Why Do You Need a Virtual Network Gateway? A Virtual Network Gateway is essential for establishing secure connectivity between your on-premises network and Azure Virtual Network (VNet). It acts as the VPN endpoint in Azure, encrypting traffic using IPsec/IKE tunnels. Without it, you cannot create a secure VPN tunnel to Azure. Why Use the Basic SKU? Cost-Effective:  The Basic SKU is the most affordable option, making it ideal for test, dev, or non-production environments. Quick Deployment:  Unlike higher SKUs that can take 30–45 minutes, the Basic SKU typically deploys in only  7–10 minutes . Sufficient for Small Workloads:  Supports basic VPN connectivity without advanced features like BGP or high throughput. Note:  The Basic SKU is no longer available in the Azure Portal UI, but you can still deploy it using PowerShell or Azure CLI. PowerShell Script to Deploy Basic SKU VPN Gateway Here’s how to create a Virtual Network Gateway with Basic SKU in an existing VNe...
