Migrating Your API Domain to a CDN with 1-Second Caching Strategies

Migrating Your API Domain to a CDN with 1-Second Caching Strategies

Understanding the Challenge  

APIs serve as the backbone of modern applications, enabling seamless communication between services. However, slow API response times and high latency can significantly degrade user experience and increase infrastructure costs.

Key challenges organizations face include:

  • High latency due to geographically dispersed users.

  • Unpredictable API load spikes leading to server strain.

  • Cache inefficiency with frequent duplicate requests.

  • Security risks from bot abuse and DDoS attacks.

For businesses handling millions of API requests daily, ensuring ultra-fast response times while maintaining security and reliability is paramount. Leveraging a CDN with 1-second caching strategies provides a robust solution to these challenges.

How VergeCloud Helps  

1. Edge Caching for API Acceleration  

What it is:
VergeCloud’s CDN caches API responses at its global PoPs, reducing the need for repeated backend queries.

How it helps:

  • Delivers cached API responses in under 50ms to users worldwide.

  • Reduces origin server load by up to 80%, improving efficiency.

  • Supports granular TTL (Time-to-Live) settings, ensuring frequent API updates remain fresh while leveraging caching benefits.

  • Implements stale-while-revalidate (SWR) to serve slightly outdated cache while fetching fresh data in the background.

2. Smart Request Routing and Load Balancing  

What it is:
VergeCloud uses AI-powered traffic steering and load balancing for API endpoints.

How it helps:

  • Dynamically routes API requests to the nearest, healthiest PoP for minimal latency.

  • Implements weighted load balancing across multiple API servers to distribute traffic intelligently.

  • Ensures failover redundancy, rerouting traffic in case of server downtime.

3. Dynamic Content and Personalized API Caching  

What it is:
Unlike static content caching, VergeCloud allows custom cache rules for API responses based on parameters, headers, and authentication tokens.

How it helps:

  • Enables API responses to be cached for specific user sessions.

  • Supports token-based caching while preventing sensitive data leaks.

  • Reduces API request duplication, improving overall API response efficiency.

4. API Security & DDoS Mitigation  

What it is:
VergeCloud provides a multi-layered security model with WAF, bot mitigation, and rate limiting for API protection.

How it helps:

  • Detects and blocks bad bot traffic that mimics legitimate API requests.

  • Rate limits abusive clients, preventing API exhaustion.

  • Provides zero-trust security models for authenticated API endpoints.

  • Shields APIs from Layer 3-7 DDoS attacks with up to 3 Tbps mitigation capacity.

5. HTTP/3 and TLS Optimization  

What it is:
VergeCloud fully supports HTTP/3 with QUIC and TLS session resumption for API communications.

How it helps:

  • Reduces handshake overhead for faster API response times.

  • Ensures secure and encrypted API transactions with minimal performance trade-offs.

  • Enhances mobile API performance by improving packet loss recovery.
