Hi, welcome to another weekly update.

Real-World Serverless podcast

Inspired by what Jeremy Daly has been doing on ServerlessChats, I decided to take the plunge and start my own podcast too. I want to play to my strength as an independent consultant, and focus on the success and struggles of individual companies and share their serverless stories from the trenches.

So I’m excited to launch the Real-World Serverless podcast. The first episode is already out and has been played over 500 times in the first 3 days, so huge thanks to everyone who have shown an interest in the podcast. In this first episode, I spoke with Ricardo Espirito Santo to talk about Zoopla and how they’re using serverless, their experience with it so far and the challenges they have experienced with serverless technologies.

If this sounds like something you’re interested in, then go to realworldserverless.com and listen to the full episode, and follow us on Twitter @RealWorldSls for updates. We have some cracking episodes coming your way in the next few weeks including discussions with Joe Emison around monorepoes and a conversation about vendor lock-in with Moneyou, a Dutch bank based here in Amsterdam.

New posts

I wrote a two-part article for AWS Open Source blog on “24 open source tools for the serverless developer”:

  • part 1 covers deployment frameworks, Serverless plugins and CLI tools
  • part 2 covers libraries and SAR apps

Over on the Lumigo blog, I also published a new post on the 5 reasons you should use EventBridge instead of SNS in your project. TL;DR – lots more targets, support for third-party partner events, content-based filtering, automated schema discovery and input transformation.


I gave a talk at the Frontend Developer Love conference in Amsterdam and talked about why Serverless gives frontend developers superpowers!

I gave the opening keynote at the first ever ServerlessDays Rome conference and talked about how we can use Serverless technologies to empower modern businesses and allow them to focus on their differentiating factors.

I ran a free webinar with CodeMotion on the common mistakes companies made when they first adopt serverless.

The session was recorded and available here:


It’s the last chance to sign up to my Production-Ready Serverless workshops next week in London and Amsterdam. If you’re interested in joining us, here are the sign-up links:

If you can’t make these dates, then don’t worry, you can still catch me later in the year:

AWS announcement

I don’t share these anymore as many others (such as the @awswhatsnew Twitter account) do a much better job of aggregating them than me. But I want to share an update that many of you would be very excited about. CloudFront has massively improved the deployment time for CloudFront distributions (including Lambda@Edge)!

Thank you to my patrons

Finally, I want to give a shout out to my patrons:

Alexis, Andre Silva, Boseok In, Dome Jantaphat, Dragan Cabarkapa, Ebru Cucen, Efi Merdler-Kravitz, Hrafnkell Palsson, Jon Barber, Jonathan Kosgei, Ken Ng, Kevin Woods, Luis Gutierrez, Mark David McCreary, Marko @ Serverless Life, Michael Wills, Shawn MacIntyre, Tendies123, Will Saunders, Yinan Xue

Hi, I’m Yan. I’m an AWS Serverless Hero and I help companies go faster for less by adopting serverless technologies successfully.

Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.

Hire me.

Skill up your serverless game with this hands-on workshop.

My 4-week Production-Ready Serverless online workshop is back!

This course takes you through building a production-ready serverless web application from testing, deployment, security, all the way through to observability. The motivation for this course is to give you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands.

We will start at the basics and give you a firm introduction to Lambda and all the relevant concepts and service features (including the latest announcements in 2020). And then gradually ramping up and cover a wide array of topics such as API security, testing strategies, CI/CD, secret management, and operational best practices for monitoring and troubleshooting.

If you enrol now you can also get 15% OFF with the promo code “yanprs15”.
