All Your Routes Are Ready, More or Less - Dave Protasowski

Wednesday November 13, 2024 11:15am - 11:50am MST

Salt Palace | Level 1 | 155 E

Gateway API is the official next gen Kubernetes API for Ingress, Load Balancing and Service Meshes. Many proxies implement the API and pass conformance with glowing colours! But what is it really like to use the API? What isn't covered by the conformance tests that end-users should know. In the talk we'll highlight our experience adopting the Gateway API in the Knative Serving project. We'll talk about the problems we encountered and how we addressed them. Come to the talk and we'll pit some implementations against each other and show some numbers!

Cilium, eBPF, WireGuard: Can We Tame the Network Encryption Performance Gap? - Daniel Borkmann & Anton Protopopov, Isovalent

Wednesday November 13, 2024 2:30pm - 3:05pm MST

Salt Palace | Level 1 | 155 E

To increase data security for cloud and hybrid cloud deployments, many companies, governments, standards, and tenders require data in transit to be protected. However, network encryption comes at a cost - what is the performance impact and how can we reduce it? In this session, we explore how network encryption can be efficiently enforced with Cilium, eBPF, and WireGuard. We dive deep into Cilium’s integration of WireGuard and elaborate on both the management plane and Cilium’s eBPF datapath. We analyze and benchmark what performance cost one can expect and explore opportunities in the Linux kernel to reduce that price. This talk is for operators and security teams that need to encrypt network traffic, but also want to minimize its overhead. The audience will walk away understanding whether network encryption needs to come at a high toll and whether there are opportunities for optimizations.

Extending the Gateway API: The Power and Challenges of Policies - Kate Osborn, NGINX

Wednesday November 13, 2024 3:25pm - 4:00pm MST

Salt Palace | Level 1 | 155 E

From the beginning, the Gateway API has been designed to be extensible. With over 25 implementations to date, it’s crucial that these implementations have a way to support implementation-specific features without resorting to annotations. Among the various ways to extend the Gateway API, the Policy Attachment mechanism stands out as the most potent and challenging. In this session, we will explain what Policy Attachment is and share the lessons we learned at NGINX when implementing our own Policies. You will learn about: - The difference between direct and inherited policies. - How policy inheritance and merging works. - Corner cases, such as conflicting policies and invalid target refs. - Techniques to verify if a policy has been successfully applied. - Strategies for troubleshooting policies. We will show you examples of Gateway API policies as well as policies from multiple Gateway API implementations.

Harnessing the Power of Envoy Proxy for Building an LLM Gateway - Idit Levine, Solo.io

Thursday November 14, 2024 11:00am - 11:35am MST

Salt Palace | Level 1 | 155 E

As the demand for LLMs continues to soar, the need for secure, cost-conscious, and content-aware control over its usage is paramount. In this talk, we explore why Envoy Proxy is the optimal choice for building an LLM gateway, leveraging its unique architecture and capabilities. Unlike traditional proxies (e.g. NGINX), which rely on scripting languages for customization, Envoy Proxy stands out due to its extensibility features: filter architecture, callout architecture (ext-proc, ext-auth), and ability to dynamically load libraries. Combined with its high-performant, async core ( C++), Envoy can run as an ingress, egress and mesh gateway. We'll look at using Envoy proxy for LLM credential management, prompt guarding/decorting, analyzing content safety, usage controls, context-aware failover, and observability. Ideal for developers, architects, and tech enthusiasts looking to solve challenges around LLM usage and picking the right technologies for their platform infrastructure.

How to Move from Ingress to Gateway API with Minimal Hassle - Keith Mattix, Microsoft

Thursday November 14, 2024 11:55am - 12:30pm MST

Salt Palace | Level 1 | 155 E

For many, the Ingress resource was one of the first Kubernetes APIs they used, adding HTTP routing rules and SSL certs for cluster-external traffic. These APIs are used for production in clusters across the world today, configuring ingress gateways serving hundreds of thousands of connections per second. As of October 2023, the Ingress API has been superseded by the Gateway API, a new set of Kubernetes resources with over 20 implementations that enforces security best practices by design. However, migrating networking APIs is an intimidating task, and doing so safely is every company’s primary concern. Join this session to learn how to make this migration safe by identifying the best migration path, implementing Gateway API best practices, and utilizing community-supported migration tools such as ingress2gateway.

How the Tables Have Turned: Kubernetes Says Goodbye to Iptables - Casey Davenport, Tigera & Dan Winship, Red Hat

Thursday November 14, 2024 2:30pm - 3:05pm MST

Salt Palace | Level 1 | 155 E

For decades, iptables has been the preferred packet filtering system in the Linux kernel. Used extensively across the Kubernetes networking ecosystem, iptables is now on the way out and is expected to be removed from the next generation of Linux distributions. With iptables past its prime, where does that leave Kubernetes? The successor to iptables -- nftables -- is ready to carry the torch instead, with a newly released beta kube-proxy implementation in v1.31 and network policy using Calico’s nftables backend. In this talk, Dan and Casey will share what they have learned building Kubernetes Service and NetworkPolicy implementations using nftables. They will cover the history and current status of iptables usage in Kubernetes, the capabilities and performance characteristics of Kubernetes networks running on nftables, and why eBPF may not be the right tool for the job.

