Upgrading a basic public IP address to Standard SKU - Guidance
In this article, we'll discuss guidance for upgrading your Basic SKU public IPs to Standard SKU. Standard public IPs are recommended for all production instances and provide many key differences to your infrastructure.
Steps to complete the upgrade
We recommend the following approach to upgrade to Standard SKU public IP addresses.
- Learn about some of the key differences between Basic SKU public IP and Standard SKU public IP.
- Identify the Basic SKU public IP to upgrade.
- Determine if you would need Zone Redundancy.
- If you need a zone redundant public IP address, create a new Standard SKU public IP address using Portal, PowerShell, CLI, or ARM template.
- If you do not need a zone redundant public IP address, use the following upgrade options.
- Create a migration plan for planned downtime.
- Depending on the resource associated with your Basic SKU public IP addresses, perform the upgrade based on the following table:
|Resource using Basic SKU public IP addresses||Decision path|
|Virtual Machine or Virtual Machine Scale Sets (flex model)||Disassociate IP(s) and utilize the upgrade options detailed after the table.|
|Load Balancer (Basic SKU)||New LB SKU required. Use the upgrade scripts for virtual machines or Virtual Machine Scale Sets (without IPs per VM) to upgrade to Standard Load Balancer|
|VPN Gateway (Basic SKU or VpnGw1-5 SKU using Basic IPs)||New VPN Gateway SKU required. Create a new Virtual Network Gateway with a Standard SKU IP.|
|ExpressRoute Gateway (using Basic IPs)||New ExpressRoute Gateway required. Create a new ExpressRoute Gateway with a Standard SKU IP.|
|Application Gateway (v1 SKU)||New AppGW SKU required. Use this migration script to migrate from v1 to v2.|
If you have a virtual machine scale set (uniform model) with public IP configurations per instance, note these are not Public IP resources and as such cannot be upgraded; a new virtual machine scale set is required. You can use the SKU property to specify that Standard IP configurations are required for each VMSS instance as shown here.
Basic SKU vs. Standard SKU
This section lists out some key differences between these two SKUs.
|""||Standard SKU public IP||Basic SKU public IP|
|Allocation method||Static.||For IPv4: Dynamic or Static; For IPv6: Dynamic.|
|Security||Secure by default model and be closed to inbound traffic when used as a frontend. Allow traffic with network security group is required (for example, on the NIC of a virtual machine with a Standard SKU public IP attached).||Open by default. Network security groups are recommended but optional for restricting inbound or outbound traffic.|
|Availability zones||Supported. Standard IPs can be non-zonal, zonal, or zone-redundant. Zone redundant IPs can only be created in regions where three availability zones are live. IPs created before zones are live won't be zone redundant.||Not supported|
|Routing preference||Supported to enable more granular control of how traffic is routed between Azure and the Internet.||Not supported.|
|Global tier||Supported via cross-region load balancers||Not supported|
|Standard Load Balancer Support||Both IPv4 and IPv6 are supported||Not supported|
|NAT Gateway Support||IPv4 is supported||Not supported|
|Azure Firewall Support||IPv4 is supported||Not supported|
Upgrade using Portal, PowerShell, and Azure CLI
Use the Azure portal, Azure PowerShell, or Azure CLI to help upgrade from Basic to Standard SKU.
- Upgrade a public IP address - Azure portal
- Upgrade a public IP address - Azure PowerShell
- Upgrade a public IP address - Azure CLI
