"SR-IOV Networking in Kubernetes"
"SR-IOV Networking in Kubernetes" is the definitive guide for infrastructure engineers, cloud architects, and advanced practitioners seeking to unlock high-performance networking within Kubernetes environments. Emerging at the intersection of container orchestration and cutting-edge hardware-assisted virtualization, this comprehensive book demystifies Single Root I/O Virtualization (SR-IOV) in the context of cloud-native workloads. Readers are led from fundamental architecture—covering PCIe hierarchy, virtualization technologies, and kernel interfaces—to advanced use cases motivating the adoption of SR-IOV for low-latency and high-bandwidth applications.
The book provides expert, step-by-step coverage of the hardware, system, and software preparations essential for SR-IOV deployment, including BIOS and firmware configuration, NUMA-aware networking, and secure device assignment. It delves into the integration of SR-IOV with Kubernetes via device plugins and CNI frameworks, demystifying configurations, multi-networking with Multus, and network interface provisioning. Meticulously detailed workflow examples and deployment patterns illuminate best practices for both stateful and stateless workloads, fine-grained scheduling, quality of service, and day-2 operations such as scaling, upgrades, and migration.
Security, observability, and future-facing innovation are at the heart of this resource. In addition to robust monitoring, diagnostics, and troubleshooting methodologies, the book explores layered security measures, including RBAC, pod security policies, kernel hardening, and service mesh integration for zero-trust models. The final sections map the evolving ecosystem—examining NFV, DPDK, 5G edge solutions, and the advent of PCIe Gen5—while providing actionable guidance on standardization, automation, and community best practices. "SR-IOV Networking in Kubernetes" is an authoritative, indispensable reference for building performant, secure, and future-proof Kubernetes platforms.
