Quotes from Members

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

Pros

"A10 Networks Thunder ADC is an easy-to-use and flexible solution."
"The ADCs are pretty straightforward and easy to use. There is a GUI base where you can go in and see everything, but they also have a CLI base where you can use a command and get the information that you want, very fast."
"We have two appliances and I'm able to move my application from one appliance to another. I don't have to move my whole A10 to be active on the other side or to be passive on the other side. If an application is having a problem, I can just move it using a command."
"The Global Server Load Balancing (GSLB) is simple to use."
"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."
"We do have the option of creating virtual chassis, so that gives it a bit more security. If we find an application which is not going to play well in the main pool, we can easily create a virtual chassis and have that application in that virtual chassis. With the virtual chassis we can also create system partitions and have a test system for test applications, and have the others elsewhere."
"The solution is flexible."
"The DNS application firewall and load balancing are very valuable."
"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."
"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."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
 

Cons

"A10 Networks Thunder ADC could improve on the Application Delivery Controller. it's not a fully-fledged web application firewall solution. For example, application data and support need to improve."
"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."
"They need to make the user interface (GUI) a bit more usable and intuitive. Some features can be a little difficult to find at times. Sometimes, the workflow in the GUI doesn't match the workflow of an actual workflow. E.g., if I want to create a load balancer application, sometimes you've got to do things a bit out of order in the GUI in order to make it work right."
"In my opinion, they need to improve their cloud support. There is support for cloud, but not all functions are there, such as high-availability."
"The tool's load-balancing feature should improve."
"The user interface is not as pretty as it could be."
"The setup depends on certain situations. In certain scenarios, it may be more complex than others. For example, while the initial configuration may be easy, the environment itself may be complex and that may limit the ease of deployment. It is easy for those who understand their environment."
"We are starting to do a lot with containers and how the solution hooks into Kubernetes that we haven't explored. I'm hoping that they have a lot of hooks into Kubernetes. That would be the part for improvement: Marketing use cases with containers."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The pricing is fine, considering the features they are providing. If you are an individual user, they'll price the product differently compared to how they price the product that is sold to an organization."
"The solution costs less than its competitors."
"You get a lot more for your dollar with A10."
"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."
"We just pay for support in addition to our licensing."
"We previously had F5 and switched because of costs."
"Pricing is one of the features of the product that influence customers to use the product."
"The price of the maintenance support is too expensive."
"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."
