About This Book
The Azure CIDR Architecture Standard for Enterprise Production Environments establishes Standardized Architectural Guidance for designing, allocating, and governing IPv4 Address Space across Microsoft Azure Production Environments. The Objective of this Reference is to provide a Consistent Enterprise Framework for Virtual Network and Subnet Design that supports scalability, security, Hybrid Connectivity, Automation, Disaster Recovery, and Long-Term Operational Sustainability.
Rather than allocating Address Space based solely on current requirements, this Standard adopts a Lifecycle-Driven Approach that emphasizes Long-Term Capacity Planning, Hierarchical Address allocation, Predictable Subnet Placement, Route Summarization, and Reserved Growth Capacity. Standardized CIDR allocation enables organizations to simplify Network Administration, improve Infrastructure as Code deployments, reduce Address Fragmentation, accelerate New Environment Provisioning, and support future business growth without Disruptive Network Redesign.
The standards contained in this reference apply to Enterprise Production Environments regardless of industry or workload type. They establish recommended subnet sizes, delegation requirements, Network Placement, Routing Considerations, Security Integration, Governance controls, monitoring requirements, and capacity-planning guidance for Azure networking Services Commonly Deployed in Enterprise Environments.
Each chapter follows a Consistent Enterprise Architecture Framework that includes:
- Purpose
- Architecture Objectives
- Architecture Principles
- Reference Architecture
- Enterprise Standard
- Mandatory Rules
Together, these sections define standardized guidance for designing Azure Networking components that are Secure, Scalable, Supportable, and Operationally Consistent Across Subscriptions, Landing Zones, Business Units, and Azure Regions.
This reference covers CIDR Architecture Standards for the following Azure Networking Services and Enterprise Network Design Scenarios:
- Azure Virtual Network
- General Workload Subnets for Virtual Machines and Virtual Machine Scale Sets
- Azure Application Gateway
- Azure Firewall
- Azure Bastion
- Azure VPN Gateway
- Azure ExpressRoute Gateway
- Azure Route Server
