How to use IBM Cloud Code Engine to create a backend API for dynamic content in your static website hosted on IBM Cloud Object Storage.
The backend API to create or retrieve the guestbook is a serverless app. The app is automatically scaled, depending on the workload and within its configured limits. If you expect few requests, it could automatically scale down to zero app instances (and not incur charges). In contrast, if you expect many requests and a high load — maybe not for a guestbook but for a discussion forum — you can configure some minimum instances and a higher upper boundary:
To deploy your own guestbook based on a static website with a serverless backend API, follow the instruction in the new tutorial: Serverless web application and API with Code Engine. The tutorial uses a pre-built container image for the app for ease of use. Alternatively, you could build your own container image using the source code provided in the GitHub repository serverless-guestbook.
