Architecting ML Workloads at Scale: Part 1 – A Comprehensive Framework for Efficiently Managing the ML Lifecycle with Amazon SageMaker
Introduction:
Customers of all sizes and industries are using AWS to incorporate machine learning (ML) into their products and services. However, implementing security and governance controls remains a challenge when scaling ML workloads. To address these challenges, AWS has developed a framework for governing the ML lifecycle at scale. This framework provides guidance on multi-account environments, data governance, shared services, ML team environments, and observability. It is particularly beneficial for large enterprises, organizations with mature ML strategies, and companies in regulated industries. In this series, AWS will walk through the reference architecture and provide guidance on implementing the framework.

Customers across industries are embracing the power of machine learning (ML) on the Amazon Web Services (AWS) platform. However, they face challenges in implementing ML at scale, particularly in terms of security, data privacy, and governance controls. These challenges are crucial for mitigating risk and ensuring responsible use of ML-driven products.
Generative AI models have recently gained traction, further emphasizing the need for ML adoption in various sectors. While generative AI requires additional controls to filter out toxicity and prevent unwanted outcomes, the foundational elements for security and governance remain consistent with traditional ML.
Many customers have expressed the need for specialized knowledge and investment of up to 12 months to build a customized Amazon SageMaker ML platform that can provide scalable, reliable, secure, and governed ML environments for their lines of business (LOBs) or ML teams.
However, lacking a framework for governing the ML lifecycle at scale can pose challenges such as resource isolation, scaling experimentation resources, operationalizing ML workflows, scaling model governance, and managing security and compliance.
To address these challenges, AWS offers a framework for governing the ML lifecycle at scale, providing prescriptive guidance based on industry best practices and enterprise standards. This framework covers various aspects of the ML platform, including multi-account setup, security and networking foundations, data and governance foundations, shared governance services, ML team environments, and observability.
While this framework benefits all customers, it is especially advantageous for large enterprises, regulated industries, and global organizations looking to scale their ML strategies while maintaining control, compliance, and coordination across the organization.
Part one of this series focuses on the reference architecture for setting up the ML platform, while subsequent posts will provide detailed guidance on implementing different modules within the architecture.
The capabilities of the ML platform are categorized into four groups: building ML foundations, scaling ML operations, observing ML performance, and ensuring ML security. These serve as the foundation for the reference architecture discussed later in the article.
The framework for governing the ML lifecycle at scale enables organizations to embed security and governance controls throughout the ML lifecycle, reducing risks and accelerating ML adoption. Key features of the framework include account and infrastructure provisioning, self-service deployment of data science environments and ML operations templates, resource isolation, governed access to data, code management and governance, model registry and feature store, and end-to-end security and governance controls.
The functional architecture associated with the ML platform encompasses various AWS services, including AWS Organizations, SageMaker, AWS DevOps services, and a data lake. It considers multiple personas and services to effectively govern the ML lifecycle at scale.
Implementing the framework involves steps such as setting up multi-account foundations, establishing a data lake and catalog, provisioning ML shared services, federating access for ML teams, building and deploying models, and embedding security and governance controls at every stage.
In conclusion, the framework for governing the ML lifecycle at scale on AWS provides customers with the necessary tools and guidance to implement secure, reliable, and scalable ML environments. By adopting this framework, organizations can mitigate risks, accelerate ML adoption, and ensure responsible use of ML-driven products and services.
Conclusion:
Customers of all sizes and industries are embracing machine learning (ML) on AWS. However, implementing security, data privacy, and governance controls are still challenges. To address this, a framework for governing the ML lifecycle at scale has been developed. This framework provides guidance on setting up multi-account environments, establishing data governance foundations, creating shared services and governance controls, setting up ML team environments, and ensuring observability. It is particularly beneficial for large, mature, regulated, or global enterprises looking to scale their ML efforts. The framework enables organizations to embed security and governance controls throughout the ML lifecycle, reducing risk and accelerating ML adoption. The functional architecture of the ML platform, implemented using various AWS services, is also outlined. It is recommended to follow a step-by-step process to organize teams and services in order to effectively implement the framework. The reference architecture is divided into eight modules that address different aspects of governance in the ML lifecycle. Overall, this framework provides a comprehensive and scalable approach to building secure and governed ML environments on AWS.
