Enterprise Deployment: Sharing Experiences In E-commerce And ERP Deployment Of Alibaba Cloud Hong Kong Servers In Singapore

1.

Principles for overall architecture selection and deployment

- Goal: Ensure stable front-end e-commerce, high availability of ERP backend, and real-time data synchronization.
- Region selection: Hong Kong node handles Chinese mainland/Hong Kong/Macau/Taiwan traffic, Singapore node handles Southeast Asia traffic and backup.
- Service split: Front-end static uses CDN, application layer uses ECS/SLB, database runs RDS/backup to OSS.
- Security First: Deploys Alibaba Cloud DDoS protection, WAFs, and security groups to minimize open ports.
- Operation and maintenance requirements: log centralization, monitoring alerts, and automatic scaling rules covering e-commerce promotion peaks.

Server configuration and bandwidth example

- Production example (Alibaba Cloud Hong Kong ECS): 2 vCPU / 8 GB memory / 50 GB SSD, bandwidth 200 Mbps.
- Read-Write Separation Example (Singapore ECS): 4 vCPU / 16 GB Memory / 120 GB NVMe for batch synchronization and off-peak computing. <br />- Database (RDS for MySQL) :d b.m5.large, equivalent to 2 vCPU/8GB, master-slave latency < 100 ms.
- Cache (Redis): Redis.sentinel 4GB, used for session and hot product acceleration.
- Storage and Backup: OSS cold storage is used for historical orders, with snapshots taken once daily and backups retained for 30 days.

Real case: ABC e-commerce company migration experience

- Issue: Before migration, single-point architecture, page response time was 3.2 seconds when concurrent 10k was during the promotion period.
- Deployment solution: Hong Kong frontend + Singapore backend, using SLB for seven layers of loading, Alibaba Cloud CDN accelerating static resources.
- Security Policy: Anti-DDoS Pro and WAF have been launched to adapt and intercept abnormal traffic. <br /> - Result: Average page response dropped to 1.1s, 99% request latency < 300 ms.
- Operations benefits: failover time reduced from 2 hours to 5 minutes, with annual O&M costs reduced by about 18%.

Practical details of CDN and DDoS protection

- CDN configuration: All static resources are managed via Alibaba Cloud CDN, nodes cover Hong Kong, New Zealand, and Southeast Asia, with a cache hit rate target of > 85%.
- Protection Policy: Anti-DDoS Pro sets traffic alert thresholds and automatic blocking rules.
- WAF rule: blocks SQL injection, XSS, and common BOTs, enabling whitelisting and rate limits.
- Monitoring metrics: real-time monitoring of bandwidth utilization, peak concurrency, error rate (5xx), cache hit rate.
- Drills and Rollbacks: Conduct DDoS drills and traffic switching drills quarterly to ensure business continuity.

Performance data comparison (sample table).

- The table shows approximate indicators observed after migration and can serve as a reference for capacity planning.
- It is recommended to multiply the business peak by 1.5 as the safety factor.

Operation and cost optimization recommendations

- Elastic scaling strategy: Automatically scaling CPU/memory thresholds for stateless services.
- Reserved Instance to On-Demand Ratio: Long-term stable loads prioritize reserved instances to save 30%+ in costs.
- Traffic Tiering: High-frequency resources use CDN caching, and database read-write separation reduces master database pressure.
- Monitoring automation: Use cloud monitoring + custom alarm scripts to shorten fault response times.
- Compliance and Backup: Cross-region backup and offsite disaster recovery, with regular recovery drills to ensure RTO/RPO compliance.
