How to build serverless apps in 2025?

Room: Yasmin-I | Time: 10:30

Let's take a look at how to build Serverless apps in 2025 and what tooling to use. The talk will focus predominantly on AWS environment, but we might also take a peek at rising stars among the cloud providers like for example CloudFlare. We will take a look at SST.dev framework/tool which is built on top of Pulumi and focuses on providing the best Developer Experience when building cloud-native applications.

Generative AI architecture patterns in production

Room: Yasmin-I | Time: 11:30

2024 has been the year of taking generative AI applications into production. Launching generative AI applications requires careful considerations around model selection and evaluations, fine-tuning versus RAG, security, privacy, hallucination control, and cost management. In this session, dive into some common architecture patterns, security guardrails, governance approaches, and optimization tricks that have been developed to support hundreds of AWS customers launch their generative AI workloads in production globally across popular use cases, like content generation, chatbots, document search, and more.

SERVERLESS-01

Event-Driven and serverless in world of IoT

Room: Yasmin-I | Time: 13:00

In large-scale IoT systems, where thousands of devices are constantly communicating, data and control messages can flow unpredictably and at varying rates throughout the day. Serverless and event-driven architectures provide a dynamic and efficient solution to this challenge. In this session, we’ll explore why serverless is a great fit for IoT, particularly in handling data ingestion and management. We’ll dive into the key architectural patterns used in IoT systems, highlighting how event-driven design enables scalability, flexibility, and cost optimization. I’ll also walk you through an architecture I designed for an IoT use case, showcasing the integration of various AWS services tailored for data ingestion, processing, and analytics. Along the way, we’ll discuss the challenges encountered and lessons learned during development, offering actionable insights into the unique aspects of building serverless IoT solutions. Join me to understand how serverless and event-driven architectures can unlock the full potential of IoT, enabling resilient and scalable systems that are easy to manage and adapt to evolving demands.

From MacBook to Bedrock: Lessons from building an AI assistant

Room: Yasmin-I | Time: 14:00

Training an AI-powered Slackbot sounds straightforward until your model starts ignoring half of the data you feed it. At AWS User Group Vienna, we built OTTO, a Slack-integrated AI assistant, fine-tuned using the open source tool InstructLab and deployed on Amazon Bedrock. But as we scaled up, we ran into real-world bottlenecks: training on MacBooks was slow, retrieval was inconsistent, and debugging was way harder than expected. This talk goes beyond the ‘perfect AI stack’ and into the messy reality of model tuning, infrastructure choices, and the unexpected lessons we learned. If you’re working on AI-powered assistants (or just curious how fast things can go sideways), this talk will provide practical insights into our approach, with focus on cost efficiency, and what we learned on the way.

Building generative AI applications that execute tasks using agents for Amazon Bedrock

Room: Yasmin-I | Time: 15:15

Agents for Amazon Bedrock enable you to build applications that can interact with your systems and data to automatically perform tasks and trigger complex workflows. Allowing you to build powerful, secure systems that are customized for your data and use case. In this session you’ll discover how to design and build genetic systems using AWS technologies. Including a demo and source code so that you can try it out for yourself!
