Introduction
Content Delivery Networks (CDNs) are distributed systems of servers designed to deliver web content, applications, videos, APIs, and digital assets to users with high speed, reliability, and security. Instead of serving content from a single origin server, a CDN caches and delivers content from geographically distributed edge locations closer to end users. This significantly reduces latency, improves page load times, and enhances overall user experience.
CDNs play a critical role in modern digital infrastructure. They support high-traffic websites, streaming platforms, SaaS applications, e-commerce stores, and global enterprises by ensuring consistent performance even during traffic spikes. Common use cases include website acceleration, video streaming, software downloads, API delivery, DDoS mitigation, and edge computing. When choosing a CDN, users should evaluate global coverage, caching capabilities, performance optimization, security features, integration options, analytics, ease of configuration, and cost efficiency.
Best for:
CDNs are ideal for startups, SMBs, large enterprises, media companies, SaaS providers, e-commerce platforms, gaming companies, and any organization serving a global audience.
Not ideal for:
Small local websites with minimal traffic, intranet-only applications, or environments where content is accessed from a single geographic location may not require a full CDN solution.
