Focused on reworking interface and ecosystem while load balancing has improved uptime

A10 Networks Thunder ADC is quite solid, but there are some issues that I face, particularly with the user interface. A current issue is that the GUI is less polished than competitors. When compared against F5 BIG-IP or Citrix ADC, the GUI is not as good. The documentation and learning curve are areas that can be improved by A10 Networks. Compared with larger vendors including F5, Cisco, or Palo Alto, A10 has a smaller ecosystem. Although A10 Networks Thunder ADC supports cloud and Kubernetes, many enterprises now expect deeper cloud-native functionality. Improvement areas include Kubernetes Ingress maturity, service mesh integration, and auto-scaling intelligence.

Quotes from Members

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

Pros

"The most valuable features in A10 Networks Thunder ADC are the ease of configuration, user-friendliness, and simplicity to sell to customers."

"The Global Server Load Balancing (GSLB) is simple to use."

"It has provided improvement in regards to flexibility of our applications between data centers."

"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."

"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."

"It is very useful to have a simple dashboard where you can login and look into what your traffic patterns are, then look and see what times of day you're experiencing the heaviest traffic. You can quickly identify if you are possibly having a security issue or security breach. It makes it very easy to use the box."

"A10 Networks Thunder ADC is a very natural solution in the industry; when compared to the other vendors, it's easier to use, more user-friendly, and more mature."

More A10 Networks Thunder ADC pros

"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 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 Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."

"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."

"The price is very good, and it's not very expensive."

Cons

"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."

"In future updates, I would like to see better speed in the features of A10 Networks Thunder ADC."

"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."

"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."

"However, the future might not be bright for this company, and I highly suggest that existing and potential users follow the progress of their legal battle with Brocade."

"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."

"There is two-factor authentication built-in, but it could be more robust."

"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."

More A10 Networks Thunder ADC cons

"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."

"The quality of the solution's performance could be improved."

"We find with WAN optimization it’s a bit unstable but we don't use it for that."

"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."

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."

"It is $7000 per unit for the support annually."

"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."

"You get a lot more for your dollar with A10."

"One of the main reasons for switching away from Cisco was the licensing model. A10 gives you global server load balancing for free, while Cisco charged a significant licensing fee for that."

"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."

"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."

More A10 Networks Thunder ADC 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."
