How To Optimize The Access Performance Of Tencent Cloud's Malaysia Servers By Combining CDN And Load Balancing

1.

Overview: Why combine CDN and load balancing in Malaysia

• Malaysian users are sensitive to latency, especially on the homepage and interface responses.
• CDN caches static resources, load balancing delivers dynamic requests, and the two complement each other.
• Using Tencent Cloud's CDN and CLB can mitigate traffic peaks and DDoS attacks at the edge.
• Proper configuration can significantly reduce TTFB and page load times.
• Especially important for e-commerce, media, and API services, which can improve user conversion rates and stability.

Key Points in Infrastructure Design

• Deployed CVM as the origin in Malaysia, enabling international/local bandwidth optimization.
• Distribute static resources (images, JS, CSS) to edge nodes via Tencent Cloud CDN.
• Use load balancing (CLB) to perform seven- or four-layer shunting and health checks among multiple CVMs.
• Configure cross-availability zone instances to ensure disaster recovery and high availability.
• Enable health checks and session maintenance (if necessary), and set appropriate backend weights.

Key performance indicators and tuning strategies

• Metrics: Average response latency (ms), TTFB (ms), Requests per second (RPS), packet loss rate, and availability.
• Optimized DNS resolution: Use Tencent Cloud DNSPod or resolve to CDN domains to reduce first hops.
• Caching Strategy: Set long caches for static resources, while dynamic APIs use short caches or cache key strategies.
• Load balancing strategy: Select appropriate scheduling based on minimum connections, polling, or source IP hash.
• Network optimization: Enable TCP acceleration, HTTP/2, or QUIC to improve concurrency and loading speeds.

Configuration examples and specific data demonstrations

• Source configuration example: CVM 4 vCPU / 8 GB memory / 40 GB SSD / public bandwidth 200 Mbps.
• CDN settings: caching rules, return policies, HTTPS certificates, compression and prefetching.
• CLB setup: Backend pool for 2 availability zones, each deploying 3 CVMs, health check interval 5s, timeout 3s.
• DDoS Protection: Activates Tencent Cloud's DDoS protection basic package for automatic elastic cleaning of sudden traffic incidents.
• Performance Comparison (Example Data): The table below shows typical metrics before and after activation. ). < td style="text-align:center;">1.8s< td style="text-align:center;">0.6s< td style="text-align:center;">800< td style="text-align:center;">3000

Real-life Case: Malaysian e-commerce customer practice

• Background: A cross-border e-commerce platform launched a flash sale event in Malaysia, causing frequent traffic restrictions and sharp increases in latency for the original single-machine CVM.
• Solution: Integrate Tencent Cloud CDN + CLB, deploy 3× CVM (4 cores 8GB) in multiple CAN zones, bandwidth 200Mbps.
• Configuration details: 100% static cache, API frequency limiting and circuit breaking, CLB health check 5s.
• Performance: Concurrency peaks steadily scaled from 1000 RPS to 3500 RPS, and page load time dropped from 1.9s to 0.5s.
• Experience: Reserved bandwidth and elastic scaling strategies, combined with log monitoring (TSF/CM) to quickly pinpoint bottlenecks.

Operation and security recommendations

• Routine monitoring: Connected to Tencent Cloud monitoring, configure alarm thresholds (CPU, bandwidth, response time).
• Automatic capacity expansion: Automatically scaling backend CVM based on RPS and CPU, avoiding manual intervention.
• Security Protection: Enable advanced WAF and DDoS protection, set whitelist/blacklist and rate limits.
• Disaster recovery drills: Regularly conduct traffic switching and fault recovery drills to verify CDN respawn and CLB fault tolerance.
• Cost control: Adjust bandwidth packets and cache hits as needed to avoid unnecessary public network traffic overhead.
