Updated: Oct 28, 2023


AWS re:Invent 2023
AWS re:Invent 2023

In this post, you will find my opinionated list of AWS re:invent 23 breakout sessions, workshops, builder sessions, code-talks, and chalk talks that I found relevant to serverless and Python developers.

As there are several hundreds of sessions, I might have missed a couple of sessions, so please let me know via ran.isenberg@ranthebuilder.cloud if I should include another session.


Please note that some sessions might not appear on the catalog's website YET, but only through the catalog's API.


The complete catalog can be found at:

 

Table of Contents

 

Session Types

As described here:

Breakout sessions - lecture-style and run 45 to 60 minutes. Often includes 10–15 minutes of Q&A.


Builders' sessions - These one-hour hands-on sessions have ten attendees and one AWS expert per table. Each builders’ session begins with a short explanation or demo of what you are going to build. There is no formal presentation. It’s just you, your laptop, and the AWS expert.


Chalk talks - highly interactive whiteboarding sessions with AWS experts. Expect a lively technical discussion, centered around real-world architecture challenges, with a small group of experts and peers. These sessions run for 60 minutes.


Workshops - a two-hour interactive sessions where you work in small teams to solve real problems using AWS services. Each workshop starts with a short lecture (10 to 15 minutes) by the main speaker, and the rest of the time is spent working as a group. Don't forget to bring your laptop to these workshops.


Code Talk - Engaging, code-focused sessions with a small audience. AWS experts lead a live coding discussion as they explain the why behind AWS solutions.

 

Session Levels

There are four levels: 100, 200, 300, and 400.

The 100-200 (Foundational & Intermediate) levels are excellent if you are a serverless beginner.

If you build serverless applications daily, target the 300-400 (advanced & expert) levels and only go to 100-200 for sessions in unfamiliar subjects (perhaps containers, data-related, or machine learning).


Let's go over the recommended sessions.

 

My Breakout Session


OPN305 | Breakout | The pragmatic serverless Python developer

I'm thrilled to share that I will be co-presenting a breakout session at AWS re:Invent 2023 in Las Vegas alongside the brilliant Heitor Lessa from AWS Lambda Powertools.
