Advanced Model Serving Techniques with Ray on Kubernetes - Andrew Sy Kim, Google & Kai-Hsun Chen, Anyscale
Wednesday November 13, 2024 11:15am - 11:50am MST
Salt Palace | Level 2 | 255 B
With the proliferation of Large Language Models, Ray, a distributed open-source framework for scaling AI/ML, has developed many advanced techniques for serving LLMs in a distributed environment. In this session, Andrew Sy Kim and Kai-Hsun Chen will provide an in-depth exploration of advanced model serving techniques using Ray, covering model composition, model multiplexing and fractional GPU scheduling. Additionally, they will discuss ongoing initiatives in Ray focused on GPU-native communication, which, when combined with Kubernetes DRA, offers a scalable approach to tensor parallelism, a technique used to fit large models across multiple GPUs. Finally, they will present a live demo, demonstrating how KubeRay enables the practical application of these techniques to real-world LLM deployments on Kubernetes. The demo will showcase Ray’s powerful capabilities to scale, compose and orchestrate popular open-source models across a diverse set of hardware accelerators and failure domains.

Unlocking Cost Savings & New Possibilities: Your Guide to Prometheus Remote Write 2.0 - Callum Styan, Grafana Labs & Bartłomiej Płotka, Google
Wednesday November 13, 2024 11:15am - 11:50am MST
Salt Palace | Level 1 | Grand Ballroom B
Prometheus Remote Write is the protocol used to send Prometheus metrics from Prometheus or any other metric source to compatible remote storage endpoints such as Thanos and Cortex. Remote Write is generally used for metric long term storage, centralization, and cloud services. It also enables users to run Prometheus in an agent mode, reducing local storage requirements. Welcome to Remote Write 2.0! In this talk, Bartek and Callum, Prometheus maintainers and RW2.0 spec. co-authors, will introduce you to the next iteration of the popular protocol which adds more functionality while cutting your egress costs up to 60%, and keeps the previous versions easy-to-implement stateless design! The audience will learn what's changed in the second version of Remote Write, what it unlocks, and how easy it is to update or adopt. Finally, the speakers will share the latest benchmarks and differences with the common alternatives.

Building Reliable Cross-Cloud Kubernetes Clusters on Spot Instances with Drafter and PVM - Felicitas Pojtinger, Loophole Labs
Wednesday November 13, 2024 12:10pm - 12:45pm MST
Salt Palace | Level 2 | 254 B
Building Kubernetes clusters that span across multiple cloud providers prevents vendor lock-in and offers flexibility. Using spot instances can further cut costs by up to 90%, but they can terminate with only 30 seconds' notice. Traditionally, migrating VMs across cloud providers and CPUs to mitigate this has been challenging due to hardware constraints. PVM (Pagetable Virtual Machine) is an experimental kernel technology that changes this by enabling KVM without hardware assistance or emulation. Using the research paper, this session will explain how PVM works and how the open-source Drafter and Firecracker projects can use it to migrate VMs between cloud providers. The session includes a live demo of running Kubernetes components like the Kubelet, CRI, CSI and CNI inside VMs and migrating them in a heterogeneous EC2, GCP, and Azure environment. This allows evacuating a Kubernetes node and network without downtime if a spot instance is terminated or if another provider is cheaper.

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.

Bridging Clouds: TikTok’s Blueprint for Unified OIDC Access on Multi-Cloud Kubernetes - Naveen Mogulla, TikTok
Wednesday November 13, 2024 2:30pm - 3:05pm MST
Salt Palace | Level 1 | 151 G
As businesses embrace increasingly complex multi-cloud environments, managing access across diverse Kubernetes setups becomes paramount. At TikTok, we faced the challenge of unifying OpenID Connect (OIDC) access for Kubernetes clusters across GKE, EKS, OKE and on-prem clusters each providing different levels of support and integration. This talk will detail our journey to develop a scalable, centralized OIDC framework using a reverse proxy approach, ensuring seamless authentication and authorization across different cloud providers. We will discuss our architectural strategy, highlighting how we leveraged Envoy for request handling and dynamic configuration with external authorization filters to accommodate diverse OIDC implementations. Discover how TikTok overcame identifying OIDC discrepancies among providers to implementing a unified solution that not only simplifies k8s access management but also reinforces security and compliance across our global, multi-cloud infrastructure.

Deep Dive Into Generic Control Planes and Kcp - Stefan Schimanski, Upbound & Mangirdas Judeikis, Cast AI
Wednesday November 13, 2024 3:25pm - 4:00pm MST
Salt Palace | Level 2 | 254 B
The Kubernetes code now allows native construction of generic control planes, without container types and in new form-factors other than your beloved clusters, be it customized apiserver binaries or embedded into other applications. This talk gives an in-depth explanation of what a generic controlplane is, how to construct it, how to extend it with custom types and how to control which native Kube APIs like secrets, configmaps, etc. or mechanisms like resource quota or RBAC are available. Specifically, we will cover 3 variants: 1. single-tenant generic control planes using upstream Kubernetes. 2. multi-tenant generic control planes using kcp to scale horizontally in one process. 3. multi-shard and multi-region generic control planes with focus of backing SaaS services.

Kubernetes at Scale: Practical Solutions for Enhanced CNI and Kubelet Performance - Henrique Santana, Amazon Web Services & Bruno Gabriel da Silva, Sysdig
Wednesday November 13, 2024 4:30pm - 5:05pm MST
Salt Palace | Level 1 | 155 B
In this session, we'll explore challenges faced in maintaining optimal performance for Container Network Interface (CNI) and Kubelet components in Kubernetes clusters. Based on recurring real-world scenarios, we will dive into troubleshooting and mitigations of issues such as IP address allocation delays, registry pull queries per second (QPS), disk throttling. These pose significant impacts on the performance, scalability and stability of Kubernetes clusters. Our discussion will revolve around practical strategies aimed at mitigating such challenges, leveraging multiple block storage volumes, adjusting instance types, tuning registryPullQPS settings, and exploring the benefits of prefix mode for faster IP address allocation. Additionally, we'll examine the role of warm IP pools, and the implications of WARM_ENI_TARGET settings on CNI performance, providing attendees with a comprehensive understanding on how to optimize CNI and Kubelet performance effectively.

Misadventures in Large Scale Cluster Performance - Shane Corbett, AWS & Dima Ilchenko, Lacework
Wednesday November 13, 2024 5:25pm - 6:00pm MST
Salt Palace | Level 1 | 155 B
Join us for our follow up to one of the highest rated talks of kubecon 2022 (73,000 pods a day, lessons from misadventures in multi-tenant). We are on a new misadventure, asking the question what if some of the most popular advice about Kubernetes was just...wrong? We spent over two years pouring through 800 page linux kernel performance books, tweaking obscure control plane settings, and developing detailed custom monitoring dashboards so you don’t have to! Join us as we take you through real world findings that took months of research to fully understand, and provide evidence that some of the things we were convinced were best practices, were the very things holding us back the most.
