Integrating k8gb with any Ingress Controller via the Gateway API
The k8gb project now integrates with Gateway API configuration, enabling powerful load balancing for applications exposed through virtually any ingress controller.
In this interactive session, participants will expose various types of applications, such as HTTP, HTTPS, and TCP, using the Gateway API. These applications will then be integrated with k8gb to achieve advanced multi-cluster traffic management. While an ingress controller will be provided for demonstration purposes, participants are welcome to bring their own. The session facilitators will assist in integrating any ingress controller with k8gb to showcase its versatility.
Attendees will gain a solid understanding of the core concepts behind k8gb and its integration with the Gateway API. During the session, we may discover user setups that are not yet fully supported, providing a unique opportunity to collaborate and find solutions in real time, ultimately contributing to the advancement of the k8gb project.
Elevate Your Infrastructure - Exploring Crossplane's Full Potential
Crossplane (https://www.crossplane.io/) and its user experience has matured greatly over the years and there are now numerous layers you can interact with while designing and building your internal developer platform powered by Crossplane. Should you directly declare the cloud resources you want Crossplane to create, should you create developer friendly simplified abstractions on top, should you stick with YAML or use a more full featured high level programming language? We will explore each of these layers in further detail through live demos to understand and efficiently harness the capabilities and experience of each. This will be a broad tour through the possibilities offered by Crossplane, all of which lead to a reliable and robust control plane to manage everything in the cloud that your organization could need!
Multi-Cloud Global Content Distribution at Cloud Native Speeds
If you’ve been globally distributing digital content for a while, you’ll understand that merely having numerous datacenters with advanced caching patterns isn’t sufficient.
When your users need to retrieve an object that’s available in different locations worldwide, they should ideally be directed automatically to the location that’s nearest and fastest for the best experience. Cloud service providers typically offer services to handle this for you within their own clouds, but what if you are running a multi-cloud or hybrid environment?
K8GB is a cloud-native solution that handles GeoDNS across heterogeneous environments and enables you to reach the same level of multiregion service resilience offered by cloud providers.
Testing and Release Patterns for Crossplane
Crossplane has become the foundation of many Internal Developer Platforms (IDPs). A requirement for any IDP in production is the ability to make changes and upgrades to the platform with confidence.
This talk will cover testing and release patterns based on our experience building production-ready environments across a range of Crossplane users.
We’ll cover the lifecycle of a Crossplane Composition upgrade, from local commit to pull request to target customer environment, end-to-end testing tools, handling API changes, and how to control updates to customer environments.
For quite a while, testing Crossplane Compositions meant relying exclusively on costly end-to-end layers. In this talk, we're unveiling new unit testing capabilities that allow you to evaluate and test your Composition code in complete isolation.
Resilient Multiregion Global Control Planes with Crossplane and k8gb
Ensuring resilience in control planes is critical for organizations managing infrastructure and applications across multiple regions with Kubernetes. This talk presents a reference architecture for creating a Crossplane-based Global Control Plane, enhanced with k8gb for DNS-based failover and leveraging an Active/Passive setup.
We’ll explore how Crossplane’s declarative infrastructure provisioning integrates with k8gb to build robust, scalable, and resilient multicluster environments. Key takeaways include:
- Architecting resilient multiregion control planes with Active/Passive roles
- Demonstrating failover mechanisms where the Passive control plane transitions to Active during failures
- Strategies for optimizing failover times while maintaining availability
This session will guide attendees through proven methods and real-world challenges of building resilient Global Control Planes, empowering them to manage critical workloads across geographically distributed regions confidently.
k8gb: Global Load Balancing, the Kubernetes Way
Discover how the k8gb project brings global load balancing to Kubernetes clusters. This talk will introduce the k8gb project, highlighting its core features such as global load balancing, high availability, seamless failover, and its new extensibility feature that allows integration with various resources like Gateways and non-HTTP Services. Learn about its architecture, real-world use cases, future plans, and how you can get involved.
k8gb Contribfest: Enhancing k8gb Project with Arbitrary Network Resource Integration
The k8gb project is entering a new era of extensibility with the ability to integrate with arbitrary network resources. Recently, we decoupled our strong dependency on standard Ingress, opening new pathways for various integrations such as Gateways and non-HTTP Services. In this iteration of Contribfest, participants will execute the flow of integrating a new resource type to be globally load-balanced.

We will go through core elements that can enable successful project contributions.
* Multicluster k8gb local setup
* end-to-end test framework
* CI pipeline layout
* Executing example contribution flow
Building Air-Gapped Control Planes for a Global Pharma Leader Using Crossplane and ArgoCD
Operating in air-gapped environments imposes strict limitations on connectivity, security and compliance. This session tells the story of designing and implementing a secure, air-gapped control plane setup for Novo Nordisk, one of the world’s largest pharmaceutical companies, leveraging Crossplane for declarative infrastructure management and ArgoCD for GitOps workflows.
We’ll share how Novo Nordisk adopted and scaled the setup within their highly regulated environment:
-Architectural decisions tailored to the demands of the pharmaceutical industry
-Overcoming challenges related to security, scalability, and operational efficiency
-Strategies to replicate GitOps workflows in disconnected systems while maintaining the integrity of continuous delivery pipelines
The talk will dive deep into the technical challenges and solutions, focusing on how open-source tools like Crossplane and ArgoCD can be adapted for highly controlled environments without compromising functionality or flexibility.
Building a Cloud-Native IaC Platform for an Enterprise by leveraging the Kubernetes ecosystem
Infrastructure teams have long been a staple of large enterprises, responsible for creating and managing cloud and on-premises resources. However, each team often operates with its own user interface, making it difficult for developers to access the infrastructure they need efficiently. How can we enhance the developer experience while enabling infrastructure teams to offer products more effectively?
This talk will showcase how Allianz Technology leverages the Kubernetes ecosystem and open-source software to build an infrastructure-as-code platform powered by over 1,000 Kubernetes control planes. This approach simplifies the developer experience through customized APIs while providing infrastructure engineers with a scalable framework for delivering infrastructure products and gaining insights for continuous improvement.
