Comprehensive Overview of Desktop Cloud Solutions, Architecture, and Industry Landscape

Desktop cloud (desktop virtualization) integrates front‑end and back‑end hardware and software, combining server, desktop, and storage virtualization to deliver operating system interfaces as images to client devices, offering secure data protection, efficient management, and flexible user access.

According to deployment methods, desktop cloud can be private, public, or hybrid. It is a virtualization‑based solution that can customize standardized system templates for different business scenarios, using remote desktop protocols, virtual disk I/O, and address mapping to present templates locally.

Common architectures include VDI (Virtual Desktop Infrastructure) and IDV (Intelligent Desktop Virtualization), with VDI emphasizing centralized computing and management, while IDV offers centralized storage and distributed computing for better performance and peripheral compatibility.

The industry consists of upstream hardware/software providers (thin clients, servers, OS, middleware), mid‑stream desktop‑cloud service providers, and downstream enterprise users in sectors such as government, telecom, education, medical, and finance.

CPU hardware is a core component, categorized into high‑performance (large), desktop‑level (medium), and mobile/embedded (small) CPUs. Domestic manufacturers have made progress in high‑performance and desktop CPUs, though gaps remain compared with international vendors.

Middleware and operating systems are also critical; domestic middleware vendors are gradually replacing foreign products, and Chinese desktop/server OSes (e.g., Kylin, UnionTech, Red Flag) are achieving independent development.

End‑to‑end desktop‑cloud solution providers (e.g., Shengteng Information, Huawei, Sangfor, Dell) offer integrated hardware and software platforms supporting Windows, Linux, Kylin, and UOS cloud desktops.

Application scenarios include government (secure isolated networks), telecom (virtual desktop pools), education (high‑speed campus networks), medical (centralized management with disaster recovery), and finance (strict data isolation).

Desktop cloud relies on protocols such as RDP, ICA/HDX, PCoIP, and SPICE, providing high‑resolution display, multimedia streaming, multi‑monitor support, USB redirection, and driver mapping. vGPU solutions enable high‑performance graphics for 3D, video encoding, and AI workloads, reducing CPU load and improving user experience.

The competitive landscape features three groups: cloud‑computing companies (Alibaba Cloud, JD Cloud, Tencent Cloud), traditional IT vendors (Huawei, Sangfor), and desktop‑cloud startups (e.g., Bintec). Each leverages its strengths in cloud services, legacy IT expertise, or vertical specialization.

Overall, desktop cloud represents a system‑engineered approach combining terminals, networks, servers, and software, offering cost, energy, and management advantages that drive its adoption across multiple sectors.
