Demystifying Kubernetes Gateway API: From Ingress to Modern Traffic Management
For years, the Ingress API has been the standard way to expose applications running in Kubernetes. As deployments became more sophisticated, however, Ingress often relied on controller-specific annotations and custom extensions, making traffic management difficult to understand, maintain, and standardize across environments.
The Gateway API was created to address these challenges. As the next generation of Kubernetes traffic management, it provides a more expressive, extensible, and role-oriented approach to routing traffic into and within clusters.
This session offers a practical introduction to the Gateway API for platform engineers, developers, and Kubernetes users who want to understand the new standard without getting lost in the terminology. We will explore the core concepts behind GatewayClass, Gateway, and Routes, and see how they enable a clear separation of responsibilities between cluster administrators and application teams.
Through straightforward examples and comparisons with the traditional Ingress model, attendees will learn why the Gateway API was introduced, how it differs from Ingress, and how it simplifies the management of modern Kubernetes networking. By the end of the session, participants will have a solid foundation for understanding and adopting the Gateway API in their own environments.
Gateway API: The Illustrated Guide to the Future of Kubernetes Networking
Gateway API is the future of Kubernetes networking, replacing the chaos of Ingress annotations with a structured approach. Instead of boring slides, this talk is structured as a Wizard Zine -- a visual guide you can take home.
We will cover the Gateway API from two perspectives:
1. User View: Understanding the GatewayClass -> Gateway -> Route hierarchy and how role separation between admins and developers saves sanity.
2. Developer View: A look under the hood of a controller. I will show what happens inside: from watching CRDs to generating data plane rules, and why resource status is critical.
You will leave with deep technical knowledge and a digital cheat sheet (zine) that makes mastering the Gateway API an engaging journey.
Keep your mind open, and keep the gateway open!
Trash Talk: Stacks, Heaps, and the Art of Garbage Collection
As a software developer, I strive to write fast, resource-efficient code. While benchmarking, I noticed unexpected slowdowns -- something was off with memory allocations. That realization led me down the rabbit hole of memory management.
Memory is finite, and mismanagement can lead to leaks, crashes, and poor performance. Garbage collection (GC) automates this process, but it comes with trade-offs. Go’s GC is designed for efficiency and low latency, but understanding its inner workings helps write better code.
In this talk, we’ll explore:
- Stack vs. heap allocations and why one is slower.
- What data is stored where.
- Escape analysis: how Go decides memory placement.
- How Go GC works and its impact on performance.
- Practical GC tuning strategies for optimizing applications.
By the end, you'll gain a deeper understanding of Go’s memory model and techniques to optimize your applications.
Deep dive into the HCP Terraform kubernetes operator
In this deep dive, we’ll explore the architecture, key features, and lessons learned during the development of the HCP Terraform Kubernetes Operator.
We’ll unpack its design principles, examine how it automates operational tasks, and discuss the challenges tackled during its creation, including performance optimizations and user experience improvements. Along the way, we’ll share insights gained from real-world use cases and highlight best practices for leveraging the Operator in your cloud-native environments.
Whether you’re an Operator developer, a Kubernetes enthusiast, or a Terraform user, this session will provide valuable insights into building and using tools that simplify infrastructure management.
