How I saved 80% of Cloud Costs by using Serverless right en
Serverless promises "pay for what you use" — but what if you're using it wrong?
In this case study, I'll share how one client accidentally racked up massive costs running a simple newsletter registration system. They picked serverless for its low upfront cost, but poor architectural decisions turned it into a monthly money pit: slow cold starts, bloated packages, and 23 separate function apps running in parallel.
Together, we'll explore common serverless pitfalls that silently drain your budget, why "just scaling up" (or going premium) isn't always the answer and the importance of lightweight functions and package hygiene.
While this story unfolded on Azure Functions, these lessons apply whether you're on AWS Lambda, Google Cloud Functions, or any serverless platform. By the end, you'll walk away with practical strategies to design leaner, faster, and dramatically cheaper cloud apps — and maybe save your team from that awkward budget meeting.
Why Serverless Is the Best Choice for Your Next Greenfield Project - and How to Make It a Success en de
“Serverless First” frees teams from heavy infrastructure work so they can focus on building features that matter. But what does “serverless” really mean—and how do you know it’s right for your greenfield project?
In this session Florian Lenz will cut through the confusion, using examples like LEGO.com’s ability to handle huge global traffic and Coca-Cola’s vending machines thriving at small scale. We’ll also face the tough questions head-on, examining why Amazon Prime Video ultimately moved off a serverless model.
The takeaway: start simple, deliver quickly, and only switch approaches when your business truly needs it. By starting serverless, you gain the agility to pivot as your product grows—no wasted effort, no unnecessary baggage.
Why Serverless Is the Best Choice for Your Next Greenfield Project - and How to Make It a Success en de
„Serverless First“ befreit Teams von schwerfälligen Infrastrukturaufgaben, damit sie sich auf die Entwicklung der Kernfunktionen konzentrieren können. Aber was bedeutet „serverless“ wirklich - und woher wissen Sie, dass es das Richtige für Ihr Greenfield-Projekt ist?
In dieser Session wird Florian Lenz anhand von Beispielen wie LEGO.com und den Verkaufsautomaten von Coca-Cola für Klarheit sorgen. Wir werden uns auch den schwierigen Fragen stellen und untersuchen, warum Amazon Prime Video schließlich von einem serverlosen Modell abgerückt ist.
Simpel beginnen, schnell liefern und nur für das bezahlen, was man wirklich braucht. Wenn Sie mit einem serverlosen Modell starten, haben Sie die Flexibilität, Ihr Produkt mit Ihrem Wachstum zu verändern - kein unnötiger Aufwand, kein unnötiger Ballast.
Building Ultra-Fast, Globally Distributed Apps with Serverless at the Edge en
How do you build globally distributed applications that respond at lightning speed and delight users around the world - without getting lost in the server and infrastructure jungle? In this session, Florian Lenz will show how serverless technologies and edge computing go hand in hand to create ultra-fast, scalable applications. Using concrete code examples and practical best practices, attendees will learn how to bring their applications closer to the end user while simplifying deployment. We will explore the opportunities and challenges of combining serverless and edge, including creative ideas for your next projects. After this session, you'll have a clear roadmap for pushing the boundaries in the cloud era to achieve new levels of performance and global reach.
Unleash .NET Aspire: Build Cloud‑Native .NET Apps Without Infrastructure Overhead en
In this hands-on session, you'll see a complete cloud-native workflow come to life in less than 15 minutes - no infrastructure scripting required. Florian will start by building a brand new application with .NET Aspire from scratch, then running it locally to demonstrate how .NET Aspire's zero-boilerplate conventions instantly wire up service discovery, configuration, elasticity, and telemetry. Next, you'll see how a single Azure Developer CLI command can provision all the necessary Azure resources and deploy your service to Azure Container Apps. Throughout the demo, you'll see how .NET Aspire abstracts away servers, containers, and YAML so you can focus on code and business logic.
By the end of the session, you'll understand exactly how .NET Aspire transform cloud-native development into a smooth, developer-first experience - enabling you to get features into production faster, with zero infrastructure overhead. Whether you're building your first cloud service or modernizing existing .NET workloads, you'll walk away with the confidence and know-how to go from code to cloud in a single step.
Next-Gen Cloud Native .NET Apps: Aspire and Dapr Unleashed en
Are you ready to level up your .NET cloud-native game? In this action-packed session, Florian Lenz will take you on a deep dive into how .NET Aspire and Dapr together eliminate ops friction and let you focus on shipping business value—faster than ever before.
Many teams spend 50–70% of their development cycle wrestling with infrastructure and configuration. What if you could reclaim that time to innovate on features, not YAML?
By the end of this session, you’ll walk away with a reproducible, lightning-fast cloud-native workflow that empowers your teams to deliver more features, reduce risk, and delight users. Bring your questions—this will be a highly interactive, code-first talk with plenty of time for hands-on tips.
Join us to see how .NET Aspire and Dapr together redefine what “cloud-native” means for .NET developers.
Under the Hood of Azure Durable Functions: Understanding the Internals en
Take an expert-level deep dive into the core architecture and execution model that powers Azure Durable Functions. In this session, Florian Lenz will explore how the Durable Task Framework uses event sourcing to persist orchestration state, replay history, and checkpoint activities to ensure reliable, long-running workflows. You’ll gain insight into the deterministic replay engine, learn why activities must be idempotent, and see how race conditions are avoided during state reconstruction.
We’ll pull back the curtain on the backend—examining the Durable Task Scheduler’s role in queuing and distributing work items, how it interacts for event buffering, and the mechanics of orchestrator and activity worker coordination. You’ll understand how the Functions scale controller leverages the scheduler and storage metrics to scale out orchestrations safely, and how to tune checkpoint frequency, throttle fan‐out, and manage storage throughput to optimize performance and cost.
Finally, we will cover real-world troubleshooting strategies for stuck orchestrations, runaway replay loops, and excessive storage costs. By the end of this session, you’ll have a clear mental model of Durable Functions under the covers and be equipped to build, monitor, and optimize resilient, high-scale workflows in Azure.
