May 1, 2024 Updated July 10, 2025 16 minute read

Serverless functions are a cloud-based computing model that helps developers build applications without managing servers or infrastructure. It allows developers to focus on developing business logic without worrying about scaling, patching, or maintaining servers. Serverless functions are event-driven, meaning they only execute when triggered by a specific event, such as an HTTP request, a database change, or a message from a queue.
