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.
The article presents a fast/slow dual‑queue isolation and water‑level rate‑limiting design for the Ozone S3 gateway, detailing separate thread pools, async handling, bucket‑level throttling, and comprehensive metrics that together improve service stability and throughput under mixed workloads.
The article explains PD (Prefill‑Decode) disaggregation, an architecture that separates the compute‑bound Prefill stage from the memory‑bound Decode stage onto different GPU pools, eliminating interference, enabling independent scaling, leveraging hardware specialization, and delivering up to 85% lower tail latency for large language model inference.
The article analyzes why Nova VM port attach and detach operations can take 70‑90 seconds due to full‑cache refresh and coarse locks, proposes incremental cache updates and fine‑grained port locks, and shows benchmark results that cut attach time to 10‑17 s and detach time to about 7 s while eliminating lock contention and consistency errors.
The article details the design and implementation of VPC NAT gateway v2.0, explaining how new control‑plane fields, rule‑generation changes, and forwarding‑plane enhancements allow a single configuration to connect entire source VPCs to target VPCs, reducing complexity and operational cost.
PostgreSQL’s extensible architecture lets it evolve from a relational DB into a true multi‑model system supporting graphs, vectors, full‑text, time‑series, GIS and key‑value data, with detailed architecture explanations, practical code demos, cross‑model queries, extension selection, and production‑grade best‑practice tips.
This article explains PostgreSQL's native full‑text search, its core concepts of tsvector and tsquery, demonstrates how to use built‑in functions and operators, compares built‑in, zhparser, and pg_search extensions for Chinese tokenization, and provides best‑practice tips for indexing, triggers, and performance optimization.
This article explains how to integrate Ceph's erasure‑coded RBD pools with OpenStack, covering the design principles, storage pool layout, performance trade‑offs, and step‑by‑step configuration for Nova and Cinder to achieve higher storage utilization while maintaining high availability.
This article provides a comprehensive technical overview of SIP signaling, SDP negotiation, RTP/RTCP media transport, and the Binary Floor Control Protocol (BFCP), including their interactions, message flows, deployment models, and practical screen‑sharing implementations for video‑conference systems.
This article examines the limitations of traditional Kafka in large‑scale deployments and presents AutoMQ’s cloud‑native redesign—detailing its stateless architecture, storage separation, automatic scaling, read/write isolation, performance benchmarks, and real‑world migration case studies that demonstrate reduced latency, higher throughput, and lower resource costs.
This article explains how to design and implement hardware‑offloaded, IP‑ and port‑granular traffic shaping using Open vSwitch, OpenFlow meters, Mellanox HQoS, and DPDK, covering software limits, meter hierarchy, flow‑meter association, deletion workflows, RCU handling, and same‑host traffic considerations.
