By offloading database queries to an object cache, site owners can significantly reduce the load on their RDS databases and improve overall site performance.
Page caching involves storing entire web pages as static HTML files that can be served directly to users without the need for dynamic page generation. This can be achieved using a caching plugin such as W3 Total Cache or WP Super Cache, which generates static HTML files from dynamic WordPress pages and serves them to users with minimal server processing. By implementing page caching, site owners can dramatically reduce page load times and improve scalability for high-traffic periods.
Database caching involves optimizing database queries and indexing to improve query performance and reduce latency. This can be achieved by using tools such as Amazon Aurora for high-performance MySQL databases or Amazon ElastiCache for in-memory caching of frequently accessed data. By optimizing database performance and reducing query latency, site owners can improve overall site responsiveness and user experience.
CDN caching involves caching static and dynamic content at edge locations around the world to reduce latency and improve content delivery for users in different geographic regions. This can be achieved by integrating CloudFront CDN with WordPress to cache images, videos, CSS files, and other static assets at edge locations close to users. By leveraging CDN caching, site owners can deliver content more quickly to users and reduce the load on their origin servers.
By implementing these caching strategies at different levels of the infrastructure, site owners can significantly improve WordPress performance on AWS and deliver a faster and more responsive user experience.
