Serverless computing allows developers to build applications without managing servers. Cloud providers handle infrastructure, letting developers focus on code and business logic.
Functions as a Service (FaaS) runs code in response to events. You write functions that execute when triggered, paying only for actual execution time. This model eliminates idle server costs.
Serverless scales automatically based on demand. During traffic spikes, the platform provisions resources as needed. When traffic drops, so do costs. This elasticity suits variable workloads well.
