Building Resilient Web Apps with CDN and Caching Web apps today must respond quickly, even when traffic rises or users are far away. A CDN plus smart caching makes this possible by delivering content from nearby locations and reusing stored data. This combo also helps you handle traffic spikes without overloading your servers. CDNs place copies of assets at edge locations around the world. When a user requests a page, the edge server serves images, CSS, and scripts from the closest spot. This cuts latency, saves bandwidth, and lowers load on your origin. A well-configured CDN can also absorb some kinds of traffic bursts during a sudden spike. ...

Caching Strategies to Speed Up Web Apps Caching is a simple idea with big results. When you store copies of responses, users get faster pages and your servers handle fewer repeated requests. The trick is to cache wisely: different layers, different data, and clear rules for when to refresh. Caching works best when you balance freshness and speed. Static assets like images and scripts can live longer in caches, while frequently changing data needs shorter lifetimes or smart revalidation. The goal is to serve correct content without repeating heavy work on every request. ...

Web Servers Performance Tuning and Caching Web servers handle many requests every second. Small tuning choices can reduce latency, lower resource use, and improve user experience. This guide shares practical ideas you can apply to popular servers like Nginx and Apache, with simple tests to see real results. Caching is a core tool. It lets the server answer quickly by reusing previous responses. A clear policy for what to cache and for how long helps browsers, gateways, and CDNs work together. ...
