Cost optimization and IP addresses

IP services are a collection of IP address-related services that enable communication in an Azure Virtual Network. Public and private IP addresses are used in Azure for communication between resources. The communication with resources can occur in a private Azure Virtual Network and the public internet.

Key features include:

• Public IP addresses
• Public IP address prefixes
• Private IP addresses
• Routing preference
• Routing preference unmetered

For more information, reference What is Azure Virtual Network IP Services?

To understand how IP services support a cost-optimized workload, reference the following articles:

• IP addresses pricing
• Create, change, or delete an Azure public IP address
• Routing over public Internet (ISP network)

Checklist

Have you configured IP addresses with cost optimization in mind?

• PIPs (Public IPs) are free until used. Static PIPs are paid even when not assigned to resources.

Configuration recommendations

Consider the following recommendation for cost optimization when configuring IP addresses:

Recommendation	Description
PIPs (Public IPs) are free until used. Static PIPs are paid even when not assigned to resources.	There's a difference in billing for regular and static public IP addresses. Develop a process to look for orphan network interface cards (NICs) and PIPs that aren't being used in production and non-production.
