Focused on system technology, sharing cutting‑edge developments, innovation and practice, and analysis of industry tech hotspots.
This article explains the principles behind Google’s sanitizer tools, especially AddressSanitizer, covering symbol interposition, the interceptor mechanism, and how these techniques replace libc functions to reliably locate memory and thread errors in C++ applications on Linux.
Sonic‑CPP, an open‑source C++ JSON library co‑developed by ByteDance’s STE and Service Framework teams, leverages SIMD vectorization, optimized memory layout, on‑demand parsing, and a compact DOM design to achieve up to 2.5× faster parsing than RapidJSON and competitive serialization performance, with extensive benchmark results and production‑grade usage.
This article explains the design of Virtio-fs, its architecture and high‑availability features, and details the crash‑recovery mechanism—including crash models, state preservation, supervisor coordination, request idempotence, downtime optimization, and hot upgrade/migration—implemented by ByteDance's STE team for secure container workloads.
This interview reveals how ByteDance’s STE team, a youthful group of Linux kernel engineers, identified and solved memory‑management redundancy, contributed the HVO and VDUSE projects to the open‑source community, and leveraged these advances to boost cloud‑native performance and reliability across the company.
This article reviews ByteDance's STE team's breakthrough that reduces KVM hot‑upgrade downtime from 1000 ms to 160 ms by transparently supporting PCI passthrough devices, detailing the underlying challenges, three key kernel/hypervisor improvements, proof‑of‑concept results, and their impact on cloud IaaS operations.
This article introduces the 2022 China Cloud Computing Infrastructure Developer Conference, highlights Zhang Jiachen's talk on the FUSE cache consistency model, explains the performance‑consistency trade‑off, and outlines optimization strategies and practical case studies for improving FUSE‑based storage solutions.
Using eBPF to bypass traditional bridge, netfilter, and routing steps, this article demonstrates how container network packet forwarding can be accelerated, reducing receive and transmit latency by around 40‑82%, with detailed perf‑ftrace analysis, code examples, and performance comparisons of three forwarding modes.
veLinux, an open‑source Linux distribution from Volcano Engine, delivers a stable, high‑performance, and secure operating system for cloud workloads on both x86 and ARM, offering multiple editions, deep kernel optimizations, fast boot, and extensive security features tailored for modern cloud‑native environments.
