The site has now fully migrated to Alibaba Cloud, using all services provided by Alibaba Cloud, achieving CDN acceleration for static resources and separation of program and database, using the following Alibaba services: Cloud Shield, Cloud Monitor, Elastic Compute Service (ECS), Relational Database Service (RDS), Object Storage Service (OSS), Content Delivery Network (CDN). Domain resolution uses DNSpod Personal Pro edition, not Alibaba Cloud resolution — after all, DNSpod is still number one nationwide, with HiChina second. Here’s the architecture diagram: [caption id="" align=“aligncenter” width=“1000”]
NEILREN.COM Web Service Architecture Diagram (Alibaba Cloud)[/caption] Detailed explanation:
- Domain uses DNSpod Personal Pro edition, SLA: 99%
- Cloud Shield defense, combined with Alibaba Cloud’s powerful data analysis capabilities, provides customers with DDoS protection, host intrusion prevention, and a full set of security services such as vulnerability detection and trojan detection.
- Cloud Monitor, an open monitoring platform, can monitor your site and servers in real time and provide various alert methods (SMS, Wangwang, email, callback interface) to ensure timely warning, safeguarding the normal operation of your site and servers.
- Elastic Compute Service (ECS), an elastically scalable computing service that helps you quickly build more stable, secure applications, improve Ops efficiency, reduce IT costs, and let you focus more on core business innovation, SLA: 99.95%
- Relational Database Service (RDS), an out-of-the-box, stable, reliable, elastically scalable online database service, with multiple security protections and a complete performance monitoring system, and professional database backup, recovery, and optimization solutions, SLA: 99.95%
- Content Delivery Network (CDN), distributing source content to all nodes nationwide, reducing the latency for users to view objects, improving users’ access response speed and site availability, solving problems such as small network bandwidth, large user access, and uneven node distribution.
- Object Storage Service (OSS), Alibaba Cloud’s massive, secure, and highly reliable cloud storage service. The platform independence of the RESTFul API, elastic expansion of capacity and processing power, pay-as-you-go by actual capacity, SLA: 99.9%
This way, site availability is guaranteed at 98.8%; adding my own maintenance and server restarts, site availability is basically above 95%, which can be said to be quite reliable. [caption id="" align=“aligncenter” width=“1353”]
Alibaba Cloud services used by Ren Fei[/caption] But Alibaba Cloud isn’t all good — some designs are imperfect, and prices are high. My stack adds up to at least 150–200 RMB per month in renewal expenses, more than 10 times a virtual host, but it offers much more than a virtual host — I can run unlimited sub-sites, have an independent IP, bind SSL certificates, etc. I’ll post the complaints another day; first let’s look at what I implemented:
Domain resolution uses DNSpod Personal Pro edition, saving a lot of worry — DNSpod is fairly stable. [caption id="" align=“aligncenter” width=“838”]
Ren Fei uses DNSpod Personal Pro edition[/caption] The bound SSL certificate — the site backend requires client digital certificate verification to access; knowing the login password isn’t enough to access. [caption id="" align=“aligncenter” width=“822”]
The site backend requires client certificate verification[/caption] Server ports listen to my own will — open whichever I want.
If you have any other questions, feel free to contact me. That’s my report for now.
