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

"Being a public entity and having a public website which is highly visible with a lot of traffic, we are a target for DDoS. Within the last year, we have had a couple of DDoS attacks which could have affected our web traffic and taken down certain parts of our website. This did not happen because the A10 was able to mitigate the attacks using rate limiting that can be configured for DDoS mitigation on the box."

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

"It's a phenomenal investment that the company has made, improving our performance and management and saving us money."

"The SLB and GSLB load balancing are the most valuable features. They meet our need to do server-side load balancing and global site load balancing so we can distribute traffic, not only intra-data center, but inter-data center."

"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."

"We can control access based on the specific application. If other devices are attempting to directly access the servers, you can block them. Additionally, you can balance the load among servers to optimize performance. For example, utilizing caching can make the application run faster."

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

"It solved the CGNAT performance issues and, within two years, it had no problems and no outages."

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 initial setup was straightforward and deployment took one day."

"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."

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

"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."

Cons

"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."

"A10 Networks Thunder ADC is quite solid, but there are some issues that I face, particularly with the user interface."

"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 interface and integrated custom applications can be a bit difficult."

"While I do use the security features on the load balancing, I find them to be primitive."

"The solution should add automation features in the next release."

"The tool's load-balancing feature should improve."

More A10 Networks Thunder ADC cons

"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."

"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 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 a third of the price of the F5 competition."

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

"The price is good they are very comparative."

"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."

"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."

"There were budgetary constraints that keep us from investing in the single pane of glass traffic management feature. We saw a demo of this feature about a year to a year and a half ago."

"We previously had F5 and switched because of costs."

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."
