🚀 The "10-Minute" Deployment Strategy | "10分钟"极速部署方案¶

This guide provides a streamlined, 4-step process to deploy your AI application globally, balancing cost, performance, and security. 本指南提供了一套精简的4步流程，帮助你实现AI应用的全球化部署，兼顾成本、性能与安全性。

📋 Overview | 方案概览¶

Total Time | 耗时: ~10 Minutes | 约10分钟
Key Services | 核心服务: Tencent Cloud (Domain) + Cloudflare (DNS/CDN/Security)
Cost Strategy | 成本策略: Low-cost TLDs + Free Tier CDN | 低价顶级域名 + 免费CDN层

📝 Step-by-Step Guide | 详细操作指引¶

Step 1: Domain Registration on Tencent Cloud | 腾讯云选购低价域名¶

Avoid expensive TLDs like .ai if you are on a budget. .online is a great, professional alternative. 预算有限时请避开 .ai 等昂贵后缀。.online 是一个既专业又实惠的替代方案。

Log in to Tencent Cloud Console | 登录腾讯云控制台。
Go to Domain Registration | 进入域名注册页面 (DNSPod)。
Search & Compare | 搜索心仪的域名。
💡 Tip: Search for your app name.
💡 Suggestion: Check prices for .online, .io, .co, or .xyz. .online often has promotions (e.g., ¥8-¥20 for the first year).
⚠️ Warning: .ai domains usually cost $60-80+/year.
Purchase & Verify | 购买并完成实名认证 (Required in China for purchase, but using Cloudflare DNS hides origin IP).

Step 2: Register on Cloudflare & Get DNS | Cloudflare注册并获取DNS¶

Cloudflare is the industry standard for DNS, CDN, and DDoS protection. Cloudflare 是DNS解析、CDN加速和DDoS防护的行业标准。

Sign Up/Log In | 访问 Cloudflare.com 注册或登录。
Add a Site | 点击右上角 "Add a site"。
Enter Domain | 输入你在腾讯云购买的域名 (e.g., my-ai-app.online) -> Continue。
Select Plan | 选择底部 Free Plan (免费版) -> Continue。
Review DNS | Cloudflare will scan existing records. Click Continue.
Get Nameservers | You will see two Nameservers provided by Cloudflare.
Example: amy.ns.cloudflare.com & bob.ns.cloudflare.com
📋 Copy these! | 复制这两个地址！

Step 3: Update DNS in Tencent Cloud | 腾讯云替换DNS (Critical Step)¶

🔴 Crucial Step for Beginners: Many users forget this and wait forever for propagation. 🔴 新手易错点：很多用户忘记这一步，导致解析一直不生效。

Back to Tencent Cloud | 回到腾讯云/DNSPod 控制台。
Domain Management | 找到“我的域名”列表。
Modify DNS | 点击域名进入详情 -> 找到 "DNS服务器" (DNS Servers) -> 点击 "修改" (Modify).
Custom DNS | 选择 "自定义DNS" (Custom DNS).
Paste Cloudflare NS | 将 Cloudflare 提供的两个地址分别粘贴进去。
删除原有的腾讯云DNS地址。
Save | 保存更改。

Step 4: Enable SSL & Security on Cloudflare | Cloudflare开启SSL与安全防护¶

Wait for a few minutes (up to 24h, but usually ~10 mins). Cloudflare will send an email saying "Status Active". 等待几分钟（通常约10分钟），Cloudflare 会发送邮件通知域名已激活。

Check Status | 在 Cloudflare 首页看到域名状态变为 "Active" (绿色)。
SSL/TLS Setup | 点击左侧菜单 SSL/TLS:
Set encryption mode to Full or Full (strict).
Flexible: Use only if your origin server cannot support SSL (not recommended).
Always Use HTTPS | Go to SSL/TLS -> Edge Certificates.
Toggle Always Use HTTPS to On.
Security Settings | Go to Security -> WAF.
You can create rules to block specific countries or high-risk IPs if needed.

🌟 Why This Stack? | 为什么选择这个组合？¶

Feature	Tencent Cloud Domain	Cloudflare DNS/CDN
**Payment	支付**	WeChat/Alipay supported (Convenient)
**Speed	速度**	Fast registration process
**Security	安全**	Basic domain lock
**Cost	成本**	Competitive first-year prices

✅ Summary | 总结¶

By separating the Domain Registrar (Tencent Cloud) from the DNS/Service Provider (Cloudflare), you get the best of both worlds: easy payment and management in China, combined with world-class global performance and security. 通过将域名注册商（腾讯云）与DNS/服务提供商（Cloudflare）分离，你获得了两全其美的效果：国内便捷的支付与管理，结合世界级的全球性能与安全防护。
