| description.long | A serverless compute service that automatically scales in response to demand and reduces to zero during idle periods. Execute code triggered by events from AWS services and external applications with built-in security, monitoring, and support for multiple programming languages. | A serverless platform enabling developers to deploy applications and scripts that run across Cloudflare's global infrastructure, scaling automatically from zero requests to millions, with billing based on actual execution time rather than reserved capacity. |
