The JAMstack, a software architecture, aims to abstract configuration in favor of a streamlined workflow where complexity can be built-in piecemeal or outsourced entirely. It seeks to reduce cognitive burden and enable developers to better reason about logic in their applications. The JAMstack's key components include Build Automation, Event Triggers/Webhooks, and Serverless Functions. These features allow for an automated build process, event-driven architecture, and scalable infrastructure, respectively. By leveraging these technologies, developers can create fast and secure sites with reduced complexity and cost.
