Resource naming

Use standard load balancer names

SYNOPSIS

Load balancer names should use a standard prefix.

DESCRIPTION

An effective naming convention allows operators to quickly identify resource type, associated workload, deployment environment and Azure region.

For load balancers, the Cloud Adoption Framework recommends using the lbi-, and lbe- prefix. Use of different prefixes depends on the intended usage of the load balancer.

Requirements for load balancers names:

  • At least 1 character, but no more than 80.
  • Can include alphanumeric, underscore, hyphen, period characters.
  • Can only start with a letter or number, and end with a letter, number or underscore.
  • Load balancer names must be unique within a resource group.

RECOMMENDATION

Consider creating load balancers with a standard name. Additionally consider using Azure Policy to only permit creation using a standard naming convention.

NOTES

This rule does not check if load balancer names are unique.

To configure this rule:

  • Override the CAF_LoadBalancerPrefix configuration value with an array of allowed prefixes.
  • Override CAF_UseLowerNames with false to allow mixed case in resource names. By default only lower-case letters and other supported characters are allowed. This option affects all resource name rules.
