Product overview
Fastly is an edge cloud platform designed to provide content delivery network (CDN) services, security, and programmable edge computing to developers. Built on a powerful Varnish-based architecture, Fastly allows users to execute custom logic at the edge of the network, closer to the end-user. This approach aims to reduce latency and improve site performance by handling requests and data processing without constantly returning to a centralized origin server. The platform is known for its focus on developer control, offering an API-first design that integrates into existing CI/CD pipelines. Users can manage complex caching rules, perform instant purges of outdated content, and gain deep visibility into traffic through real-time logging and analytics. Beyond simple static content delivery, Fastly’s Compute@Edge environment supports languages like Rust, JavaScript, and Go, enabling the development of high-performance serverless applications. Security is a central component of the service, featuring a web application firewall (WAF), DDoS protection, and TLS encryption to safeguard data in transit. Fastly caters primarily to enterprise-scale organizations and high-traffic digital businesses that require granular control over their network traffic and content delivery strategies.
