Solution

Marks & Spencer built its Microsoft solution to improve customer-personalization workflows. The previous solution for data science workloads relied on many manual processes, and Marks & Spencer wanted a faster, less labor-intensive way to get models into production. Key components included Azure Machine Learning ran model inference or heavy processing, and Azure Databricks ran model inference or heavy processing. Operational data flows into Azure Machine Learning, where Azure Machine Learning applies transformations and business logic before Azure Machine Learning delivers governed insights to teams across Marks & Spencer. The governed Microsoft stack gave Marks & Spencer a reusable foundation for ai and machine learning, data analytics while keeping deployment, security, and day-to-day operations inside the Microsoft estate. "Marks & Spencer has more than 30 million customers and large amounts of data that require systems that can scale to process it.

Solution architecture

3 components · 2 layers
  1. Compute
    • Azure Machine Learning Builds, trains, and operationalizes predictive models and machine-learning pipelines.
    • Azure Databricks Transforms large-scale datasets and runs analytics or model-processing jobs.
  2. Orchestration
    • Azure DevOps Supports deployment, testing, and release management for the Microsoft solution estate.

Architecture clues

  • Azure Databricks handles data processing, extraction, transformation, and aggregation, including accessing and writing data into and from Azure Data Lake Storage Gen 2 Azure Data Factory handles the orchestration of pipelines, the CI/CD pipeline is built on Azure DevOps , and Azure Machine Learning handles model training and optimization.
  • Building a robust machine learning system Now, the MLOps team can seamlessly manage two Azure Machine Learning environments-one for development, another for production-and the CI/CD pipeline makes deployments directly.
  • The CI/CD pipeline creates an efficient process that speeds up time to production through automated tests that help developers review code quality and perform bug fixes faster.
  • The new templates were integrated into the continuous integration/continuous delivery (CI/CD) pipeline so that deployments can be made directly in Azure Machine Learning.
