Speaker & Talk Information

Marius Stein: Dungeons and Dragons, AI-Chatbots and the intricacies of RAG - An open discussion
Join us for an engaging session where we introduce Ellie, an open-source Dungeons and Dragons chatbot built using LangChain and Retrieval-Augmented Generation (RAG). We'll use Ellie as a case study to explore the challenges and solutions encountered during the development of a RAG-based chatbot. This interactive session encourages attendees to share their own experiences and insights into creating RAG-based chatbots.

Vadym Kazulkin: How to develop, run and optimize Spring Boot 3 application on AWS Lambda
In this talk I will present and compare several options of how to run Spring Boot 3 application on AWS Lambda using AWS Serverless Java Container, Spring Cloud Function, AWS Lambda Web Adapter and Custom Docker Image. I'll also discuss strategies how to optimize cold start of such Lambda function with AWS Custom Lambda Runtime based on GraalVM Native Image and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. Is Spring Boot native support of CRaC also a potential optimization? I'll also present various (SnapStart) priming techniques to reduce the cold start even further.
