The Vercel Edge network optimizes performance by providing robust personalization without compromising on speed, addressing the long-standing challenge of serving dynamic content to a global user base. The primary goal of Vercel's Frontend Cloud is to collect industry-best practices into one easy-to-use workflow, integrating new and better solutions as they come. Speed is crucial for businesses, with milliseconds making millions and 8% conversion rate lift tied to every 100ms shaved off load time. Personalization matters too, as users are loyal to brands that feel "get them" and 65% of business comes from existing customers. The Frontend Cloud solves these challenges by using a globally distributed server to asynchronously compute and granularly cache the result of user requests, providing consistent availability and optimizing for latency. It also allows for Incremental Static Regeneration, enabling caching at all levels of the user request lifecycle and running dynamic server-side JavaScript as close as possible to users with Edge Functions or Middleware. This enables top-speed, global personalization without sacrificing speed for dynamic content, boosting search engine relevancy and user engagement.
