Case Study: Milliman achieves accelerated, scalable cloud actuarial modeling and reporting with Microsoft Azure

Top Actuarial Firm Transforms the Insurance Industry with Cloud Modeling Platform

Milliman, a global actuarial firm based in Seattle, provides modeling and risk services to insurers but faced rising costs and complexity from on‑premises grid computing. Its legacy MG‑ALFA workflows and growing regulatory reporting demands left actuaries spending an estimated 70% of their time on data preparation, running reports, and managing infrastructure rather than analysis.

To solve this, Milliman launched Integrate, a cloud‑based SaaS on Microsoft Azure that leverages Azure Data Factory and HDInsight to automate ETL, scale compute on demand, and run large stochastic simulations. The move accelerated time‑to‑market, cut IT costs, and unlocked massive capacity—client compute hours rose over 600% to about 45 million hours on grids up to 50,000 cores with a >99.99% job completion rate—freeing actuaries to focus on insight and delivering secure, reliable reporting at lower cost.
