Are you treating your Azure Virtual Network as just another checkbox during deployment? Discover why the VNet is actually the foundation of your entire cloud infrastructure and how to set it up correctly from day one. In this episode, we dive deep into the essential building blocks of Azure networking to help you move from guessing to designing.
We cover everything from choosing the right CIDR range to implementing a secure hub-and-spoke architecture. You will learn why your IP address space planning is critical for future growth and how to avoid common overlapping network conflicts. We also explore the importance of subnets for organization and security, ensuring your web servers, databases, and application logic stay isolated and protected.
By the end of this guide, you will understand how to manage traffic flow using Network Security Groups and User-Defined Routes. We also explain the difference between public and private IPs and how to use VNet peering to connect resources across different regions. Whether you are building a simple app or a complex hybrid environment, this video provides the roadmap you need for a solid Azure foundation.
