Objective

The Enterprise-Scale architecture provides prescriptive guidance coupled with Azure best practices, and it follows design principles across the critical design areas for organizations to define their Azure architecture. It will continue to evolve alongside the Azure platform and is ultimately defined by the various design decisions that organizations must make to define their Azure journey.

The Enterprise-Scale architecture is modular by design and allows organizations to start with foundational landing zones that support their application portfolios, and the architecture enables organizations to start as small as needed and scale alongside their business requirements regardless of scale point.

---

The Enterprise-Scale architecture represents the strategic design path and target technical state for your Azure environment.

---

Not all enterprises adopt Azure in the same way, so the Enterprise-Scale architecture may vary between customers. Ultimately, the technical considerations and design recommendations of the Enterprise-Scale architecture may lead to different trade-offs based on the customer's scenario. Some variation is expected, but if core recommendations are followed, the resulting target architecture will put the customer on a path to sustainable scale.

The Enterprise-Scale reference implementations in this repository are intended to support Enterprise-Scale Azure adoption and provides prescriptive guidance based on authoritative design for the Azure platform as a whole.

Key customer landing zone requirement	Enterprise-Scale reference implementations
Timelines to reach security and compliance requirements for a workload	Enabling all recommendations during setup, will ensure resources are compliant from a monitoring and security perspective
Provides a baseline architecture using multi-subscription design	Yes, for the entire Azure tenant regardless of customer’s scale-point
Best-practices from cloud provider	Yes, proven and validated with customers
Be aligned with cloud provider’s platform roadmap	Yes
UI Experience and simplified setup	Yes, Azure portal
All critical services are present and properly configured according to recommend best practices for identity & access management, governance, security, network and logging	Yes, using a multi-subscription design, aligned with Azure platform roadmap
Automation capabilities (IaC/DevOps)	Yes: ARM, Policy, GitHub/Azure DevOps CICD pipeline option included
Provides long-term self-sufficiency	Yes, enterprise-scale architecture -> 1:N landing zones. Approach & architecture prepare the customer for long-term self-sufficiency, the RIs are there to get you started
Enables migration velocity across the organization	Yes, enterprise-scale architecture -> 1:N landing zones, Architecture includes designs for segmentation and separation of duty to empower teams to act within appropriate landing zones
Achieves operational excellence	Yes. Enables autonomy for platform and application teams with a policy driven governance and management

Conditions for success

To fully leverage this reference implementation in this repository, readers must have a collaborative engagement with key customer stakeholders across critical technical domains, such as identity, security, and networking. Ultimately, the success of cloud adoption hinges on cross-discipline cooperation within the organization, since key requisite Enterprise-Scale design decisions are cross cutting, and to be authoritative must involve domain Subject Matter Expertise (SME) and stakeholders within the customer. It is crucial that the organization has defined their Enterprise-Scale Architecture following the design principles and critical design areas.

It is also assumed that readers have a broad understanding of key Azure constructs and services in order to fully contextualize the prescriptive recommendations contained within Enterprise-Scale.

Deploying Enterprise-Scale Architecture in your own environment

The Enterprise-Scale architecture is modular by design and allows customers to start with foundational Landing Zones that support their application portfolios, regardless of whether the applications are being migrated or are newly developed and deployed to Azure. The architecture can scale alongside the customer's business requirements regardless of scale point. In this repository we are providing the following five templates representing different scenarios composed using ARM templates.

Reference implementation	Description	ARM Template	Link
Contoso	On-premises connectivity using Azure vWAN		Detailed description
AdventureWorks	On-premises connectivity with Hub & Spoke		Detailed description
WingTip	Azure without hybrid connectivity		Detailed description
Trey Research	On-premises connectivity with Hub and Spoke for small Enterprises		Detailed description
Azure Gov	Reference implementation that can be deployed to Azure gov and includes all options in a converged experience		N/A
