Session Descriptions:

Understanding AI: build your own enterprise ChatGPT with LangChain4J

In this session we will build a chatbot from based on OpenAI models and implementing the Retrieval Augmented Generation (RAG) pattern. Using a reference document database, the model will be able to answer questions in natural language and generate complete, sourced responses from your documents. To do this, we will create a Quarkus service based on the open-source LangChain4J framework and a website to test our chatbot.

Accelerating Development: Harnessing Service Bus and Azure Functions for Event-Driven Solutions

In this session, dive into the world of event-driven development with Service Bus and Azure Functions. Discover how to leverage these powerful Azure services to create robust, scalable, and responsive applications that react to events in real-time. We'll start by exploring the fundamentals of event-driven architecture and how it enables loosely coupled and highly scalable systems. You'll learn how Service Bus acts as the backbone of event communication, allowing seamless publishing and consuming of events across your application. Next, we'll delve into Azure Functions and understand how they can be used to process events triggered by Service Bus. We'll walk through real-world scenarios and explore best practices for designing and implementing event-driven solutions using Azure Functions.

Throughout the session, you'll gain practical insights and tips for designing resilient architectures, handling message processing, and optimizing performance. Whether you're building microservices, IoT applications, or real-time analytics pipelines, this session will equip you with the knowledge and tools to accelerate your development with event-driven architecture on Azure.
