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.

One Inventory to Rule Them All: Standardizing Multicluster Management - Corentin Debains, Google & Ryan Zhang, Microsoft

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

Salt Palace | Level 1 | 155 BC

Most Kubernetes users run more than one cluster, and some run hundreds or more. Crossing cluster boundaries has always been a challenge, because most Kubernetes APIs, tools, and operators are cluster-centric. In fact, there’s a remarkable lack of standard tools and patterns for multi-cluster. Over time users have found ways to stitch clusters together but the community has been asking for standardization.To share multi-cluster tools, Kubernetes sig-multicluster has introduced the “ClusterProfile” API, a critical building block for multi-cluster capabilities. This API provides a canonical way for multicluster controllers and users to iterate over clusters, and to install or manage multi-cluster features. In this talk, we will look at some of the problems inherent to multi-clustering, explain the concepts introduced by this new API and look at implementations and consumers of it.We dive into real life examples of patterns and usage, with products such as Kueue, ArgoCD, and Argo workflow.

What has Kubernetes got to do with a High Energy Physics experiment collecting one million physics events per second at a data rate of 5 TB/s? That is what we would like to show you! The ATLAS experiment at CERN filters one million complex collision signatures per second provided by the Large Hadron Collider in quasi real-time, using a mixture of custom electronics and a large computing farm (the Event Filter – EF – farm) consisting of up to 5000 commodity servers. In this talk, we will tell you how we are going to exploit Kubernetes to orchestrate the ATLAS EF computing farm. In particular, we will focus on the strategy and optimizations we put in place in order to start more than 25000 PODs over more than 2500 worker nodes in about 50 seconds. We will also show the impact of the Kubernetes Scheduler and Controller Manager QPS values on POD start and stop throughputs and we will report about how custom scheduler profiles allow us to schedule PODs at an average rate of about 500 Hz.

Per-Node Api-Server Proxy: Expand the Cluster's Scale and Stability - Weizhou Lan & Iceber Gu, DaoCloud

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

Salt Palace | Level 1 | 155 BC

For lots of CNCF projects, kinds of daemonsets simultaneously synchronize datas from the Api-server from each node. Especially in large-scale clusters, it creates significant pressure on the Api-server, burdens the network, even affects the stability of the cluster. Some projects have implemented optimization to address this. For instance, Cilium aggregates endpoint information into the CRD CiliumEndpointSlice before distributing it to its daemonset. However, many projects have not yet adopted such data aggregation optimizations and Currently, there is still no project to help improve the communication between all components and the Api-server. ClusterPedia supports to launch per-node Api-server proxies to serve all local pods, and utilize eBPF to resolve the API server's clusterIP to the local proxy, which transparently implements API server access redirection on demand. In large-scale clusters, this can significantly improve the stability of all cluster's services.

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

Salt Palace | Level 1 | 155 BC

In the dynamic world of Kubernetes, efficient resource management is crucial for optimizing performance and costs. Traditionally, managing resource requests and limits in Kubernetes has focused on individual containers within a pod. While this approach offers granular control, it can become cumbersome and error-prone, particularly for complex applications with multiple containers. Join us as we'll examine the challenges and scalability limitations posed by container resource micromanagement resource allocation. To address this issue, the pod-level feature specification is introduced. In this session, we'll delve into the transition towards pod-level resource specifications, providing an intuitive method for defining resource requests and limits at the pod level, in conjunction with the existing container-level settings. This innovative approach offers enhanced flexibility and optimized resource utilization for a variety of workloads, including those with init containers and sidecars.

Strategies for Mitigating Performance Interference in Cloud-Native Systems - Jonathan Perry, Startup

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

Salt Palace | Level 1 | 155 BC

In cloud-native environments, application performance often degrades due to contention over shared resources such as CPU caches and memory bandwidth. Current container technologies lack mechanisms to isolate these resources, which compels operators to maintain low utilization by scaling out their deployments. This session explores strategies used by hyperscalers like Google, Microsoft, Facebook, and Alibaba to mitigate such performance interference. We will review their published methodologies, extracting key principles that could guide the development of a Kubernetes-native performance isolator. Participants will gain insights into the design trade-offs and operational impacts of these tools. Additionally, we will discuss integration strategies for deploying such isolators in existing Kubernetes environments, aiming to optimize resource utilization while preserving application performance.

The Key Value of Etcd Over Custom Resources: Scalability - Jef Spaleta, Isovalent at Cisco

Friday November 15, 2024 2:55pm - 3:30pm MST

Salt Palace | Level 1 | 155 BC

Cilium defaults to using Kubernetes Custom Resources to hold Cilium specific internal state, however when the cluster is large enough, the Kubernetes API becomes a bottleneck on performance. To scale a cluster to hundreds of nodes, Cilium can be configured to use a dedicated external etcd instance. This talk will discuss the details of what the external etcd looks like from an operator perspective, and explore why Cilium uses an external etcd for enhanced scalability. It will cover how to manage a cluster by bypassing the Kubernetes API and interacting only with the cluster's etcd key-value store - and also why it might be a bad idea. Get a taste of what's possible by bypassing the Kubernetes API and interacting with the etcd API directly, and learn why Cilium has an option to use a dedicated etcd deployment, not shared by the Kubernetes API, for holding Cilium state and the scalability benefits it can bring to your cluster.

Service Profiling Based Management and Scheduling in K8s - Jia Deng, Cong Xu & Mingmeng Luo, Bytedance

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

Salt Palace | Level 1 | 155 BC

We present an open-source solution for the efficient management of resources and scheduling strategies in K8s. Our solution constructs workload-specific resource profiles based on their historical utilization patterns. This approach ensures that workloads receive adequate resources while optimizing overall resource utilization. To accomplish this objective, we employ a custom resource Service Profiling Description (SPD), facilitating a direct correlation between workloads and their resource usages, such as deployments and stateful sets etc. Resource utilization metrics, including CPU, disk I/O, and network I/O, are meticulously collected and aggregated. These usage indicators play a pivotal role in informing the scheduler's decisions regarding workloads allocation. This solution has been deployed within large-scale K8s clusters, addressing diverse workload demands, ranging from those requiring dedicated NUMA nodes to those capable of resource sharing among themselves.
