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…

Identifying compromised traffic and securing data has been a significant advantage
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.

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

"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."
"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."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
"I think F5's tech support may be better than Citrix's because they mainly focus on the ADC product, but Citrix support covers Hypervisor, XenMobile, FAS, and ADC. And from my experience, sometimes, we face some issues that Citrix cannot handle."
"The most valuable feature is the F5 LTM (Local Traffic Manager). This is the part of the product most organisations will be using most. It provides the core functionality to be able to load balance services and the means and the intelligence to be able to load balance based on advanced logic, e.g., TCL scripting."
"ASM for WAF."
"LTM's most valuable features include application security, data collection, and parameter-level rules."
"F5 Big-IP Local Traffic Manager has better modular features especially LTM, which according to the clients, is very beneficial. Most of the users opt for a combination of big IP LTM and WAF which helps them to leverage application load balancing and enhance application security many-fold."
"LTM."
"We always use technical support and the team helps us very well. They're able to effectively find and fix issues and they respond very quickly."
"iRule feature is useful."
"High availability, performance, and security are the main pillars. It enhances the security for accessing the applications."
"What I like most about Citrix NetScaler is its stability, and I didn't see a lot of issues with it."
"The solution is very stable."
"SSL Offload"
"I found that the GUI was very easy to to navigate. If you were looking for something, it was fairly easy to find. There's a lot of third-party documentation and information available online as well."
"I prefer this solution because of its user-friendly interface. I find it simple and close to what I am currently using, which is Citrix Fortiva Access for Multi-Factor Authentication. I appreciate the familiar user interface and troubleshooting tools it offers."
"Load Balancing and SSL offloading are key features."
"My clients use it for load balancing."
 

Cons

"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."
"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."
"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."
"A more hybrid approach would be beneficial for users."
"They need to develop the reporting tools further."
"LTM's cloud capabilities could be improved. Cloud providers all offer load balancing, but you can't get the same level of security. F5's cloud service is still not on par with its on-prem service."
"A more intuitive interface would be helpful."
"The ASM administration is quite complex. The topic itself is pretty complex, so it is not easy to provide a nice, clean interface. There are a lot of references and dependencies in-between the different subareas."
"If one virtual portion is unavailable, it can cause issues."
"Cloud native integration should be provided."
"Not everything is intuitive."
"There is room for improvement regarding the pricing policy for Citrix offices."
"Citrix should offer a demo or free-trial version of NetScaler. Several other vendors do, but Citrix does not. Pricing should also be more readily available."
"Their upgrades are not very backward compatible, and sometimes they mess up."
"It can be difficult to setup."
"The configuration for its web application firewall is complicated."
"We are looking for some in-depth monitoring and analytics and more information that Citrix Director doesn't provide. ControlUp has insights that not only give you an overview but also allow you to do some drill-down troubleshooting for what's going on in your environment. We are looking for some more analytical and monitoring data to be able to monitor the environment better, not only from an application standpoint but also from the standpoint of the infrastructure to everything it sits on. They can provide more data to the administrators about what's going on within the application. They can provide data not only on the application side but also about what the application sits on. They're making strides with Citrix Analytics in regards to that."
"Citrix should improve the documentation. It is not really clear how to set up many features to our advantage. When we setup Citrix NetScaler ADC, we have to figure it out by ourselves without a lot of documentation."
"The WAF component needs to be simplified so that it is easier to use."
 

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."
"This solution comes with a standard license, and there are also extra licenses that can be obtained. The licenses are purchasable for durations of one, two, three, and five years. The hardware is something to consider when purchasing"
"If your IT budget is good, go for it."
"Purchasing through the AWS Marketplace was very simple. The main reason that we went this way was the simplicity of buying it there. It is maintained and upgraded for us, and this makes it easy to stay current."
"In my view, the cost is somewhat on the higher side. There are discounts available, but I wouldn't say it's overpriced. It's not cheap either, and the value for money is a bit higher from that perspective."
"The price is little bit on higher side compared to the cost of NGINX."
"We purchased through the AWS Marketplace because it was a popular way to go, and we were intrigued. The price of this product is not an issue. They have good pricing and licensing."
"The price of F5 BIG-IP LTM could improve."
"Great product for the money. But they can get really expensive, so get what meets your needs."
"We have a yearly licencing fee, and there are no additional costs."
"Its price is comparable to others and affordable."
"For partners, NetScaler is not as expensive price-wise versus F5."
"The pricing could be lower."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
"Citrix ADC could improve the price and make it less expensive, other competitors have a better prices. This would allow Citrix ADC to keep dominating the market."
"I rate the pricing an eight out of ten since it is expensive."
"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"
