CDN vs Self-Hosted Caching

Developers should use a CDN when building websites or applications that require fast, reliable content delivery to a global audience, such as e-commerce sites, media streaming platforms, or SaaS products meets developers should use self-hosted caching when they need fine-grained control over caching policies, data privacy, or cost management in environments with predictable traffic patterns or strict compliance requirements. Here's our take.

CDN

Nice Pick

Developers should use a CDN when building websites or applications that require fast, reliable content delivery to a global audience, such as e-commerce sites, media streaming platforms, or SaaS products

Pros

• Related to: web-performance-optimization, caching-strategies

Cons

• Specific tradeoffs depend on your use case

Self-Hosted Caching

Developers should use self-hosted caching when they need fine-grained control over caching policies, data privacy, or cost management in environments with predictable traffic patterns or strict compliance requirements

Pros

• It's ideal for applications with high read-to-write ratios, such as e-commerce platforms, content management systems, or APIs serving static or semi-static data, where reducing database queries is critical for performance
• Related to: redis, memcached

Cons

• Specific tradeoffs depend on your use case
