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…

Offers better visibility into user sessions compared to other solutions
Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.

Quotes from Members

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

Pros

"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 price is very good, and it's not very expensive."
"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."
"The Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."
"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."
"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."
"Global load balancing between data centers."
"If you need PCI-compliance and have high security requirements, WAF is the most valuable feature. If you need to monitor your load-balancing services with complex types of monitoring, make sure everything is alright, and load balancing is important, Content Switching and Monitoring features are the keys to your needs. If you want to provide a lot of static images or data, the Caching feature works best for you."
"The web application firewalling component is a powerful feature."
"My clients use it for load balancing."
"Load Balancing and SSL offloading are key features."
"Citrix Web App API Protection allows you to enable a blocking mode"
"In comparison to F5 BIG-IP, this is the best solution."
"The most valuable feature is the SSL VPN."
 

Cons

"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."
"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."
"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 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."
"Sometimes when I enable NetScaler, it makes the box crash randomly."
"Technical support could be improved."
"The technical support could be better. Whenever I contacted support, I rarely got the solution that we needed. And most of the time, I finished fixing the problem by looking on the internet or by finding documents about the problem on Google."
"The solution should be able to scale more effectively than it does."
"The solution has too many bugs in the software and it's always difficult when you need to update."
"I think the documentation should be improved - there should be more documentation."
"I would like to see support for scripting, like "iRule", which gives you the option to implement any configuration which is not available out of the box."
"There are specific features that we like but are not available at our licensing level."
 

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."
"I give the price of the solution a seven out of ten."
"You get the value for your money. There aren't any hidden fees."
"NetScaler does the same thing as an F5 and it's cheaper."
"I rate the tool's pricing an eight out of ten."
"We have all the features and functions of Citrix because we have a premium license."
"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
"F5 BIG-IP is much more expensive than Citrix ADC. For example, If we choose two platforms, Citrix ADC, 3000 version, and we choose F5, F4200 version. F5 BIG-IP has connections, timers, and throughput similar to Citrix ADC, but the price is very expensive."
"It all depends on the features that will be used and the number of accesses."
