In the competitive world of e-commerce, personalization is king. A leading retail platform understood this well, relying on machine learning models to power its product recommendation engine. However, their models were becoming stale, leading to a noticeable drop in recommendation quality and user engagement. This is a classic MLOps challenge, and they partnered with Rkssh to solve it.

The Challenge: Manual Processes and Decaying Accuracy

The client's data science team was brilliant, but they were bogged down by operational toil. Their model retraining process was:

• Slow and Manual: Retraining was a quarterly, week-long effort involving data scientists and engineers, making it impossible to react quickly to market trends.
• Costly: The process consumed valuable data scientist hours that could have been spent on research and developing new models.
• Reactive: They often only realized a model was underperforming after key business metrics (like click-through rates) had already dropped.

The problem wasn't a lack of data science talent; it was a lack of MLOps automation. The gap between model development and reliable production operation was stifling innovation.

The Solution: An End-to-End MLOps Pipeline on AWS

We designed and implemented a fully automated, event-driven MLOps pipeline on AWS. The goal was to create a "self-healing" system for models that could detect performance degradation and trigger retraining without human intervention.

1. Production Model Monitoring: We deployed Prometheus to continuously monitor the live recommendation model. We tracked key metrics like model accuracy (precision@k) and, crucially, data drift—changes in the statistical properties of incoming user data.
2. Automated Retraining Trigger: An Alertmanager rule was configured to fire an alert when model accuracy dropped below a set threshold or when significant data drift was detected. This alert sent a webhook that triggered a GitLab CI/CD pipeline.
3. CI/CD for Machine Learning: The GitLab pipeline orchestrated the entire retraining workflow:
   • Fetches the latest training data from S3.
   • Spins up a training job on their Amazon EKS (Kubernetes) cluster.
   • Once training is complete, it packages the new model artifacts into a versioned Docker container.
   • Pushes the new container to Amazon ECR (Elastic Container Registry).
4. Safe Canary Deployments: The final stage of the pipeline initiated a canary release. The new model version was deployed to the EKS cluster, and ax-width: 600px"> Let's discuss how our expert services can help you achieve your most ambitious business goals.
