360 Zhihui Cloud is an enterprise open service platform that aims to "aggregate data value and empower an intelligent future," leveraging 360's extensive product and technology resources to deliver platform services to customers.
This comprehensive guide explains how to use Go's built‑in pprof tool to profile CPU, memory, and goroutine behavior, covering integration methods, command‑line analysis, visualization techniques, and step‑by‑step solutions for common performance bottlenecks in production Go services.
Facing the challenge of moving 15 billion image files from Cassandra to S3, we iteratively redesigned the migration pipeline—from a single‑process approach to multi‑process, queue‑driven, and multi‑cluster deployments—reducing the projected 120‑day effort to just 40 days while ensuring reliability and performance.
This article explains what a Distributed File System (DFS) is, outlines key evaluation criteria such as reliability, availability, performance, scalability, and then compares HDD and SSD performance, investigates whether DFS can surpass local NVMe in large‑IO workloads, and discusses user‑side, cluster‑level, and cache‑level performance assessment methods.
This article details the design, technology choices, functional modules, core implementation, performance optimizations, and future roadmap of Ops‑Nexus, an AI‑driven intelligent operations platform that streamlines alarm analysis, log processing, and host health checks for large‑scale monitoring environments.
This article explains Go's sync.WaitGroup concurrency primitive, covering its core methods, a classic example, key characteristics, common pitfalls, and best‑practice rules to reliably wait for multiple goroutines to finish before proceeding.
This article examines how to centrally manage GPU resources across heterogeneous Kubernetes clusters using namespace‑based RBAC isolation, virtual control‑plane solutions like vcluster, and multi‑cluster tools such as Karmada, comparing their architectures, use cases, advantages, and limitations to guide enterprise‑level deployment decisions.
This step‑by‑step guide walks you through initializing a Kubernetes controller project with kubebuilder, writing the Reconcile logic, debugging and performance monitoring, building and pushing Docker images, and deploying the controller using Helm charts, while also covering metrics collection, RBAC configuration, and best practices for cloud‑native workloads.
This article compares two micro‑frontend frameworks (Qiankun and Umi Micro) and an iframe‑based solution, detailing their principles, feature comparisons, pros and cons, integration costs, typical scenarios, common pitfalls, and improvement plans to help developers select the most suitable approach for multi‑platform product integration.
This article explains how Erasure Coding (EC) improves data reliability and dramatically reduces storage overhead in Ozone by leveraging hot‑cold data characteristics, intelligent tiering, dynamic EC ratios, and repair throttling, while also discussing performance trade‑offs and limitations.
This article examines the factors affecting media transcoding duration, explains why decoding dominates processing time, and presents multi‑threaded FFmpeg techniques and a cluster‑based architecture that split video into TS segments to dramatically reduce overall transcoding latency.
