按部署、授权与配额、域名配额、高可用边界、日志分析和旧版本兼容分类整理。所有回答均以产品实际实现为准，不使用未经依据的数字；价格信息请参阅授权定价页面。 Organized by deployment, licensing and quota, domain quota, HA scope, log analytics and legacy compatibility. Every answer reflects the real implementation and uses no unsupported numbers; for pricing, see the Pricing page.
01部署Deployment
FunCDN 采用什么部署方式？What deployment model does FunCDN use?
FunCDN 采用私有化自建部署。一套系统包括主控（API 服务和管理面板）、边缘节点、可选的回源中继，以及常驻在每台主机上的
cdn-agent。所有组件均原生运行在您自己的 Linux 服务器上，并由主控统一编排。FunCDN uses private, self-hosted deployment. A system includes the control plane (API service and web panel), edge nodes, an optional origin relay, and a cdn-agent resident on each host. All components run natively on your own Linux servers, orchestrated by the control plane.FunCDN 是否依赖公有云？Does FunCDN depend on public cloud?
不依赖。主控和节点均可运行在自有服务器或自有机房中，支持完全私有化部署。是否选用公有云主机由您决定，FunCDN 本身不绑定任何公有云厂商。No. Both the control plane and nodes can run on your own servers or datacenters, supporting fully self-hosted deployment. Whether to use public-cloud hosts is up to you — FunCDN itself is not tied to any cloud vendor.
02授权Licensing
全功能版是否已包含全部核心功能？三个版本如何划分？Does Full already include all core features, and how do the editions differ?
是。全功能版已开放全部 CDN 核心功能，并按节点数及 Zone（根域名）配额档位计费。增强版在此基础上增加一组高级功能与专家服务；定制版进一步提供定制研发和专项交付。页面级高可用只是高级功能之一。当前授权仅按版本以及节点 / Zone 配额划分；早期按 CDN、WAF 等单项功能开关授权的方式已经废弃。Yes. The Full edition includes every CDN core capability, priced by node and Zone (root-domain) quota tier. Enhanced adds a set of advanced capabilities and expert services on top; Custom further adds project-specific development and delivery. Page-level HA is just one of the advanced capabilities. Licensing is scoped only by edition plus node / Zone quota — the old per-feature switches (CDN, WAF and so on) are deprecated.
FunCDN 如何定价？How does FunCDN price its editions?
价格由授权节点数和授权站点数（按根域名 / Zone 计）共同决定。全功能版设有五档基础月费，价格为 ¥399–¥1,999/月；增强版按所选全功能版基础月费另加 ¥999/月；定制版根据需求范围评估定价。完整的五档价格、计费口径和实时计算器请查看授权定价页面；版本能力差异请查看功能对比页面。Price is set by licensed node count and licensed-site count (per root domain / Zone). Full has five base monthly tiers of ¥399–¥1,999/mo; Enhanced adds ¥999/mo on top of the chosen Full base; Custom is priced to scope. For all five tiers, the billing basis and a live calculator, see the Pricing page, and the feature comparison for how editions differ.
03域名配额Domain quota
Zone 配额如何计算？子域名是否额外占用配额？How is Zone quota calculated? Do subdomains use extra quota?
配额按 Zone（根域名）数量和节点数量计算。一个 Zone 对应一个根域名，该根域名下的子域名统一在同一 Zone 中管理，不会额外占用 Zone 配额。具体上限由授权文件中的节点配额和 Zone 配额决定，本页面不固定列出数值。Quota is counted by number of Zones (root domains) and nodes. A Zone maps to one root domain, and subdomains under that root domain are managed within the same Zone — they use no additional Zone quota. Exact limits come from the node and Zone quotas in your license file; this page states no fixed numbers.
04高可用High availability
哪些版本支持高可用？实际覆盖范围是什么？Which editions support HA, and what does it actually cover?
高可用规则仅面向增强版和定制版开放。全功能版可以看到功能入口，但调用管理接口时会返回 403，并提示升级版本。该功能只为页面导航请求提供页面级容灾：导航请求会先正常访问主地址；主地址请求失败后，浏览器依次探测预设的备用地址，并跳转至第一个可访问的地址；只有当所有备用地址均不可达时，才显示离线页。它不会对页面中的图片、脚本等所有子资源提供透明容灾。查看高可用工作原理 →HA rules are available only in Enhanced and Custom. The Full edition can see the entry, but calling the management API returns 403 with a prompt to upgrade. It provides page-level failover for page-navigation requests only: a navigation first hits the primary as usual; if that request fails, the browser probes the preset backups in turn and redirects to the first reachable address, showing an offline page only if every backup is unreachable. It does not provide transparent failover for all of a page's sub-resources such as images or scripts. See how HA works →
05日志分析Log analytics
使用日志分析是否必须部署 ClickHouse？Is ClickHouse required to use log analytics?
不是，而且是否部署 ClickHouse 与授权版本无关。访问、缓存和回源等日志分析能力依赖外置 ClickHouse，但 ClickHouse 属于可选组件。未接入时，相关分析页面将显示为空状态，内容加速、安全防护和证书等核心链路不受影响；边缘节点本身也不依赖 ClickHouse。No — and whether you deploy ClickHouse is independent of your edition. Access, cache and origin-pull analytics rely on an external ClickHouse, but ClickHouse is an optional component. Without it, the related analytics pages show an empty state, while the core paths — content delivery, security and certificates — are unaffected; the edge node itself has no ClickHouse dependency.
06旧版本兼容Legacy compatibility
旧版本名 standard、professional 和 enterprise 是否仍然兼容？Are the legacy edition names (standard, professional, enterprise) still supported?
兼容。历史版本名会映射到当前三个版本：standard 对应全功能版，professional 对应增强版，enterprise 对应定制版。无法识别的旧版本值会按保守策略降级为全功能版，不会获得高可用权限。映射完成后，配额和功能权限均以对应的当前版本为准。Yes. Legacy edition names map onto today's three editions: standard → Full, professional → Enhanced, enterprise → Custom. Unrecognized legacy values are conservatively downgraded to Full and are not granted HA. After mapping, quotas and feature permissions follow the corresponding current edition.
把 CDN 的控制权掌握在自己手中Keep full control of your CDN
按节点数和授权站点数（以根域名 Zone 计）透明计费，可根据实际部署规模选择合适的授权档位。Transparent pricing by node count and licensed-site count (counted per root-domain Zone) — choose the licensing tier that matches your deployment.
