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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The initial setup was straightforward and deployment took one day."
"The price is very good, and it's not very expensive."
"The solution is simple and powerful. I find the Barracuda Load Balancer ADC's load balancing function most valuable. It balances the traffic well. The security features, like the Web Application Firewall, are also very helpful."
"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."
"The Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."
"The solution integrates different applications and APIs securely, enhancing overall security and network optimization."
"The solution is easy to set up."
"It has a filter available, although we are not currently using it because it is not part of our requirements. But it is a good option and when it becomes part of our requirements we will definitely use it."
"Microsoft Azure Application Gateway impacts our cost savings while maintaining higher performance."
"The simplicity of the solution and its ability to integrate easily with others are its most valuable aspects."
"The solution has built-in rules that reduce alerts and are easy to configure."
"Good customization; able to report and take action on alerts."
"The most valuable feature is WAF."
 

Cons

"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."
"The quality of the solution's performance could be improved."
"We find with WAN optimization it’s a bit unstable but we don't use it for that."
"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."
"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."
"We have encountered some issues with automatic redirection and cancellation, leading to 502 and 504 gateway errors. So, I experienced some trouble with containers."
"The solution should provide more security for certificate-based services so that we can implement more security on that."
"The configuration is very specific right now and needs to be much more flexible."
"In future releases of Microsoft Azure Application Gateway, I would to see more AI functionalities and a better dashboard as well as some customizations."
"It could be more stable, and support could be better. It would also be better if they offered more features. For example, it lacks security features. Before we used another English solution, and we realized that some of the rules were not set up correctly and passed through the Application Gateway's English controllers. But the problem, in this case, is if you send ten rules, for example, six rules hit some issues. IP address blocking could be better. The rules, for example, don't work properly. If you have one issue, one rule or another rule will not work. This sounds like total madness to me."
"It is a bit tricky to configure. You've got to have a very specific format to configure it. They should make it a little bit easier to configure. Mapping the certificates into it isn't easy, and it could be better. Currently, you've to write a bit of automation to pull certificates directly to HTTPS."
"The increased security that we are considering is because of some of the things that the security team has brought to our attention. They have pointed out that we would most likely require a better web application firewall than Azure Application Gateway."
"The tool's pricing could be improved."
 

Pricing and Cost Advice

"I rate the solution's pricing a five out of ten."
"Load Balancer ADC is cost-effective and is about half the price of F5."
"Every solution comes with a license and cost. Microsoft provides the license and the total cost is for the maintenance every year."
"It is an expensive solution. We have an enterprise agreement, it is monthly."
"Between v1 and v2, there is a lot of change in the pricing. It is very costly compared to AWS."
"I rate the pricing seven out of ten because some third-party solutions are even costlier than this."
"It is not expensive."
"Microsoft Azure Application Gateway is expensive."
"We use the tool's basic subscription. Its licensing costs are monthly."
"The solution is reasonably priced."
