In this blog post, we will be going through the networking overview of the Azure Landing Zone. key design considerations and recommendations surrounding network typologies in Microsoft Azure. Design Element : Below are the design consideration for Azure networking and connectivity. Planning for IP Addressing Configure DNS Define an Azure Networking Topology Connectivity to Azure Connectivity to other cloud providers Planning for IP Addressing IP address planning is a vital first step when designing a network in Azure especially if you have a hybrid environment to avoid overlapping IP address space across on-premises environment and Azure. Design Considerations: Azure reserves 5 IP address with each subnet so factor in the address space when sizing the virtual networks.
