Experience
MLOps Platform on AWS using Kubeflow for Model Deployment
The code of an ML model, ML pipeline, infrastructure, and dependencies (all of which are stored and versioned in Git), as well as a dataset from a centralized feature store, are compiled into the model by ML Orchestrator to generate logs, metrics, alerts, and data for storage and analysis.
Continuous delivery and experimentation workflows are dynamically integrated. This setup allows us to use the same pipeline to initiate experiments manually and automatically. These are triggered from Git hooks and CI/CD tools for continuous integration and deployment.
