Enterprise-Scale is a reference architecture and set of landing-zone blueprints for building large, governed Azure estates. It codifies recommended patterns—network topology, identity integration, subscription and resource organization, policy assignment, and guardrails—so enterprises can provision repeatable, secure, and compliant environments for workloads. The project supplies deployable artifacts (Bicep/ARM/Terraform modules, examples, and documentation) to accelerate consistent deployments across regions and teams while embedding best practices for security, cost management, and operations. It also addresses cross-cutting concerns like monitoring, logging, backup, and role-based access control so tenants don’t rediscover the same integration work each time they stand up a service. For cloud platform teams, Enterprise-Scale reduces design debates and provides a baseline that can be extended to meet vertical or regulatory needs.
