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. |
