This article examines Kubernetes networking by defining underlay and overlay models, describing how underlay networks like flannel host‑gw and Calico BGP operate, explaining IPVLAN/MACVLAN virtualization, and reviewing common tunnel protocols such as VxLAN and IPIP used by various CNI plugins.
This article explains the motivations behind Kubernetes multi‑cluster deployments, outlines common use cases such as isolation and high‑availability, and analyzes core management elements including deployment models, control‑plane architectures, network connectivity, service discovery, cross‑cluster scheduling, application model extensions, and treating clusters as resources.
This article explains Kubernetes' networking architecture by detailing the underlay and overlay models, comparing layer‑2 and layer‑3 designs, and reviewing common CNI implementations such as Flannel, Calico, Multus, and DANM, along with their underlying technologies.
This article explains Kubernetes networking models, detailing the underlay network infrastructure, overlay techniques, and common CNI implementations such as Flannel, Calico, IPVLAN, and VxLAN, while comparing their architectures, protocols, and configuration considerations.
This article provides a comprehensive overview of Kubernetes networking by explaining the concepts of underlay and overlay network models, describing their implementations such as flannel host‑gw, Calico BGP, IPVLAN/MACVLAN, and tunneling technologies like VxLAN and IPIP, and offering practical references for each approach.
This article provides a comprehensive overview of Kubernetes networking, explaining the concepts of underlay and overlay network models, their implementations with Flannel, Calico, IPVLAN, MACVLAN, Multus, DANM, and common tunneling protocols such as VxLAN, IPIP, and GRE, while highlighting practical configuration notes and architectural differences.
This article provides a comprehensive overview of Kubernetes, covering its core functions, main components, service‑discovery mechanisms, pod‑level resource sharing, common CNI plugins, multi‑layer load balancing, isolation dimensions, and the fundamental network model principles that guide large‑scale container deployments.
This article explains Kubernetes' network model, covering container‑to‑container, pod‑to‑pod, pod‑to‑service, and external traffic flows, while detailing network namespaces, veth pairs, Linux bridges, iptables/IPVS load‑balancing, and cloud‑native solutions like LoadBalancer and Ingress controllers.
This article provides a comprehensive overview of Kubernetes architecture, covering container operations, core components, multi‑center deployment models, service discovery methods, pod resource sharing, CNI plugins, load‑balancing layers, isolation dimensions, network principles, and IP address classifications.
The article traces Redis’s shift from its original single‑threaded reactor model to the I/O‑threaded architecture introduced in version 6, explaining how atomic operations and round‑robin client distribution let separate threads handle network I/O and parsing while the main thread executes commands, yielding roughly a two‑fold throughput boost but retaining a single‑threaded command core and incurring brief CPU spikes from busy‑wait synchronization.
This article explains how Linux hosts use TAP/TUN to simulate virtual switches and layer‑3 devices, detailing four common single‑host virtual network models—NAT, routing, bridge, and isolation—and how they enable communication between virtual machines and external networks.
