1. Event sourcing & CQRS with Django.

Django framework, together with such libraries as DRF, Celery gives us a very nice foundation to build applications in a fast and reliable manner. However, at first glance, it seems a bit challenging or counterproductive to be used with patterns like Event sourcing, CQRS, and Onion architecture. In this discussion, we will overview the building blocks of Django, go through several mentioned best practices, and discuss a few examples of how we have used them together with Django at Corner Case Technologies - from very simple to more complex solutions.

2. Mystery of AWS ALB timeouts

AWS Application Load Balancer (ALB) is a convenient way to manage traffic for your web services. At Convious - we use it in front of our python HTTP APIs. In this talk, I will try to tell a short story on how suddenly AWS ALB started misbehaving in a way that we have not managed to find any documentation or public comments. The problem have led our company onto multiple misleading debugging paths and head scratching. After many hours on it - we managed to make ALB work reliably again.
