Our proposed solution focuses on implementing a cloud network infrastructure in Microsoft Azure, designed to meet the needs of organizations requiring a clear separation between production and development environments. The Azure infrastructure deployed includes the following key components:

1. Virtual Network (VNET): We will set up a Virtual Network (VNET) in Azure to create a logical and secure isolation of the network infrastructure. This VNET provides a robust foundation for connecting resources deployed in Azure.

2. Production Subnet: Within the VNET, a subnet dedicated to production environments will be established. This subnet is designed to host critical services and applications that require high performance and availability. Resources within this subnet will be effectively protected and isolated.

3. Development Subnet: Likewise, a subnet specific to development environments will be created. In this subnet, applications can be tested and developed, enabling development teams to work independently without impacting the stability of production systems.

4. Production Virtual Machine: In the production subnet, a virtual machine (VM) will be deployed to host critical applications. This VM will be configured to have access through a public IP address, allowing for remote administration and access to services provided by this VM.
