OrangeFS: A Cloud‑Native Multi‑Protocol Distributed Data Lake Storage System

OrangeFS is Didi’s cloud‑native, multi‑protocol distributed data‑lake storage system that unifies POSIX, S3 and HDFS access on a single logical hierarchy, integrates with Kubernetes via a CSI plugin, supports on‑premise and public‑cloud backends, provides multi‑tenant isolation, and dramatically improves elasticity, utilization and latency for petabyte‑scale workloads such as ride‑hailing logs, machine‑learning training, finance and analytics.

Observability: Concepts, Challenges, and Didi’s Implementation

The article explains observability as the ability to infer any system state from external data, contrasts it with traditional monitoring, outlines challenges of high‑dimensional, high‑cardinality data and storage costs, and describes Didi’s hybrid MTL architecture that separates low‑ and high‑cardinality logs and metrics while linking them via TraceIDs to provide detailed, cost‑effective insight and streamlined debugging.

Service Management and Resource Abstraction in Cloud‑Native Environments Using OAM and KubeVela

To tackle the exploding number of microservices and heterogeneous infrastructure in cloud‑native enterprises, the article proposes a unified service‑and‑resource abstraction built on the Open Application Model and its implementation KubeVela, enabling declarative application definitions, cost attribution, automated lifecycle management, and cross‑region efficiency through component marketplaces, an application center, an operations platform, and a site‑building center.

Data Stability Construction and Fault Governance Practices at Didi Customer Service

Didi’s multi‑year data‑stability program for its customer‑service platform progressed through fault‑centered engineering, business‑aligned cross‑team work, and capability normalization, instituting pre‑, mid‑ and post‑fault safeguards, clear ownership, automated alerts and repair tools, which cut fault count by 42 % and more than doubled mean‑time‑to‑repair while boosting team communication and satisfaction.
