This service lets developers write and execute small components (functions) on-demand, with automatic scaling and no server provisioning required. It supports common runtimes (Node.js, Go, Python, PHP, Rust), and integrates with triggers like HTTP webhooks, scheduled tasks, and message queues to invoke functions. Deployments are executed on Knative (an open-source Kubernetes-based FaaS framework), providing portability and the ability to run functions across different infrastructures. Pricing is usage-based: users only pay for execution time, as the platform automatically scales functions up and down based on demand. Scaleway’s documentation notes that functions run in EU data centers with optional VPC integration and sandboxed security, fitting use cases like microservices, automation tasks, and APIs.
