Content Delivery Networks (CDNs)

Content Delivery Networks (CDNs)

A CDN is a distributed network of servers that delivers content to users based on their geographic location. CDNs improve website speed, performance, and availability.

How CDNs Work

When a user requests a webpage, the CDN delivers static content (images, CSS, JS) from the nearest server. This reduces load time and server stress.

Benefits of CDNs

  • Faster load times
  • Improved user experience
  • Increased availability and uptime
  • Better global reach
  • Enhanced security (e.g. DDoS protection)

Popular CDN Providers

  • Cloudflare
  • Amazon CloudFront
  • Fastly
  • Akamai
  • Google Cloud CDN

Conclusion

CDNs are a crucial part of modern web infrastructure. Whether you're running a blog or a global SaaS platform, using a CDN significantly improves performance and user experience.

It allows code written in multiple programming languages to run on the web at near-native speed. WASM is a game changer, especially for performance-heavy web applications like games, video editing, simulations, and CAD tools. Why WebAssembly? Traditionally, JavaScript has been the only programming language capable of running in browsers. Although powerful, JavaScript isn’t always the best choice for performance-intensive applications. WebAssembly fills this gap by providing a fast, compact binary format that the browser can run alongside JavaScript. Supported Languages C/C++ Rust Go (with limitations) AssemblyScript (a TypeScript subset) How WASM Works WASM code is compiled ahead of time into a binary format, which is then fetched and executed by the bro...
