Deploy a serverless Python API to Scaleway Functions using CircleCI

Serverless platforms, like Scaleway Serverless Functions, enable developers to build and deploy APIs without managing servers, focusing solely on application logic while the platform handles tasks like scaling and maintenance. Scaleway supports multiple runtimes, including Python, and offers a generous free tier, making it ideal for various workloads. This guide illustrates how to leverage Scaleway Serverless Functions alongside CircleCI to create an automated CI/CD pipeline for a serverless Python API. It involves building an invoice validation API, packaging it for deployment, and setting up continuous deployment via CircleCI, ensuring that every code change is automatically tested and deployed. The tutorial also covers the necessary prerequisites, setting up a Python environment, implementing and testing the API logic, and deploying the packaged function using Scaleway CLI. After configuring CircleCI to automate testing and deployment, developers can push their code changes to GitHub, ensuring a streamlined and modern cloud-native workflow.
