Dapr + Score: Mixing the Perfect Cocktail for an Enhanced Developer Experience - Mathieu Benoit, Humanitec & Kendall Roden, Diagrid

Wednesday April 2, 2025 11:15 - 11:45 BST

Level 1 | Hall Entrance N10 | Room H

Developer Experience (DevEx) is an important concept in Platform Engineering and in the cloud native space, advocating for self-service and reduced cognitive load. Its primary goal is to empower developers, allowing them to focus on coding rather than fighting with infrastructure intricacies. What is the right level of abstraction? Which type of tooling is essential? How can teams identify the concepts and workflows that drive value and success?
Tools such as Dapr and Score are being used in innovative ways to make a wider range of developers more productive. On one hand, they allow the Developers to be abstracted from underlying infrastructure and dependencies. On the other hand, Platform Engineers can easily configure the building blocks and associated infrastructure, seamlessly for the Developers.
This talk demonstrates a practical blueprint between Dapr and Score, where you will see how to deploy any Dapr containerized workloads defined by Score, to Docker Compose or Kubernetes.

Workload Identity for Humans: A Twelve-Factor Approach - Vish Abrams, Heroku

Thursday April 3, 2025 17:30 - 18:00 BST

Level 1 | Hall Entrance N10 | Room E

Workload identity in cloud-native systems has largely focused on platform tools. Kubernetes Service Accounts and SPIFFE/SPIRE provide powerful identity primitives, but their flexibility results in bespoke implementations of workload identity from the perspective of the application. This forces application developers to implement custom identity mechanisms for each platform. This talk introduces a more developer-friendly approach. We layer an application-focused workload identity on top of existing CNCF solutions, focusing on simplicity and usability. Drawing on the principles of Twelve-Factor Applications, we will explore how to integrate workload identity into cloud-native applications in a way that feels natural and productive for developers. Attendees will learn practical patterns for incorporating workload identity, gain a clearer understanding of workload identity concepts, and leave with actionable strategies to improve security without sacrificing developer experience.

Type-safe Feature Flagging in OpenFeature: Lessons Learned From Using Feature Flags at Google - Michael Beemer, Dynatrace & Florin-Mihai Anghel, Google

Friday April 4, 2025 11:45 - 12:15 BST

Level 1 | Hall Entrance N10 | Room H

Feature flags are a great way to release software faster while minimizing deployment risks. They allow for controlled releases of new or complex features. However, a common issue with most feature flag SDKs in use today is that they rely on hardcoded strings to identify feature flags, leaving code vulnerable to typos or references to stale flags. This can lead to a mismatch between flags used in code and flags configured in your flag management system, resulting in unexpected application behavior.

In this talk, we will discuss a solution to this challenge using OpenFeature, a vendor-agnostic, community-driven API for feature flagging. Inspired by lessons learned at Google, we've designed the OpenFeature CLI to seamlessly integrate into your development workflow. We'll demonstrate how strongly typed feature flag accessors, created with the CLI, can be used to overcome these issues while also significantly improving the developer experience.

Failure Is Not an Option: Durable Execution + Dapr = 🚀 - Marc Duiker, Diagrid

Friday April 4, 2025 13:45 - 14:15 BST

Level 0 | ICC Capital Hall | Room 1

Applications break all the time, there could be a network issue, a cloud provider outage, or just a glitch in the matrix. But as a developer, you really need your applications to be resilient without the need to recover databases and restart services manually.

In this session, I'll demonstrate how Dapr Workflow provides durable execution, which enables you to write reliable workflows as code. In addition, I'll show how resiliency policies in Dapr improve reliable communication across services and resources when developing distributed applications.

I'll go into specific workflow features, such as scheduling, sequential and parallel execution, and waiting for external events. I'll show many code samples (in C#) for each of these features and will run the applications using the Dapr CLI to demonstrate their resiliency.

By the end of the session, you will have a good grasp of how durable execution with Dapr workflow and resiliency policies can help you build resilient applications.

Are You Covered? Falling in Love With E2E Testing - Scott McAllister, ngrok

Friday April 4, 2025 14:30 - 15:00 BST

Level 0 | ICC Capital Hall | Room 1

Automated testing aims to give us confidence that our code will run as expected in every situation–especially when we push changes. Good tests will increase your team's velocity of developing new features and reduce the headache of bugs and outages.

