This article walks through Intel's high‑density scalable load balancer (HDSLB), detailing its layered software architecture, advanced elephant‑flow handling, fast/slow‑path separation, packet‑forwarding optimizations, and provides a deep code analysis of its configuration, initialization, and data‑plane job execution.
Intel’s HDSLB series introduces a high‑density, scalable L4 load balancer that leverages Intel Xeon CPU instructions and E810 NIC acceleration to deliver multi‑core linear performance, superior throughput, and robust features for cloud and edge networking, outperforming traditional LB solutions.
An accessible Chinese-to-English guide demystifies cloud native by likening it to a city, outlines its definition, core traits, evolution through three philosophical questions, practical “Wang’s Four Rules,” development stages from cloud‑hosted VMs to containers and serverless, and discusses applicability in private and traditional enterprises.
This article explains cloud computing in plain language, covering its definition, the evolution of computation, public vs. private cloud models, the nine key advantages of public cloud, its value as digital‑age infrastructure, and the roadmap toward making cloud services as ubiquitous and reliable as electricity.
This article provides a comprehensive analysis of OpenStack Octavia’s LBaaS implementation, covering its core components such as Amphora, VIP management, network topology, listener and pool creation, health monitoring, SSL communication, and the automated failover process that ensures high‑availability load balancing for cloud environments.
HAProxy is an open‑source L4/L7 load balancer offering reverse‑proxy, session persistence, diverse balancing algorithms, ACL‑based routing, health checks, and a web UI; the guide details its high‑performance architecture, high‑availability deployment with Keepalived, configuration examples, and extensive kernel and system tuning for massive traffic.
This article provides a comprehensive guide to Linux Virtual Server (LVS) load balancing, covering its architecture, core concepts, software modules, NAT/TUN/DR modes, scheduling algorithms, ipvsadm command usage, and step‑by‑step deployment of LVS‑NAT with Keepalived for both TCP and UDP scenarios.
This article explains the VRRP protocol’s core concepts, state machine, election process, and multi‑master HA mode, provides step‑by‑step Linux router configuration examples—including group creation, priority, interface tracking, preempt mode, timers, and learning—plus an overview of Keepalived’s architecture and split‑brain mitigation strategies.
This article explains how modern data‑center virtualization is shifting from one‑to‑many to many‑to‑one VM models, then walks through the virtio and vhost‑net architectures, their kernel and user‑space components, and provides a step‑by‑step guide to set up a nested KVM environment with OVS for external network access.
This article explains the virtio framework for para‑virtualized hypervisors, comparing full and para‑virtualization, detailing the architecture, buffer model, core API, driver examples, and future directions, providing a comprehensive overview of Linux I/O virtualization.
