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.

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/introduci… 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. 🧵

🚀 This is HUGE! Game-changing launch for AWS Lambda logging… makes observability significantly cheaper and easier for serverless applications 1️⃣ volume-based tiered pricing for Lambda logs in CloudWatch 2️⃣ New logging destinations for Lambda - Amazon S3 and Firehose) 🧵1/n

Here's a Friday fun moment: #AWSStepFunctions just released support for JSON Lines (JSONL) as a format for Distributed maps. Take a read -> aws.amazon.com/blogs/compute/…

The theme of both my #AWSreInvent2024 talks this year has been "right tool for the right job" 🛠️ @maschnetwork and my talk on choosing containers or serverless functions takes you through: 1/ The differences between containers and serverless functions... youtube.com/watch?v=OUXZEg…

🔍 Live at #reInvent Expo! 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 #AWS #Lambda #Serverless #reinvent2024

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.

These can be handy 👉 New Amazon Q Developer agent capabilities include generating documentation, code reviews, and unit tests aws.amazon.com/blogs/aws/new-… #AWS #reInvent #DevEx #DevOps

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!

@goranopacic Storing snapshots has costs. SnapStart for Java does not charge for that, but has to clear the idle cache after sometime. SnapStart for Python and .NET gives the control back to the developers. You can keep the idle cache as long as needed

same story we had with Java. SnapStart won’t make a difference for cold start just like that. it only makes sense if you pack some precomputed data with it or you have to initialize substantial number of libraries. pricing is just another example of Lambda getting too complicated

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. aws.amazon.com/blogs/aws/aws-…

🚀🎂🔟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/2024/11/aws-la…

🚀 AWS Lambda is leveling up your local coding experience with some new VS Code features 💻 aws.amazon.com/blogs/compute/… #Serverless

Unleash the power of speed, safety, and sustainability with serverless & Rust! 🏆 James Estham shares his insights on this winning combination at #RustLab2024. Don't miss this talk on building modern business apps 🚀 👉rustlab.it/speakers/easth… @plantpowerjames

@DRo_604 @phil_jong If Beanstalk supports ECS Fargate, that would be so nice.

We're moving Amazon Elastic Beanstalk forward! Windows platform updates, Amazon Linux 2023 support, more instance types. We're working hard to keep Beanstalk the best place to host full stack web apps! Reach out to @phil_jong with any asks. docs.aws.amazon.com/elasticbeansta……

Here’s another goody. We now help new (and old) customers get started with VS code in the console. aws.amazon.com/blogs/compute/…

@QuinnyPig People use response streaming and API Key auth a lot for GenAI projects. WAF protection, public/private endpoints, and custom domains are also frequent asks from the customers. To meet these requirements, customers usually need to build a proxy layer. This tool makes it simpler.

@sunhua What makes this ideal for GenAI projects?

🔥 New tool alert for #AWS developers! Unleash the power of Lambda with the new serverless web gateway: ✅ Response streaming ✅ API Key authentication ✅ Public & private endpoints ✅ Custom domains ✅ WAF protection Ideal for #GenAI projects. Deploy on App Runner or Fargate. Explore now: github.com/aws-samples/aw…

@Hesketh_GD Yes. It’s like a self hosted Lambda function URL, supports response streaming, can be deployed to VPCs with custom domain names.

@sunhua When would you use this over API Gateway? Because API Gateway does not support streaming?
