Azure Infrastructure Deployment Guide

A step-by-step technical breakdown of provisioning a secure hybrid cloud environment from scratch.

1. Subscriptions & Resource Groups

The foundation starts by attaching a Resource Group (RG) to an active Azure Subscription. This allows for unified billing and logical grouping. Use az group create --name MyRG --location eastus to initialize the container for all assets.

2. VNet & Subnet Segmentation

Create a Virtual Network (VNet) and carve out specific address spaces. We provision a Public Subnet (for gateways/load balancers) and a Private Subnet (for databases/app servers) to ensure architectural isolation.

3. NSGs & Route Tables

Implement Network Security Groups (NSG) to act as a distributed firewall. We attach unique NSGs to each subnet to control inbound/outbound traffic and configure User Defined Routes (UDR) in Route Tables to force traffic through specific appliances.

4. VM Provisioning (Linux/Win)

Deploying Virtual Machines into their respective subnets. Public VMs receive a Public IP, while Private VMs are restricted to internal IPs only, minimizing the attack surface while maintaining scalability.

5. Local Access: Bastion & VPN Solutions

To access Private VMs from a local laptop, we implement Azure Bastion for browser-based RDP/SSH or a Point-to-Site (P2S) VPN. This secures the management plane without exposing port 3389 or 22 to the public internet.
