Protects connection and servers from direct access with control access feature
The initial setup is very simple. The issue is that it achieves high output across all its features, specifically the output ports. This affects the customer's solution because sometimes, the customer is even aware of the user's activity on certain servers. If you have all the necessary information, we can quickly deploy the solution within two to three days. The size of the Thunder ADC depends on its configuration. For example, the cache converter typically includes more than two rack units, often requiring at least three rack units for adequate space. I rate it a ten out of ten, where one is difficult, and ten is easy.

A simple and powerful solution with WAF feature
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 use the SSL offloading feature too. It's very helpful because it prevents overload. Our application runs on HTTP, but we upload HTTPS on the load balancer. This means there are no performance issues. I think it's very helpful.

Quotes from Members

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

Pros

"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"The DNS application firewall and load balancing are very valuable."
"The Global Server Load Balancing (GSLB) is simple to use."
"The solution is flexible."
"The most valuable features in A10 Networks Thunder ADC are the ease of configuration, user-friendliness, and simplicity to sell to customers."
"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."
"Compared to F5, which I used about six years ago, the A10 is much easier when routing. You don't have to use the wildcard bits to route it between the different segments. It's much less troublesome to configure."
"It helps with the efficiency of application deployments and data security."
"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 price is very good, and it's not very expensive."
"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."
"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."
 

Cons

"The solution does logging, but the logging capacity is really small. Because we have a bunch of traffic here, we usually get a logging-side warning that "This many logs were lost because of the heavy traffic." If the logging was better, that would be very good."
"I would like them to provide learning tips and a community forum where users can share ideas. They need more detailed support articles on the A10 website."
"Traffic flow issues are very difficult, as there's no means for us to analyze the traffic coming in or out of the appliance without technical support."
"The costs can be quite high."
"Currently, the solution's WAF features are fewer. They should consider increasing their WAF features."
"The interface and integrated custom applications can be a bit difficult."
"There is room for improvement in the GUI. I just migrated from the 2.7 software train to the 4.1, and there are still people on 2.7. The latter is a very old GUI if you compare it to F5. It's not as easy to use and a lot of things are missing. They've made a lot of improvements in the 4.1 step, but compared to the ease of use of F5, it's still quite difficult. For people who haven't got a lot of experience, the GUI can be quite challenging."
"The solution should add automation features in the next release."
"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."
"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."
"The quality of the solution's performance could be improved."
 

Pricing and Cost Advice

"It is $7000 per unit for the support annually."
"The price of A10 Networks Thunder ADC depends on capacity and the customer's requirement. They have several offerings. They have different price models and options to choose from. Additionally, you need to subscribe to support for the hardware appliances."
"The price of the maintenance support is too expensive."
"For the hardware and license, we paid $35,000 per box, which was a one-time cost. Then, for the Gold Support on the two boxes, we pay $9400 annually."
"We just pay for support in addition to our licensing."
"The solution costs less than its competitors."
"The pricing is a third of the price of the F5 competition."
"As for the initial investment in the hardware, F5 and A10 are quite similar now. For the current A10 solution, the initial cost was about $36,000. As for annual support, the F5 solution would be between $10,000 and $12,000, while the A10 is $2,200 a year for support."
"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."
