There are People Behind Serverless 👥

In our previous issue, JavaScript got another new runtime, CodePipeline finally added support for branch-based development, and we learned what to expect from serverless. This week, Cloudflare slays a troll, we dive deeper into LLRT, and compare Lambda containers versus zip packaging. Plus, we have a lot of awesome serverless content from the community!

Serverless News & Announcements 📣

It was a relatively quiet week, but there were still some noteworthy announcements from AWS. This may seem small, but Amazon Data Firehose enabled selecting a time zone for bucket prefixes when delivering streams to Amazon S3. This gives you that tiny extra bit of control that can save you a lot of extra processing on the backend.

Also, API Gateway now supports TLS 1.3, which should have happened a long time ago.

Finally, there's still plenty of buzz around LLRT. Steef-Jan Wiggers shares his round up of reactions.

AWS Lambda Request Timeline
David Behroozi helps clarify what Lambda is actually doing on every request, how that shows in the logs, how to measure latency, and what you can optimize.

Serverless Tutorials 👷‍♀️

There are so many excellent serverless tutorials published every week. Here are some of my favorites:

Serverless Reads 🤓

Cloudflare defeats patent troll Sable at trial
Not about serverless, but important work is being done by Cloudflare and their Project Jengo. Stifling innovation was never the intent of patents.

AWS Lambda Runtime Debate
Omid Eidivandi shares some interesting insight into this debate. Interestingly, the new LLRT runs at about the same cost because it's currently a custom runtime. 🤔

People Matter more than Technology when Building Serverless Applications
I really enjoy Benjamen Pyle's technical writing, but his posts on being a manager and looking past the tech to focus on the humanity behind it, especially resonate with me. And yes, I do like Perl. 😀

The Wrong Way to Use DORA Metrics
Great post by Nočnica Mellifera that reiterates why you might be optimizing DORA metrics for all the wrong reasons.

12 Places Microservice Architecture Doesn’t Work
As much as I like microservices, I also appreciate when people justifiably rail against them. They are not a silver bullet, and often introduce unnecessary complexity.

New from AWS 🆕

Not much from AWS serverless this week, but here are a few announcements that caught my eye:

Star of the Week ⭐️

This week's star is Miguel Ramirez (@MiguelAramis). Miguel, aka The Saas Enthusiast, keeps himself busy blogging on Medium writing lots of articles about serverless that you’ve probably seen featured here in Off-by-none lately. If you’re interested in learning more about cloud technologies, serverless architectures, or business strategy, you’ll want to follow along, too. Thank you, Miguel, for your ongoing contributions, posts, and insights!

Final Thoughts 🤔

I really love combing through all this amazing serverless content every week. It always amazes me to see the different ways people apply it to solve business problems.

As an aside, I've been working on a new open source package called Fraglates that lets you dynamically render compiled Nunjucks templates in microseconds to build SSR websites. It works great with serverless backends, and with template fragment support (aka partials), it's a powerful companion to frameworks like HTMX. I'm currently adding support for Suspense-like streaming, and it's blowing my mind! 😀

Anyway, I'd love some feedback if you get a chance to check it out.

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.
