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.

Supercharge Your Kubernetes Autoscaling with Custom Metrics - Vamshi Krishna Samudrala & Sravan Akinapally, American Airlines

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

Salt Palace | Level 1 | 155 BC

Out-of-the-box, Kubernetes provides native horizontal scaling capabilities driven by conventional resource consumption signals like CPU and memory utilization. However, in the real world, numerous applications demand dynamic scaling orchestrated by custom business telemetry such as queue depths, throughput volumes, or other domain-specific indicators. This session will unravel the secrets of extending Kubernetes' Horizontal Pod Autoscaler (HPA) to leverage custom metrics as scaling triggers, unlocking unprecedented scaling autonomy. Attendees will witness live demos showcasing: Deploying a custom metrics provider to expose application-centric metrics to the Kubernetes control plane Configuring the HPA to consume these custom metrics for intelligent scaling decisions A sample application dynamically scaling based on a custom metric like queue length or requests per second Best practices for crafting bespoke scaling policies tailored to custom metrics.

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.

The Node Tetris Rabbit Hole: Why Your Binpacking Might Be Underperforming - Hannah Taub, Adobe Inc.

Friday November 15, 2024 4:00pm - 4:35pm MST

Salt Palace | Level 1 | 155 BC

Have you ever looked at your Kubernetes cluster and thought “I have a perfectly good autoscaler! Why are all my nodes at less than 50% capacity?” When a team moves to the scale of hundreds of clusters with thousands of nodes, efficient binpacking changes from a side task to a financial necessity. From inefficient client apps to long-buried cluster configs, follow the Adobe Ethos team as they track down leads on what’s causing cluster underutilization and how to fix it. You will also learn some tips for designing your clusters to avoid these issues in the first place.

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.
