story was the acquisition of DuckLabs. DuckLabs is based in Amsterdam and builds DuckDB, the popular open source analytical database. DuckDB runs in-process and executes SQL directly against files like Parquet, CSV, and JSON, and it's best suited for everyday analytical queries under about 1 terabyte.

The other big headline is Agentic Resource Discovery (ARD), a new open specification released under the Apache 2.0 license. It's designed to give a unified way to describe and discover resources like agents, tools, and MCP servers.

Why it matters

DuckDB has been gaining popularity among data engineers for being lightweight and fast enough to run comfortably on a laptop. AWS acquiring the company behind it feels like a signal that a major cloud provider is putting real weight behind lightweight, high-speed analytical engines.

ARD matters too. Right now, agents, tools, and MCP servers are scattered across different clouds, on-premises environments, and SaaS platforms, and finding and connecting them individually has been a hassle. ARD aims to work like DNS: publishers describe a resource once, and consumers can discover it from anywhere. As agent-to-agent collaboration keeps growing, having a shared discovery mechanism like this feels timely.

What changes

On the DuckLabs acquisition, AWS made clear that DuckDB will stay open source, continuing to be governed under an independent foundation under the MIT license, with co-founders Hannes Mühleisen and Mark Raasveldt still leading its technical direction. AWS plans to integrate DuckDB's speed with enterprise-scale services like Amazon S3, Amazon Redshift, and Amazon Athena. In other words, the DuckDB you might already be running locally or standalone could soon connect much more smoothly with AWS's data services.

ARD is still just a freshly published specification, so how it plays out depends on which services and tools adopt it. But for engineers building with agents, it could mean a lot less friction around finding and registering the tools and agents you want to use.

Dive Deep

There were plenty of other practical updates in this week's roundup too.

• Amazon ECS: now automatically detects and recovers from lost agent connectivity. Fargate and managed instances recover automatically, and EC2 can be integrated with custom recovery workflows. No extra cost.
• AWS Lambda: Node.js 26 and Python 3.15 runtimes are now available in public preview. They're not recommended for production yet, but they're useful for checking your code's compatibility ahead of general availability.
• AWS IoT Core: added a native InfluxDB rule action, letting you route time-series data straight to InfluxDB without writing custom code.
• Amazon GameLift: Server SDK 5 now includes automatic protection against layer 3/4 DDoS attacks like UDP reflection and SYN floods, at no extra cost.
• Amazon SageMaker HyperPod: expanded support for Ray workloads, manageable from Amazon SageMaker Studio, with automatic recovery and Grafana dashboard integration.
• Amazon EC2: just turned 20 years old, now offering more than 1,200 instance types across 39 regions, with custom silicon that has evolved to the Graviton5 and Trainium3 generations.

Wrap-up

• AWS is acquiring DuckLabs, the company behind DuckDB. DuckDB stays open source, governed by an independent foundation under the MIT license
• A new open specification, Agentic Resource Discovery (ARD), aims to make agents and MCP servers discoverable the way DNS makes hosts discoverable
• Plenty of practical updates too: ECS agent connectivity auto-recovery, new Lambda preview runtimes, IoT Core's InfluxDB integration, GameLift's DDoS protection, and expanded Ray support on SageMaker HyperPod
• EC2 just hit its 20th anniversary, now spanning more than 1,200 instance types, a number that says a lot about how far it's come

If you work anywhere near data platforms or agent orchestration, this week's news is worth a closer look.
