Serverless Functions
9 providers in this category.
Serverless function platforms run individual functions on demand and bill per execution, scaling to zero when idle. They fit event-driven workloads, lightweight APIs, and glue code where you don't want to manage or pay for always-on servers. The deciding factors are cold-start behavior, runtime and language support, execution limits, and the per-invocation pricing model.
