Microsoft Azure naming conventions

by

In this Azure tutorial, we will discuss Microsoft Azure naming conventions. Apart from this, we will also discuss on the below topics

  • Naming a Resource in Azure
  • Re-commanded prefix For Azure Resources
  • Naming rules and restrictions for Azure resources

Microsoft Azure naming conventions

It is always best practice to follow the Microsoft Azure naming conventions while you are naming any of the Azure objects or Azure components.

Naming a Resource in Azure

It is always better to follow the Microsoft Azure naming conventions while naming a resource in Azure

  • When naming the resource, the name should contain some meaningful information.
  • For example, if we are naming a public IP resource for a development workload, the name should be pip-SharePoint-prod-centralus-005.
  • As you will see, the information is very clear here. The name contains public IP(pip) with the environment details(prod) and Region details(central us), etc.
  • In Azure, the resource name must be unique within its scope.
  • There are some restrictions on the length of the resource names.

Re-commanded prefix For Azure Resources

There are some prefixes recommended as part of Microsoft Azure naming conventions before the name of the Azure resources

Virtual network

  • The name should start with the prefix vnet-
  • The format for the name of the virtual network is vnet-<Subscription type>-<Region>-<###>
  • For example vnet-prod-centralus-003
  • As you will see here, the information is very clear vnet is the virtual network, prod is for the production environment, centralus is the region you belong to.

Subnet

  • The name should start with the prefix snet-
  • The format for the name of the Subnet is snet-<subscription>-<subregion>-<###>
