Hi, here’s a quick round-up of everything I have done in October 2023.


We aired three episodes on the Real-World Serverless podcast:

We wrapped up the cohort of my Production-Ready Serverless workshop and we received so many great questions from the students. It was a blast working with everyone to help them through these questions. I learned a lot along the way and enjoyed brainstorming through them!

Here are some of my favourite questions:

  • How to migrate databases for a live service?
  • How best to set up IAM permissions for CI roles?
  • How to calculate the max TPS that my function can handle?
  • How to implement canary deployments?
  • How to implement multi-language support for user-generated content?
  • How to do data migration with DynamoDB?
  • What are your thoughts on fat Lambda function vs single-purposed functions?
  • How to choose between IaC tools – Serverless vs SAM vs CDK vs Terraform vs SST?
  • How to share information between Terraform (favoured by platform teams) and Serverless/CDK/SAM?
  • At what point would you consider using containers?
  • How do you deal with the FUD slingers wrt serverless?
  • How to automatically add Cognito users to an RDS database?
  • How to do cascade deletes with DynamoDB?
  • How do we automate schema migrations for RDS as part of CICD?
  • How do you implement idempotency?

The next cohort starts in January 2024. If you sign up now, you can still enjoy 30% off with our early bird tickets. The price goes up on the 1st of December.

Also, starting with the January workshop, we will be supporting CDK as well. So students would be able to choose whether to use the Serverless framework or CDK to do the exercises.

Looking ahead to November

I’m hosting a free webinar session with Waldemar Hummer, CTO of LocalStack, on some key takeaways from running and debugging serverless applications locally. It’s happening on November 9th, it’s not too late to sign up and join us.

Hope to see you around :-)
