I built Lambda Web Adapter as an AWS SA so web apps could run on Lambda unchanged.
Now Lambda Web Functions makes it native: HTTP straight to your code. 🎉 Congrats to the team!

Check out Kiro!
Kiro moves the AI IDE from 'vibe coding' to development driven by specifications.
Specs allow AI-powered development that's repeatable, scalable, and deals better with large and complex projects.
This is Kiro - the AI IDE that actually works on your messy, real-world projects. Other AI tools lose context when projects get complex. Kiro gives you spec-driven development that scales beyond prototypes.
Free preview available now spr.ly/6016429H8

Introducing Kiro, an all-new agentic IDE that has a chance to transform how developers build software.
Let me highlight three key innovations that make Kiro special:
1 - Kiro introduces spec-driven development, helping developers express their intent clearly through natural language specifications and architecture diagrams for complex features. This comprehensive context helps Kiro’s AI agents deliver better results with fewer iterations.
2 - Kiro features intelligent agent hooks that automatically handle critical but time-consuming tasks like generating documentation, writing tests, and optimizing performance. These hooks work in the background, triggered by events like saving files or making commits. It’s like having an experienced developer constantly reviewing your work and handling the maintenance tasks that often get delayed.
3 - Kiro provides a purpose-built interface that adapts to how developers work. Whether you prefer chat interactions or working with specifications, Kiro supports your workflow while keeping you in control of the development process.
Kiro is really good at "vibe coding" but goes well beyond that. While other AI coding assistants might help you prototype quickly, Kiro helps you take those prototypes all the way to production by following a mature, structured development process out of the box. This means developers can spend less time on boilerplate code and more time where it matters most – innovating and building solutions that customers will love.
Starting today, Kiro is available for free during preview and supports most popular programming languages.
Here’s how to get started with @kirodotdev today: kiro.dev/blog/introducing-ki…
Excited to see how developers use Kiro, and to work with the developer community to continue to shape Kiro moving forward.

In honor of yesterday's Aurora DSQL GA, I wanted to talk about some of the lessons from nearly 20 years of operating AWS we've built into DSQL, and how they help you build more reliable applications. 🧵

Stop by Modern Applications & Open Source Zone to see how Lambda Debugging Kit lets you debug cloud-running Lambda functions from your local IDE. No more blind debugging!
⏰ Demo: 4PM - 5PM

Lambda SnapStart for Python reduces cold start for large data processing Lambda functions. I made a Serverless DuckDb demo with over 10x cold start improvements. Come and see in the Expo.

This is a MASSIVE feature for EventBridge & Step Functions. Makes it super easy to integrate with Container or EC2 workloads — just setup your private API as a target. Fantastic work on this by the team!

The pre:Invent goodies keep coming! This is a big one! Sub-second function start up times for Python and .NET! We did this for Java functions in 2022 and excited to see more workloads optimized through this launch.

🚀🎂🔟Happy 10th Birthday AWS Lambda!
One of the most impactful cloud services was announced by @jeffbarr and @werner today in 2014!
The event-driven model became the start of #serverless #AWS .

To mark #AWS Lambda's 10th anniversary, I'm sharing the internal PR/FAQ doc that launched it. It's a rare glimpse into the customer challenges we observed at the time and our vision for serverless computing back in the 2010s. Read it here: allthingsdistributed.com/202…
