Balances loads efficiently and saves costs but could improve initial setup
The typical use case for Barracuda Load Balancer ADC involves managing and distributing network traffic efficiently to maintain system performance. Clients use Barracuda Load Balancer ADC for its ability to handle and balance loads across servers I have seen improvements in Barracuda Load…

Mutual TLS has secured our web services and now needs broader protocol support
The most valuable feature we have found in Microsoft Azure Application Gateway is mutual TLS. We find mutual TLS valuable because we can verify the client securely by setting up the trust certificate of the client, and also if we do it at the client side as well. This successfully develops mutual trust, ensuring that we know the client who is calling our service is a legitimate client. That is a very nice feature.Microsoft Azure Application Gateway has helped manage our traffic efficiently because we have many web services that we can put behind the same URL, and we can have different URLs with the same Application Gateway with a limited number of listeners. We can do host-based routing as well as URL-based routing or path-based routing. It supports both, so we can have even a single URL supporting many applications, or we can have different URLs for different applications respectively. We have both use cases.

Pros

"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."

"It does an excellent job of load balancing."
"The solution's integration is very good."
"We use the product in front-end and back-end applications to do the load balancing smartly."
"The tool is easy to use and quite flexible. It has policy management features as well. The solution screens all traffic to our web applications before passing it to the application. We recently tested it on one of our poorly developed applications, and the upgrade gave us a 100% result based on our tests. It's very effective as a security measure, and people can detect threats even through the web application."
"In my experience, Microsoft products have a smooth integration and facilitate easy management and monitoring. Using Azure Application Gateway allows us to efficiently handle the system loads."
"I find Application Gateway’s WAF module valuable because it helps prevent layer 7 attacks."
 

Cons

"The Barracuda Load Balancer ADC could be improved with more customization features. For example, F5 uses iRules for custom configurations. I haven't found something similar in Barracuda yet. The load balancer and WAF's basic and common features are enough, but we need more customization options."
"The quality of the solution's performance could be improved."
"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."

"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."
"The tool's pricing could be improved."
"Microsoft Azure Application Gateway could improve by allowing features to use more third-party tools."
"Overall, I would rate Microsoft Azure Application Gateway seven out of ten. It can be improved; for example, one feature I mentioned is the support for non-HTTPS protocols such as TCP, which could allow one endpoint for all kinds of protocols."
"We faced some downtime while validating CNAME."
"The solution doesn’t support wildcard-based and regular expression-based rules."
"There is room for improvement in the pricing model."
"In the next release, the solution could improve the integration with Service Mesh and other Azure Security Services."
