Strategies for Mitigating Performance Interference in Cloud-Native Systems
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 and Alibaba Cloud 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.
Understanding How OpenTelemetry Network Uses eBPF for Network Observability
The recent advancements in eBPF tooling, including the enhanced eBPF runtime embedded in the Linux kernel, the BPF Compiler Collection (BCC) for efficient kernel tracing, and the LLVM Compiler for converting C code to eBPF programs, have made it easier to provide always-on network visibility. OpenTelemetry Network leverages these foundational tools to provide out-of-the-box network observability for modern infrastructures.
In this talk, we'll explore the architecture of the OTel Network, focusing on its key components: the kernel collector, kubernetes collector, cloud collector, and reducer which together enable collecting, ingesting, aggregating, enriching, and exporting telemetry data collected from various sources. We'll show an end-to-end setup to demonstrate the use of these agents and reducer component to send data to the OTel collector. This session aims to equip end-users and contributors with the necessary infomation to get started with the OpenTelemetry Network project.
