Hi, welcome to another weekly update.

Production-Ready Serverless workshop goes virtual!

Starting from May 4th, I will be running a 4-week instructor-led workshop that teaches you everything you need to know to build a production-ready serverless application. It’s based on the same demo app as my Manning course, but all the code has been completely rewritten for Node.js 12.x and the lectures have been updated to reflect changes and new features in AWS in the last 2.5 years.

Over the 4 weeks, you will spend around 4-5 hours per week, and build an e-commerce web app from scratch. We will take you through everything from the basics, to testingdeploymentsecurity and operational best practices for monitoring and troubleshooting.

At the start of each week, we will release new lectures and hands-on exercises for you to do in your own time. You can ask questions and interact with me and other students on our Discord server (which will also be available after the workshop). And then on Friday, we will run two live Q&A sessions to cater for all the timezones. Where we will discuss questions that were asked during the week and answer any live questions from the audience as well.

Enrol now and skill up your Serverless game! And may the force be with you ;-)

Real-World Serverless podcast

Since the last update, we have 4 new episodes for you:

It has been a real pleasure speaking with all these companies from different walks of life and seeing how everyone is using serverless technologies. We have more real-world serverless stories for you in the coming weeks, including those from DVLA and DAZN.

Head over to realworldserverless.com to listen to all the available episodes, and follow us on Twitter for regular updates and snippets.

New posts

I have been working with AppSync for the last couple of weeks on a client project and documented a few bumps I ran into and how to work around them:

I will be speaking about the overall experience of working on this project at Js VidCon in May – including why I decided against using Amplify, and why I settled on a multi-database design for DynamoDB.

I had an interesting discussion with someone on LinkedIn about the 6MB input size limit on Lambda. And I shared four different approaches for working around this limit and allow the client to go directly to S3.


I spoke at a couple of online meetups recently, you can find the recording for my talks here:


As more and more conferences and meetups are moving online, I’ll be posting more of my talks on my YouTube channel. Subscribe and click the notification bell to get notified whenever I post new talks online.

I have quite a few talks coming up in the next few weeks, all virtual, so you can enjoy them in the safety of your home!

Open source updates

I added a new s3-select-batch command to the lumigo-cli, which allows you to run an S3 Select query against all the objects with a given prefix and collect the results.

And I even recorded a short demo to show you how it works in action!
