Hands-On Azure Labs: Building Redundant Cloud Solutions

In this lab, you will establish the second Virtual Network (vNet-East) and its accompanying subnet (Subnet-East) in the East US region. Having parallel virtual networks in different geographic regions is crucial for redundancy and high availability. By completing this lab, you will ensure that your cloud environment can support resources and services in both regions, preparing the foundation for cross-region load balancing and disaster recovery scenarios.

This brief video explains what you’ll deploy, why it matters, and how it fits into the project.

Lab Requirements

To complete this lab, you will:

• • Create a virtual network named vNet-East and place it in the RG-Lab resource group within the East US region.
  • Change the default address space to 10.1.0.0/16 to accommodate future resource deployments.
    • This provides a large pool of IP addresses for subnets and other network components as the project expands.
  • Modify the subnet configuration:
    • Remove the automatically created default subnet.
    • Create a new subnet named Subnet-East.
    • Assign Subnet-East a starting address of 10.1.1.0 with a /24 mask.
    • This defines the subnet address range as 10.1.1.0 through 10.1.1.255, dedicated for the East US virtual machines that will later serve as web servers.
  • After deployment, confirm that Subnet-East appears on the Subnets page of vNet-East.

Defining this custom subnet allows for more efficient traffic flow management, easier implementation of security policies, and optimized network performance for application workloads.

How This Lab Fits into the Overall Project

Deploying vNet-East and Subnet-East helps establish a structured and scalable network environment for the distributed web application that you’re deploying. This network will serve as the foundation for all virtual machines and services deployed in the East US region, ensuring secure and efficient communication between resources.

By the end of this lab, you will be able to:

• • Create a separate virtual network in the East US region.
  • Configure a custom subnet to ensure proper IP address management and isolation.
  • Understand multi-region networking strategies in Azure.
  • Prepare for later labs that leverage geographically distributed resources.

The skills you gain in this lab map directly to key objectives in the following Azure certifications:

• • AZ-104 (Azure Administrator): Validates your proficiency in creating and managing network resources across different regions.
  • AZ-305 (Azure Solutions Architect): Enhances your ability to design and implement robust multi-region architectures for availability and resiliency.
