How to Manage the ML Lifecycle

Most ML systems don’t fail because of poor models. They fail at the systems level! You can have a world-class model architecture, but if you can’t reproduce your training runs, automate deployments, or monitor model drift, you don’t have a reliable system. You have a science project. That’s where MLOps comes in. 🔹 𝗠𝗟𝗢𝗽𝘀 𝗟𝗲𝘃𝗲𝗹 𝟬 - 𝗠𝗮𝗻𝘂𝗮𝗹 & 𝗙𝗿𝗮𝗴𝗶𝗹𝗲 This is where many teams operate today. → Training runs are triggered manually (notebooks, scripts) → No CI/CD, no tracking of datasets or parameters → Model artifacts are not versioned → Deployments are inconsistent, sometimes even manual copy-paste to production There’s no real observability, no rollback strategy, no trust in reproducibility. To move forward: → Start versioning datasets, models, and training scripts → Introduce structured experiment tracking (e.g. MLflow, Weights & Biases) → Add automated tests for data schema and training logic This is the foundation. Without it, everything downstream is unstable. 🔹 𝗠𝗟𝗢𝗽𝘀 𝗟𝗲𝘃𝗲𝗹 𝟭 - 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗲𝗱 & 𝗥𝗲𝗽𝗲𝗮𝘁𝗮𝗯𝗹𝗲 Here, you start treating ML like software engineering. → Training pipelines are orchestrated (Kubeflow, Vertex Pipelines, Airflow) → Every commit triggers CI: code linting, schema checks, smoke training runs → Artifacts are logged and versioned, models are registered before deployment → Deployments are reproducible and traceable This isn’t about chasing tools, it’s about building trust in your system. You know exactly which dataset and code version produced a given model. You can roll back. You can iterate safely. To get here: → Automate your training pipeline → Use registries to track models and metadata → Add monitoring for drift, latency, and performance degradation in production My 2 cents 🫰 → Most ML projects don’t die because the model didn’t work. → They die because no one could explain what changed between the last good version and the one that broke. → MLOps isn’t overhead. It’s the only path to stable, scalable ML systems. → Start small, build systematically, treat your pipeline as a product. If you’re building for reliability, not just performance, you’re already ahead.

If you are working in a big tech company on ML projects, chances are you are working on some version of Continuous Integration / Continuous Deployment (CI/CD). It represents a high level of maturity in MLOps with Continuous Training (CT) at the top. This level of automation really helps ML engineers to solely focus on experimenting with new ideas while delegating repetitive tasks to engineering pipelines and minimizing human errors. On a side note, when I was working at Meta, the level of automation was of the highest degree. That was simultaneously fascinating and quite frustrating! I had spent so many years learning how to deal with ML deployment and management that I had learned to like it. I was becoming good at it, and suddenly all that work seemed meaningless as it was abstracted away in some automation. I think this is what many people are feeling when it comes to AutoML: a simple call to a "fit" function seems to replace what took years of work and experience for some people to learn. There are many ways to implement CI/CD/CT for Machine Learning but here is a typical process: - The experimental phase - The ML Engineer wants to test a new idea (let's say a new feature transformation). He modifies the code base to implement the new transformation, trains a model, and validates that the new transformation indeed yields higher performance. The resulting outcome at this point is just a piece of code that needs to be included in the master repo. - Continuous integration - The engineer then creates a Pull Request (PR) that automatically triggers unit testing (like a typical CI process) but also triggers the instantiation of the automated training pipeline to retrain the model, potentially test it through integration tests or test cases and push it to a model registry. There is a manual process for another engineer to validate the PR and performance reading of the new model.  - Continuous deployment - Activating a deployment triggers a canary deployment to make sure the model fits in a serving pipeline and runs an A/B test experiment to test it against the production model. After satisfactory results, we can propose the new model as a replacement for the production one. - Continuous training - as soon as the model enters the model registry, it deteriorates and you might want to activate recurring training right away. For example, each day the model can be further fine-tuned with the new training data of the day, deployed, and the serving pipeline is rerouted to the updated model.
