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. For more information on load balancing, see the Load Balancing For Clustered Barracuda CloudGen WAF Instances in the Old Microsoft Azure Management Portal article.

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.

If you need to add additional storage, you must create a new attached drive; this applies to Barracuda virtual machines purchased through the Microsoft Azure Marketplace February 2015 or later. You cannot attach new storage in earlier deployments
