IA MLO case studies
IA MLO · Put your knowledge to work in context.
The Certified MLOps Engineer (CMOE) is a professional certification listed by IABAC - the International Association of Business Analytics Certification - within its Data Science certification track, alongside credentials such as Certified Data Scientist, Certified Data Engineer and Certified Machine Learning Expert. IABAC describes itself on its homepage as "a globally recognized Professional Association dedicated to growing and enhancing the field of applied Data Science and Business Analytics," and states that it certifies professionals "through rigorous assessments under guidelines of EU framework." The CMOE is aimed at practitioners who take machine learning models beyond notebooks: engineers, data scientists and platform specialists responsible for reproducible training pipelines, model packaging and versioning, deployment and serving, monitoring for drift and degradation, CI/CD and retraining automation, and governance of models in production. The IA MLO case studies are 5 cases and about 5,010 words.
1Silent schema change splits the online and offline feature definitions
A fraud-detection team serves a gradient-boosted model behind a REST endpoint at 900 requests/second. Features are computed twice: an Apache Flink job writes them into Redis for online serving, and a nightly Spark job writes Parquet into the warehouse for training.

A retail search team is rolling out ranking model v7 to replace v6. v6 serves 12,000 QPS at p99 95 ms against a 120 ms SLO.

A mid-sized lender retrains its application-default model on the first of each month. Default is 90+ days past due within 12 months of origination, so the earliest delinquent signal appears around day 30 and a label is not final until roughly 13 months after application.

A subscription company's churn model has been in production for 14 months. An internal audit selects it and demands the exact training dataset, code, hyperparameters, and evidence that re-running the pipeline reproduces artifact churn-xgb-2024-11-03 .

A document-classification service handles 250 requests per second at steady state, served by 6 GPU replicas on T4 cards. Each replica sustains roughly 42 requests per second at p99 280 ms against a 300 ms SLO.
