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."
"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."
"The price is very good, and it's not very expensive."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
"The Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."
"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."
"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."
"The most valuable feature of Microsoft Azure Application Gateway is its ease of use."
"This product works well to secure my public facing websites from things like sql injections"
"Good customization; able to report and take action on alerts."
"The solution has built-in rules that reduce alerts and are easy to configure."
"I like the tool's stability and performance."
"Application Gateway automatically redirects unwanted users and takes care of the security aspect. It also handles the performance side of things, which is why we use it."
"It is a scalable solution...The installation phase of Microsoft Azure Application Gateway is very easy."
"Some of the key features of this solution are the low-level maintenance required, floating proxy service, and load balancing."
 

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."
"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."
"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."
"We find with WAN optimization it’s a bit unstable but we don't use it for that."
"The quality of the solution's performance could be improved."
"Scalability can be an issue."
"The solution doesn’t support wildcard-based and regular expression-based rules."
"I believe that there is room for improvement in terms of additional functionality. It is an advantage to have features readily available for configuration without needing customer-defined rules."
"It takes a lot of time for a certificate to update in the system. That is a huge drawback, affecting the load-balancing side. And when there are changes to the load balancing, it affects the end-user."
"The solution has many limitations. You cannot upgrade the VPN to the application gateway. So I started with version one, which has limited capabilities, and they provided version two. And unfortunately, I cannot upgrade from v one to v two like other services. So I have to decommission the version one and create a new one with version two. Also the version one was complex with the certificates uploading the SQL certificates."
"In the next release, the solution could improve the integration with Service Mesh and other Azure Security Services."
"The support can be improved when you are configuring the system rules. The Disaster Recovery feature can be added in the next release. The price of the solution can be reduced a bit."
"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."
 

Pricing and Cost Advice

"Load Balancer ADC is cost-effective and is about half the price of F5."
"I rate the solution's pricing a five out of ten."
"I rate the price of Microsoft Azure Application Gateway an eight out of ten."
"The product is expensive. I rate the pricing a seven out of ten."
"I rate the pricing seven out of ten because some third-party solutions are even costlier than this."
"Microsoft Azure Application Gateway is expensive."
"The solution is reasonably priced compared to other solutions."
"I would rate the pricing a three out of ten, with ten being cheap and one being expensive."
"The solution's pricing is not complex. It is not expensive from our point of view."
"We use the tool's basic subscription. Its licensing costs are monthly."
