Fastly

Fastly is a cloud computing platform that provides content delivery network (CDN), edge computing, and web application firewall (WAF) services. It enables developers to deliver content quickly and securely by caching it at edge locations close to users, while also offering serverless computing capabilities through its edge compute platform. The platform is designed for high performance, real-time control, and scalability, making it popular for dynamic and interactive web applications.

Also known as: Fastly CDN, Fastly Edge Cloud, Fastly Compute@Edge, Fastly WAF, Fastly VCL

🧊Why learn Fastly?

Developers should learn and use Fastly when building high-traffic websites, APIs, or applications that require low-latency content delivery, real-time caching control, and edge computing capabilities. It is particularly valuable for e-commerce sites, media streaming services, and SaaS platforms that need to handle global traffic spikes, implement security features like DDoS protection, and optimize performance through programmable edge logic. Fastly's Varnish Configuration Language (VCL) and Compute@Edge (using WebAssembly) allow for custom caching rules and serverless functions at the edge.
