Analyze server logs to detect performance issues, errors, and unusual patterns that could indicate underlying problems.

Importance of CDN and Caching

Content Delivery Networks (CDNs)

CDNs distribute content across a geographically dispersed server network, ensuring users access the content from the nearest server. This reduces latency and improves load times. CDNs handle large volumes of traffic by offloading requests from the origin server, enhancing the website's ability to scale and manage spikes in traffic. By distributing content across multiple locations, CDNs provide redundancy, ensuring that content remains available even if one or more servers fail.

Caching Mechanisms

Enable browser caching to store static files such as images, CSS, and JavaScript locally on users' devices. This reduces the need to re-download unchanged content, speeding up load times.

Implement server-side caching strategies, such as object caching, page caching, and opcode caching, to reduce the server's load and speed up response times.

• Object Caching: Cache frequently accessed objects in memory to reduce database load and improve retrieval times.
• Page Caching: Cache entire pages or page fragments to serve static content quickly, bypassing the need for dynamic content generation on each request.
• Opcode Caching: Cache compiled PHP code to avoid repeated parsing and compilation, improving the performance of PHP-based applications.

Edge Caching

Utilize edge servers CDNs provide to cache content closer to the end users, further reducing latency and improving performance.

Employ techniques to cache dynamic content intelligently, using rules and conditions to determine when to serve cached content versus fresh content.

Cache Invalidation and Expiration

Implement cache invalidation policies to ensure that outdated content is refreshed appropriately. Use cache-busting techniques for assets that change frequently.
Set appropriate expiration headers for different types of content to control how long they should be cached, balancing performance with the need for up-to-date content.
