Kubernetes Workspaces: Enhancing Multi-Tenancy with Intelligent Apiserver Proxying - James Munnelly & Andrea Tosatto, Apple

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

Salt Palace | Level 2 | 255 B

Multi-tenancy in Kubernetes means sacrificing essential features like cluster-scoped list/watches and multi-namespace/cluster-scoped RBAC. This often leads to additional complexity when configuring operators and forces discrepancies and friction with cluster-as-a-service type offerings. In this talk we will go through a demonstration of an intelligent Kubernetes apiserver proxy that introduces the concept of a ‘workspace’. Borrowing the name from the KCP project, a Workspace is a virtual apiserver endpoint that provides a ‘cluster-scoped’ view over a group of namespaces in a remote cluster. We’ll then go on to discuss optimisations and changes that we’d like to make within Kubernetes to better support apiserver proxying for multi-tiered caching, routing and scoping purposes.

Running Quantum-Safe Applications on Kubernetes - Paul Schweigert & Michael Maximilien, IBM Quantum

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

Salt Palace | Level 2 | 255 B

Quantum computers pose a unique threat to computer security, as the encryption standards we rely upon are vulnerable to powerful quantum computers. While those computers are still several years away, "harvest now, decrypt later" attacks put all data not protected using quantum-safe security at risk. So what can we do now to protect our applications? In this talk, Paul will demo how to deploy a quantum-safe application on Kubernetes. He'll provide a brief overview of quantum-safe cryptography and why it's needed, highlight key work being done in the open source community to migrate to quantum-safe cryptography, and conclude with a demo of how to build a quantum-safe cloud-native application. In particular, he'll show where and how to make changes to a Kubernetes environment to ensure users are protected by quantum-safe connections. At the conclusion of this session, listeners will have a set of practical steps they can take to help secure their applications in a post-quantum world.

Running WebAssembly (Wasm) Workloads Side-by-Side with Container Workloads - Jiaxiao Zhou, Microsoft

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

Salt Palace | Level 2 | 255 B

Sidecar containers are a powerful Kubernetes design pattern, running alongside the main application within the same pod to provide supporting features like observability, configuration and communication. However, sidecars can be resource-intensive, adding up to high CPU, memory and network bandwidth usage. WebAssembly (Wasm) offers a solution with its low resource usage and minimal memory footprint compared to Linux containers. Its quick start-up time enables scale-to-zero capability, making it a perfect fit for sidecar containers. The Containerd Runwasi project extends the sidecar pattern by enabling Kubernetes-native deployment and management of Wasm workloads.This talk will show how you can get started deploying Wasm sidecars to support your primary services with additional functionality. It will conclude with a demo of integrating these Wasm sidecars with your existing sidecar framework, whether that be Service Mesh or Dapr. Tune in to see Wasm sidecars on Kubernetes!

Load-Aware GPU Fractioning for LLM Inference on Kubernetes - Olivier Tardieu & Yue Zhu, IBM

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

Salt Palace | Level 2 | 255 B

As the popularity of Large Language Models (LLMs) grows, LLM serving systems face challenges in efficiently utilizing GPUs on Kubernetes. In many cases, dedicating an entire GPU to a small or unpopular model is a waste, however understanding the relationship between request load and resource requirements has been difficult. This talk will study GPU compute and memory requirements for LLM inference servers, like vLLM, revealing an analytical relationship between key configuration parameters and performance metrics such as throughput and latency. This novel understanding makes it possible to decide at deployment time an optimal GPU fraction based on the model's characteristics and estimated load. We will demo an open-source controller capable of intercepting inference runtime deployments on Kubernetes to automatically replace requests for whole GPUs with fractional requests using MIG (Multi-Instance GPU) slices, increasing density hence LLM sustainability without sacrificing SLOs.

WASM + KWOK Wizardry: Writing and Testing Scheduler Plugins at Scale - Dejan Pejchev & Jonathan Giannuzzi, G-Research

Thursday November 14, 2024 4:30pm - 5:05pm MST

Salt Palace | Level 2 | 255 B

Zoom Link

In the world of Kubernetes, optimizing scheduler performance is key to maximizing cluster efficiency. This session dives into building custom Kubernetes scheduler plugins using WebAssembly and leveraging KWOK to test their performance. We'll begin by introducing the fundamentals of Kubernetes scheduling and the unique advantages of WebAssembly, such as fast startup times and secure sandboxing. We will show how the kube-scheduler-wasm-extension project can be used to create custom scheduling logic easily. Next, we'll explore KWOK (Kubernetes WithOut Kubelet), a tool that simulates Kubernetes clusters for testing and benchmarking purposes. Through hands-on examples, we'll demonstrate how to set up KWOK, create realistic test environments, and gather performance metrics to fine-tune your custom scheduler plugins.

What if Kubernetes Was a Compiler Target? - David Morrison, Applied Computing Research Labs & Tim Goodwin, UC Santa Cruz

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

Salt Palace | Level 2 | 255 B

Multi-tier programming is a classic concept from the programming languages community, which provides abstractions for building multiple layers of a distributed application at once. For example, there might be a “presentation” tier that displays a user interface, a “data” tier that interacts with a backing database, and a “business logic” tier that connects the two, all of which can be expressed succinctly as part of the same program and compiled into independently-deployable units. However, Kubernetes has pushed modern software development in the opposite direction: SOA applications are composed of hundreds of independent units of code, often written in different languages and development environments. In this talk we provide an overview of multi-tier programming and how it might apply to software development on Kubernetes. We also present a prototype “Kubernetes compiler” that can turn a monolithic codebase into a distributed application that runs on top of Kubernetes.
