Vercel's Fluid compute is a next-generation compute model designed to handle modern workloads with real-time scaling, cost efficiency, and minimal overhead. It addresses the inefficiencies of traditional serverless architectures by dynamically adjusting to traffic demands, reusing existing resources before provisioning new ones. The Vercel Functions router orchestrates function execution to minimize cold starts, maximize concurrency, and optimize resource usage. Fluid compute optimizes every request in real-time, routing efficiently, selecting the best compute, and scaling dynamically with a secure infrastructure design that enhances security and enables precise control over workload distribution and scaling decisions. By efficiently managing compute allocation, Fluid compute prevents unnecessary cold starts and scales capacity only when needed, reducing costs by up to 85% for projects enabled with this technology.
