Cloud hosted deployment of the Barracuda CloudGen WAF for Azure currently supports One-Arm Proxy Mode. For more information, see Configuring One-Arm Proxy Mode.
To meet a variety of performance requirements, the A1, A2, A3 and A4 instance types are supported. Depending on the instance type, you can have:
- Up to 8 vCPU.
- Up to 14 GB of memory.
The Barracuda CloudGen WAF for Azure is available with the Bring Your Own License (BYOL) and Hourly / Metered option.
Bring Your Own License (BYOL)
With the Bring Your Own License (BYOL) option, you are required to get the Barracuda CloudGen WAF license token, either by:
- Providing the required information for a free evaluation at https://www.barracuda.com/purchase/evaluation OR
- Purchasing online at https://www.barracuda.com/purchase.
With this license option, there will be no Barracuda CloudGen WAF Software charges, but Microsoft Azure usage charges on Microsoft will be applicable.
BYOL Models and Instance Types
For BYOL, Barracuda Networks offers four models. The table below lists each model and the number of cores supported.
If you want to increase the performance of a license that you have already purchased, you can buy a license with more cores from Barracuda Networks and reconfigure your instance.

You can add multiple Barracuda CloudGen WAF instances under one cloud service and load balance the traffic between the deployed instances to increase the throughput.

Pay As You Go (PAYG)
With the Pay As You Go (PAYG) licensing option, you complete the purchase or evaluation of the Barracuda CloudGen WAF entirely within the Microsoft Azure gallery. After the instance is launched, it is provisioned automatically. You are charged hourly for both the Barracuda CloudGen WAF Software and Microsoft Azure usage on Microsoft.
PAYG Model and Instance Types
For more information on supported instance types, Default vCPU, Default Memory and Hourly pricing, refer to Barracuda Web Application Firewall Pricing Details.
If you want to increase the performance of an existing VM, configure it with a larger instance type on Microsoft Azure and you will be charged accordingly by Microsoft. The VM will automatically be reconfigured by Microsoft with the resources and capabilities of the larger instance type.
