Issue #102: All in on EDA

Serverless Superhero

Our serverless superhero this week is Elad Ben-Israel, co-founder and CEO of Wing and creator of the CDK! Elad has done so much for modern cloud development, he has literally helped shape the way we get resources into production - and he’s doing it again with Wing! Elad is a visionary in this space and a phenomenal speaker. Thank you for everything, Elad!

Interesting Reads

Ran Isenberg released part two of his series on generating OpenAPI documentation from your code, this time focusing on CI/CD workflows and proper guardrails. This is a great, pragmatic approach to documentation generation. I really like the addition of breaking change detection in the workflow, which is the most important part of API-first development in my opinion.

I love seeing novel approaches to solving problems we’ve seen time and time again. Especially when the novel approach is more secure and potentially more environmentally sustainable. This is exactly what Jason Wadsworth did in his post on Lambda-less AppSync for SaaS. He doesn’t describe the approach as more secure or green in the article - those are my words. But it definitely is! He shows us how to connect AppSync to a Step Function workflow with direct integrations to DynamoDB using tenant-specific roles for data access. I love the idea and his inclusion of the trade-offs to this approach.

There’s typically a “one way or the other” mentality when it comes to building serverless APIs: single responsibility functions and lambda-liths. Last week Luca Mezzalira published a great article showing us there’s another way to approach the problem. He explains the pros and cons of both lambda-liths and single responsibility functions, then dives into his alternate approach.


Event-driven architectures are taking 2024 by storm. Yes, they’ve been around for decades, but this year they really seem to be surging in popularity. James Eastham was on the #believeinserverless livestream last week and gave an incredible talk on all things EDA, including the different types of events, why they are beneficial, what the trade-offs are with request/response architectures, and so much more. There was lots of valuable discussion at the end of the talk too, with actionable paths to get started with events.

Tip of the Week

Since EDA is top of mind for us this month, I thought I’d share an important post from David Boyne where he shares his thoughts on governance in event-driven architectures 🔥

New Releases

Big news for Bedrock! Last week both the Mistral FMs and Claude 3 Sonnet are available for use. From what I hear, these are turning up the heat!

In a big announcement, AWS is offering free data transfer out to internet when moving out of AWS. Specifically, they are offering 100GB of data transfer for free automatically and asking users contact AWS Support if you need more than that. Sounds like a good deal to me!

Last Words

Hello, welcome, and congratulations to all the new AWS Community Builders and Heroes! I am so excited for each and every one of you and am thankful for your willingness to share your journeys and experiences with the community. I look forward to hearing more from you and am ready to see what you build!

If you’d like to make a recommendation for the serverless superhero or for an article you found especially useful, send me a message on Twitter, LinkedIn, or email.

Happy Coding!
