每个场景都是现有能力的组合，按实际业务需要挑就行。 Every scenario here is a combination of capabilities FunCDN already has; pick whichever ones fit your workload.
场景之间可以按需要组合，每张卡片末尾的链接指向对应能力的详细说明。The scenarios can be combined as needed, and the link at the end of each card leads to the capability behind it.
内容分发跑在自己的服务器和带宽上。主控和节点都在自有网络里，配置和日志不用出内网。Content delivery runs on your own servers and bandwidth. The control plane and the nodes both sit inside your network, so configuration and logs never have to leave it.
了解部署架构 →Deployment architecture →在不同地区部署边缘节点，用户就近访问。配合缓存策略、内存和磁盘两级缓存以及 HTTP/2，改善静态和动态站点的访问体验。Put edge nodes in different regions so users reach a nearby one. Cache rules, the memory and disk cache tiers and HTTP/2 together improve the browsing experience on both static and dynamic sites.
了解缓存与接入能力 →Caching & delivery →源站池做负载均衡，同时用主动健康检查发现故障，再自动切到可用的源站。也可以部署回源中继，当作备用的回源链路，进一步提高回源可靠性。The origin pool load-balances traffic and uses active health checks to detect failures, then switches automatically to a healthy origin. An origin relay can also be deployed as a backup path to the origin, which makes origin pull more reliable.
了解源站池与健康检查 →Origin pools & health checks →WAF、IP 访问控制、访问限速、CC 防护和 JS Challenge 都在边缘统一配置，每个站点可以单独组合，攻击流量尽量在边缘就处理掉。WAF, IP access control, rate limiting, CC defense and JS Challenge are all configured at the edge from one place, and each site combines them differently, so as much attack traffic as possible is stopped at the edge.
了解安全策略能力 →Security policy →关键站点可以挂高可用规则。主地址请求失败后，浏览器按顺序探测预设的备用地址，跳到第一个能通的；备用地址全部不可达，才显示离线页面。仅增强版和定制版可用。Critical sites can have HA rules attached. After a request to the primary fails, the browser probes the preset backup addresses in order and redirects to the first reachable one. The offline page appears only if none of the backups are reachable. Available in the Enhanced and Custom editions only.
了解高可用工作原理 →How HA works →证书、配置、日志和操作审计数据都留在自有环境里。备份恢复配合角色权限，能满足运维数据不出内网的部署要求。Certificates, config, logs and audit records all stay inside your own environment. Backup and restore plus role-based access cover the requirement that operational data never leaves your network.
了解运维与日志分析能力 →Operations & log analytics →按节点数和授权站点数（以根域名 Zone 计）透明计费。选哪一档看实际部署规模，选哪个版本看您需要哪些高级功能与服务。Transparent pricing, based on licensed node count and licensed sites counted per root-domain Zone. The tier follows your deployment size; the edition follows which advanced capabilities and services you need.