As more applications shift to containerized environments, testing them becomes more complex. Not only does the application code need to be tested, but so does the Kubernetes manifests. This session will clarify setting up and running automated tests in these environments. We'll discuss organizing tests in containers, handling dependencies, and maintaining consistent testing throughout the deployment process.

The session will cover setting up containers for replicable test environments, Argo CD for GitOps automation, and utilizing k3s to manage complex, interdependent test workflows, ensuring consistent, reliable end-to-end testing.

Breaking Barriers: Bringing Application Developers Closer To the CNCF - Thomas Vitale, Systematic & Mauricio "Salaboy" Salatino, Diagrid

Friday April 4, 2025 14:30 - 15:00 BST

Level 1 | Hall Entrance N10 | Room E

Being an application developer in the cloud native age is challenging. Developers new to cloud native who land on the CNCF Landscape feel overwhelmed. When using a platform that doesn’t consider the developer experience, things can get even worse. But it doesn’t have to be that way. The solution lies in the cloud native ecosystem itself.

This session covers 5 friction points that developers face and presents solutions with cloud native tools.

- Unreproducible Dev Environment. Do you need a cloud environment? Or can you run everything locally?
- Inefficient Project Onboarding and Collaboration. How do teams share configurations, tools, and common practices?
- Cumbersome Inner Dev Loop. How do you achieve efficient development workflows?
- Complex Service Integrations. How can you integrate external services without worrying about infrastructure concerns?
- Kubernetes Steep Learning Curve. Do you need Kubernetes in your local environment? How can you build production-ready containers?

AI Beyond Autocomplete: Using LLMs To Create 1000 Kubernetes Controllers - Justin Santa Barbara & Walter Fender, Google

Friday April 4, 2025 15:15 - 15:45 BST

Level 0 | ICC Capital Hall | Room 1

LLMs can generate React apps, poems, and even music. But can they rise to the ultimate challenge: writing reliable Kubernetes controllers? The Config Connector team say "yes!" We are successfully using AI to write production controllers for a thousand google cloud resources.

Our path was to first break the problem into LLM-friendly steps (such as generating KRM types, the mocks and the reconciler). For each step, we invoke custom fine-tuned LLMs in a novel way with custom “jigs”. We add testing to create an “interlock” that mitigates hallucinations.

This journey changed our whole codebase philosophy: from optimizing for lines of code, we now prioritize the ability to safely and easily author and merge focused changes (at the expense of having lots of code). Although AI motivated this trade-off, it also aids development as OSS.

We believe our approach is generally applicable; join us to learn lessons that will apply as your project embraces the AI-assisted future.

Authz as a Dev Workflow: Architecting Better Cloud Native Apps - Dan "phrawzty" Maher, Cerbos

Friday April 4, 2025 15:15 - 15:45 BST

Level 1 | Hall Entrance S10 | Room C

Every request in a cloud-native application needs authorization, but let's be honest: most developers see it as a pain-point rather than an advantage. This talk explores why authorization belongs in your application's critical path, and how making it a core part of the development process improves developer experience.
We'll look at how CNCF authorization projects and open standards from the OpenID Foundation are rethinking authorization from the ground up. Through real-world examples, we'll show how modern authorization patterns fit into existing workflows, help catch access control bugs early, and make developers' lives easier.
Attendees will leave with practical patterns for building maintainable access control logic, strategies for testing authorization rules effectively, and proven approaches for embedding security into your development workflow from the start. Whether you're building new systems or improving existing ones, you'll learn how to make authorization work for you.

Friday April 4, 2025 15:15 - 15:45 BST

Level 1 | Hall Entrance N10 | Room E

Restartability is key for cloud-native applications to leverage Kubernetes' core capabilities, including self-healing, automated rollouts, autoscaling, and maintenance eviction. However, achieving robust restartability requires careful application design and precise Kubernetes manifest configurations.

In this session, we will dive into Pod restartability with two practical demonstrations: "HTTP Server" and "Operator with Leader Election". Key topics include:
- The Pod lifecycle focuses on request handling during startup and termination.
- How health probes (readiness, liveness, and startup) change Pod behavior.
- Signal handling and a graceful shutdown implementation.
- Best practices for Pod Disruption Budgets (PDBs) and their common pitfalls

By the end, you’ll gain actionable insights to make your cloud-native applications more resilient, fully aligned with Kubernetes’ self-healing capabilities, and ready for seamless restarts with minimal downtime.
