ARM-Wrestling: Overcoming CPU Migration Challenges to Reduce Costs - Laurent Bernaille & Eric Mountain, Datadog

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

Salt Palace | Level 1 | 155 BC

When you have a significant cloud footprint, you always look for performance improvements and cost reductions. So when ARM instances became commonly available on one of our providers, seemingly providing great performance at a lower cost, we had to take a closer look! In this talk, we will first describe the steps we took to make our clusters ARM-ready and a few interesting issues we encountered during our initial tests: from performance regressions due to compiler behaviors to subtle memory corruption bugs. We will then discuss new challenges, in particular how to achieve load-balancing and auto-scaling when running workloads on a mix of CPUs with different performances, and share our results. If migrating real workloads to ARM proved challenging, it was worth the effort and we now run more than 50% of our workloads on ARM.

Automated Multi-Cloud, Multi-Flavor Kubernetes Cluster Upgrades Using Operators - Ziyuan Chen, Databricks

Wednesday November 13, 2024 12:10pm - 12:45pm MST

Salt Palace | Level 1 | 155 BC

Databricks manages over a thousand k8s clusters across three major cloud providers which run critical workloads in cloud regions around the world. This talk describes the system we built to upgrade nodes’ operating system, k8s version, and other configs monthly, supporting EKS, AKS, GKE, and self-managed k8s. Our system is built on k8s operators and performs zero-downtime blue-green rolling updates, respects contracts with services with features like PDBs, maintenance windows, deferred node draining, and custom workload handling plugins. It enables easy rollbacks, has good observability, and incurs minimal human operational cost. This has allowed us to patch vulnerabilities and release infrastructure changes quickly and reliably across the fleet. We will also share our lessons learned on building several operators that work together using the controller-runtime framework, designing the declarative interfaces between them, and achieving consistent behavior across three clouds.

Does My K8s Application Need CPR? Performance Evaluation of a Multi-Cluster Workload Management App - Braulio Dumba & Ezra Silvera, IBM

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

Salt Palace | Level 1 | 155 BC

KubeStellar (KS) is an open-source Kubernetes multi-cluster workload configuration management system that can be used to manage AI workloads in multi-cluster environments. Hence, understanding KS performance is crucial especially when managing resource intensive AI workloads. In this talk, we will present our experience in analyzing the performance metrics of KS across several dimensions of scalability (e.g., number of bindingPolicies, workload description spaces and number of managed remote clusters) and challenges that arise when conducting performance experiments in a multi-cluster environment. Our insights will demonstrate the utility of benchmarking the performance of a multi-cluster Kubernetes workload management application. Additionally, in this talk, we will demonstrate the usefulness of using several opensource tools such as clusterloader2, kube-burner & kwok to evaluate the performance of multi-cluster Kubernetes management applications.

Global Payments: Setting New Standards for Reliability in Cloud Native Multi-Region Applications - Trey Caliva, Global Payments

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

Salt Palace | Level 1 | 155 BC

As a multinational FinTech provider, processing over 32 billion card transactions for 816 million accounts, Global Payments requires globally available architectures with quick disaster recovery while maintaining subsecond latencies. In addition, these workloads require strict adherence to compliance standards. This session will explore the high-level architectural decisions implemented in a cloud-native redesign and cloud migration of a mission critical legacy .NET application. Key cloud native tools leveraged include Kubernetes on GCP, and the use of CockroachDB as a cloud native database solution. We will explore how leveraging these cloud native technologies achieved extreme fault tolerance in a multi-region deployment, setting new standards for performance and reliability.

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 BC

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 BC

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.
