Platform Engineering Vienna - December 2025 Meetup

Time passes incredibly fast and we have already arrived at the our last event of 2025. Welcome to our December/Christmas edition 🎄! Join us - at the Dynatrace office - for the last time this year for great talks, some beers and a super secret surprise at the end.

Agenda:

• Doors open 5:30 p.m.
• Talk 1: 6:00 to 6:30 p.m.
• Speaker: Christian Kirchknopf
• Title: Building a Secure In-House LLMaaS Platform: BRZ's Approach to AI for Federal Government
• Abstract: In this talk, I demonstrate how we (BRZ) have developed an Enterprise-Ready LLM-as-a-Service platform that provides government applications simple and secure access to Large Language Models – without dependency on public cloud providers and without data sharing with third parties.
  Through a unified API, AI applications gain access to locally operated models (e.g., Mistral) or optionally to public cloud providers – depending on requirements, costs, and data protection needs of the workload.
  Discuss the architectural and product decisions: vLLM as a GPU-optimized inference engine, a central AI gateway that enforces multi-tenancy, security, and comprehensive observability.
  A brief live demo will show how applications and developers access AI models through a single API – with token-based quotas per tenant and intelligent routing.
  An experience report from an exciting AI infrastructure project in Austria.
• Break: 6:30 to 6:45 p.m.
• Talk 2: 6:45 to 7:30 p.m.
• Speaker: Juliano Costa
• Title: Smells Like Clean Telemetry: Stop the Noise, Create Better Spans
• Abstract: You’ve heard about OpenTelemetry for observability and how important the topic is when thinking about services and platforms. Now it’s time to give it a shot. Instrumenting your services was easy—until it wasn’t. You got some traces flowing into your observability backend, but as soon as you started adding custom spans and attributes, the real questions began.
  Should you create spans for every single method/function in your code? Is more always better? What attributes should you add to your spans? Maybe include full JSON payloads, or go all out and add a whole PDF as an attribute? (Spoiler: don’t.)
  Join Juliano in this talk to learn best practices for customizing your application instrumentation with OpenTelemetry. Discover how to make the most of your telemetry while ensuring usability, cost efficiency, and performance. Whether you're just starting out or fine-tuning your instrumentation, this session will help you get to the right balance, avoid costly mistakes, and walk away with clear strategies to get the most out of your telemetry.
• Secret surprise: 7:30 to 7:45 p.m.
• Networking: start 7:45 p.m.
