Amazon Bedrock Means Business 🪨

In our previous issue, Neon and Supabase both went GA, Amazon Bedrock launched in Sydney, and CloudFront added (slightly) better support for Lambda fUrls. This week, Amazon Bedrock continues to rollout some impressive updates, Powertools gets a parser, and Vercel rolls back Edge rendering. Plus, we have lots of serverless content from the community!

🧑‍🏫 Don't forget to take last week's Off-by-none Cloud Quiz! 7 questions to test your knowledge of recent cloud news and learn something along the way. Plus it's fun! 😉

Serverless News & Announcements 📣

AWS made a lot of announcements about AI this past week, so let's get those out of the way.

Anthropic's Claude 3 Opus model and two Meta Llama 3 models are now available on AWS Bedrock. These are quite powerful, so if you're interested, I suggest reading the Claude 3 Opus model official post and the Meta Llama 3 models official post for more details. They also announced that Amazon Titan Image Generator and watermark detection API are now available in Bedrock. The Titan Image Generator is rather impressive, especially its instant image customization capability.

Also, Amazon Bedrock model evaluation is now generally available, letting you test different models to determine which ones are best suited for your use case. And Guardrails for Amazon Bedrock is now available with new safety filters and privacy controls. Parts of this get pricey, but a few things are included that can certainly make working with these models a lot safer. Finally, you can now import custom models in Amazon Bedrock (preview).

Two non-GenAI related AWS announcements were that AWS CloudFormation ChangeSets now offer enhanced change visibility for deployments and Amazon Athena announced federated query pass-through.

The latest version of Powertools for AWS Lambda (TypeScript) was released and adds a very cool "Parser" feature that uses Zod to validate data.

And not to be left out, Meta Llama 3 is now available on Cloudflare Workers AI as well.

Finally, according to Guillermo Rauch from Vercel, "We've run the experiment. Edge rendering doesn't work: it's slower, has worse DX & runtime limits. We reverted it." Edge has been over-hyped from the beginning (though it still has its place), but there's nothing wrong with running experiments to see where efficiencies can be gained. Edge rendering might work in niche scenarios, but round trips x distance it the most important calculation.

Final Thoughts 🤔

I know, I know, lots of GenAI has been creeping into the newsletter. I think much of it is over-hyped (like Devin), but there are also some really interesting use cases for it out there (and no, I'm not talking about chat bots 😉). I personally find it fascinating once you wade through some of the sensationalism. Anyway, let me know what you think.

Until next time,

I hope you enjoyed this newsletter. We’re always looking for ideas and feedback to make it better and more inclusive, so please feel free to reach out to me via X, LinkedIn, or email.
