You have developed an application for your company's products that utilizes a sequence of scikit-learn models to predict optimal pricing. The workflow consists of multiple steps, each handled by individual models that are also used in other workflows by team members. You aim to deploy this workflow with robust version control for each model as well as the entire workflow. The application needs to be scalable, with the ability to scale down to zero when not in use, to optimize compute resource utilization and reduce manual management efforts. What approach should you take?
