Comparison between Azure Application Gateway V1 and V2

Microsoft has announced new version of Azure Application Gateway and its Web Application Firewall module (WAF). In this article, we will discuss about the enhancements and new highlights that are available in the new SKUs i.e. Standard_v2 and WAF_v2. Enhancements and new features: Scalability: It allows you to perform scaling of the number of instances on the traffic. Static VIP: The VIP assigned to the Application Gateway can be static which will not change over its lifecycle. Header Rewrite: It allows you to add, remove or update HTTP request and response headers on application gateway. Zone redundancy: It enables application gateway to survive zonal failures which allows increasing the resilience of applications. Improved Performance: Improvement in performance during the provisioning and during the configuration update activities. Cost: V2 SKU may work out to be overall cheaper for you relative to V1 SKU.
