This article explains how Alibaba Cloud Container Service for Kubernetes (ACK) has upgraded its storage monitoring dashboards to provide detailed visibility into local, PVC, and cloud‑based volumes, enabling users to detect IO bottlenecks, track real‑time read/write performance, and improve overall container reliability.
This article explains Docker's OverlayFS/Overlay2 storage driver, detailing its layered image architecture, union‑mount mechanics, read/write behavior, metadata organization, and the roles of image, layer, and init layers within the container filesystem.
This article explains how container images are stored on disk, details the evolution of storage drivers, and guides readers through configuring the storage.conf file for tools like Podman, including driver selection, graphroot, and advanced options such as additional image stores and UID/GID remapping.
Understanding the data path in Kubernetes systems reveals performance bottlenecks and guides the selection among private‑cloud storage, container‑native storage software, and software‑defined storage to achieve scalable, low‑latency, high‑performance container workloads.
This article examines Alibaba Cloud's cloud‑native storage innovations, including the DADI block‑layer image accelerator, high‑density ESSD cloud disks, and the CNFS container network file system, detailing their architectures, performance benefits, and large‑scale deployment results.
This article explains the concept of union file systems, compares implementations such as UnionFS, aufs, OverlayFS, ZFS and Btrfs, and demonstrates how Docker leverages OverlayFS with copy‑on‑write layers to create lightweight, fast‑starting containers.
This tutorial explains the lifecycle and use‑cases of Kubernetes emptyDir and hostPath volumes, shows how to configure them in pod specs, demonstrates a sidecar pattern for temporary data sharing, and provides complete YAML and kubectl commands for creation, inspection, and troubleshooting.
This article explains why storing data in a container layer is problematic and details Docker's three persistent storage options—volumes, bind mounts, and tmpfs—along with their usage commands, scenarios, and advanced features such as bind propagation, SELinux labels, and volume drivers.
The Beijing cloud‑native technology salon on April 20 showcased expert talks on Kube‑OVN networking, Oracle Linux Ksplice hot‑patching, 360’s Wayne multi‑cluster platform, YRCloudFile container storage, and CI/CD strategies, highlighting practical advances and open‑source projects for modern cloud environments.
This article explains how Portworx implements container-defined storage with a distributed metadata‑driven block layer, detailing its architecture, control‑plane and data‑plane operations, lifecycle management, integration with orchestration tools, and real‑world scenarios such as big‑data, CMS, and database workloads.
The article explains how container technology is reshaping data‑center storage through Container‑Defined Storage (CDS), discusses the limitations of traditional storage architectures, highlights Portworx’s approach, and outlines the requirements for service‑oriented, distributed, and hyper‑converged storage in modern cloud‑native environments.
This article explains the concepts, usage, and performance characteristics of AUFS, a Union File System used in Linux and Docker, providing examples of mounting, branch permissions, whiteout handling, and configuration options, while discussing its role in container image layering.
