This article explains the design and implementation of Ctrip's Data Replication Center (DRC), a MySQL‑based high‑availability system that solves cross‑region data loop, progress tracking, concurrency, DDL handling, and conflict resolution to achieve low‑latency, reliable data replication for global travel services.
This article explores the complexities of cross‑region access control in cloud architectures, detailing latency, identity consistency, and policy uniformity challenges, and presents zero‑trust designs, distributed identity storage, multi‑layer encryption, edge policy execution, and monitoring strategies to achieve secure, high‑performance global access.
This article explains how Alibaba Cloud's SLS StoreView feature enables seamless, real‑time cross‑region and cross‑project log queries, replacing complex ETL pipelines with virtual logstores and offering powerful SPL‑based data processing, visibility control, and schema alignment for efficient cloud‑native observability.
This guide explains how Alibaba Cloud's SLS StoreView feature lets you combine logstores from multiple regions and projects into a virtual logstore, enabling real‑time cross‑domain queries, row‑level visibility control, schema alignment, and SPL‑based data processing without costly ETL pipelines.
This article explains how Alibaba Cloud's SLS StoreView feature creates virtual logstores that combine data from multiple projects and regions, allowing cross‑project queries, data isolation, enrichment, and unified analysis without costly data replication.
This article details JD Retail’s large‑scale HDFS deployment, describing how cross‑region storage challenges were solved with a full‑copy topology, asynchronous block replication, flow‑control mechanisms, and a tiered storage strategy that automatically moves hot, warm, and cold data among SSD, HDD, and high‑density HDD nodes to improve performance and cut costs.
This article presents JD's large‑scale big‑data platform, detailing its overall architecture, the challenges of cross‑region storage, the design of a unified cross‑domain data synchronization mechanism, and the implementation of tiered storage to improve performance, cost efficiency, and data reliability across multi‑datacenter clusters.
This article examines the challenges of cross‑region distributed consistency, reviews industry solutions such as direct deployment, learner roles, and partitioned services, and introduces Alibaba’s log‑mirroring decoupled architecture, evaluating trade‑offs in latency, scalability, availability, and consistency for global systems.
This article analyzes the evolution of high‑availability deployment—from cold backup to cross‑region multi‑active—explaining the trade‑offs of each solution, the challenges of stateful services, and real‑world architectures used by companies like Alibaba and Eleme.
This guide explains CloudEndure’s features and walks through a step‑by‑step example of configuring AWS cross‑region disaster recovery, covering initial project setup, data replication, test and recovery mode switching, and the failback process, while highlighting networking and security considerations.
