 # Azure Virtual Network concepts and best practices
 
-This article describes key concepts and best practices for Azure Virtual Network.
+Azure Virtual Network is a fundamental building block for your private network in Azure. It enables Azure resources to securely communicate with each other, the internet, and on-premises networks. A virtual network is similar to a traditional network that you'd operate in your own data center, but brings additional benefits of Azure's infrastructure such as scale, availability, and isolation.
 
-## Virtual network concepts
+Understanding virtual network concepts and following best practices helps you design robust, secure, and scalable network architectures. Whether you're migrating existing workloads to Azure or building new cloud-native applications, proper network design is essential for performance, security, and cost optimization.

+## Virtual Network concepts
 
 - **Address space:** When creating a virtual network, you must specify a custom private IP address space using public and private (RFC 1918) addresses. Azure assigns resources in a virtual network a private IP address from the address space that you assign. For example, if you deploy a VM in a virtual network with address space, 10.0.0.0/16, the VM is assigned a private IP like 10.0.0.4.