Kubernetes Multi-Cluster Networking 101 - Niranjan Shankar, Microsoft & Ram Vennam, Solo.io

Thursday November 14, 2024 3:25pm - 4:00pm MST

Salt Palace | Level 1 | 155 E

You’ve (somewhat) grasped the networking model of a single Kubernetes cluster. But how do you enable Pods to communicate across clusters? How do service discovery and DNS work for a multi-cluster setup? How do you secure inter-cluster traffic and manage certificates? Not sure? Don’t worry - this session will have the answers. We’ll start by outlining the core requirements for workloads to communicate across clusters. You’ll then learn some common multi-cluster networking topologies, like flat and multi-network setups, and how inter-cluster connectivity and IP address management differ for each of them. Finally, we’ll cover some popular tools for managing and securing traffic between clusters, like service mesh, CNIs, and gateways, and discuss their use-cases. You’ll leave this session with a solid understanding of fundamental terms and concepts - like virtual networking peering, external DNS, trust domains, etc - needed for navigating the multi-cluster networking landscape.

One Gateway API to Rule Them All (and in the Cluster Configure Them) - Flynn, Buoyant

Thursday November 14, 2024 5:25pm - 6:00pm MST

Salt Palace | Level 1 | 155 E

Ingress, egress, east-west, north-south… Kubernetes has always had a lot of different ways to talk about network traffic, each with its own concerns. For years, the possibility of unifying these kinds of configuration under a single API was a tantalizing but far-off possibility until Gateway API v0.8 took the first step of combining ingress and mesh configuration. Now Linkerd is stepping up to use Gateway API to handle egress as well. Join us for a hot-off-the-presses look into what egress policy covers and what people need from it, how we can make egress functionality work within Gateway API's existing model, and why Linkerd took this approach. We'll touch on the implementation and finish up with a live demo showing off a real-world example of egress management using Linkerd and Gateway API.

Seeing Double? Implementing Multicast with eBPF and Cilium - Louis DeLosSantos, Isovalent at Cisco

Friday November 15, 2024 11:55am - 12:30pm MST

Salt Palace | Level 1 | 155 E

Multicast is a popular networking technology used in finance, telecommunications, and media CDNs, among others to efficiently replicate and deliver data streams to multiple clients. However, this advantage can be overshadowed by the complexity involved in configuring the necessary infrastructure leaving the overworked platform team rather than the end users seeing double. To combat this complexity, Cilium explored using eBPF to implement pod-to-pod multicast delivery within a Kubernetes cluster. This talk will provide both a high and low level understanding of how eBPF can be used to implement multicast delivery. It will discuss how Cilium’s multicast works and the hurdles faced by the project along the way. By the end of this talk the audience will have a better understanding of how multicast functions, how eBPF can be used in-place of traditional multicast infrastructure, and how Cilium can be used as a multicast-enabled CNI, letting your audience - and not you- see double.

Testing Kubernetes Without Kubernetes: A Networking Deep Dive - John Howard, Solo.io

Friday November 15, 2024 2:00pm - 2:35pm MST

Salt Palace | Level 1 | 155 E

There are few things more tedious than waiting for a long end-to-end test to run. Waiting for a new cluster to spin up, images to build and push - not to mention things like debugging or running on slow internet connections. Unfortunately, these complex setups are hard to avoid, especially if we are testing things deeply integrated into Kubernetes networking, such as CNIs, kube-proxy, services meshes, and more. It doesn't have to be this way! In this talk, I will give a deep dive on how we built out our testing strategy for our Kubernetes networking proxy to not really depend on Kubernetes (or docker, or root). In doing so, I will not only offer a glimpse behind the scenes of Istio development, but also give viewers a deeper understand of how the fundamentals of Kubernetes (Linux primitives like namespaces) work, and how they can be effectively used to improve tests in the Istio ecosystem and beyond.

Uninterrupted gameplay with minimal network latency, jitter, and maximum throughput is crucial for a great gamer experience. But how do we maintain consistent network quality in cloud gaming production environments at NVIDIA when 2K+ players (pods) share the same physical network for game storage and streaming? When a new player joins and a pod starts downloading large contextual game data, it is vital to shield other players on the same node from this 'noisy neighbor'. Kubernetes provides limited pod-level traffic shaping but we needed more than that. In this talk we will show how we achieved true Quality of Service and wire-speed networking on Kubernetes clusters using Differentiated Services Code Point (RFC7657) markings on pod traffic. Through a live demo that will involve a noisy pod and a victim pod, attendees will gain actionable insights and best practices around packet-parameter-tuned traffic shaping using simple Kubernetes Custom Resources to optimize network performance.

With Great Flexibility Comes Great Complexity: Inspect Your Gateway API Configuration - Mattia Lavacca, Kong & Gaurav Ghildiyal, Google

Friday November 15, 2024 4:55pm - 5:30pm MST

Salt Palace | Level 1 | 155 E

With its graduation, Gateway API has emerged as the new standard for managing L4 and L7 routing within Kubernetes, as it brings in a wider set of functionalities and flexibility never seen with the ingress API, and is implemented widely for both ingress and service mesh use cases. The trade-off of having such a powerful API is additional complexity, and navigating the intricacies of Gateway API involves listing multiple resources, cross-referencing and understanding the relationships between them, and ensuring explicit authorization for all cross-namespace references - a formidable challenge, nonetheless. In this talk, Gaurav and Mattia will walk you through how to use gwctl, a command-line tool designed specifically for Gateway API (which is part of the Gateway API project itself), that works seamlessly alongside Kubectl.
