Global load balancing has improved reliability and currently reduces latency across multi-cloud

I have experience with AWS, and I also have experience with both AWS and Azure, and sometimes GCP as well. We utilize multi-cloud support with A10 Networks Thunder ADC. We have customers utilizing A10 Networks Thunder ADC in the public cloud as well. I didn't technically involve myself with analytics in A10 Networks Thunder ADC because I haven't been involved in that part in the past few years. According to my team, the analytics tools are quite prominent, so there are no issues there. We have a distributorship with A10 Networks and are considered a partner. I would rate this review 9 out of 10.

Quotes from Members

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

Pros

"With A10, we have a very robust load balancing solution that is capable, like F5, of iRule or aFleX scripting."

"The Deterministic CGNAT feature is valuable for us."

"For the past two and a half years, we have not had a need to open a tech support ticket. It is really stable. In the past, our experience with tech support was that they were extremely helpful."

"A10 explained why the latency dropped significantly on a site that we have."

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

"The solution is stable."

"A10 Networks Thunder ADC is an easy-to-use and flexible solution."

"If you want a reliable solution that is very easy to configure and administrate, the A10 is the right choice."

More A10 Networks Thunder ADC pros

"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."

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

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

"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."

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

"The initial setup was straightforward and deployment took one day."

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

Cons

"The user interface is not as pretty as it could be."

"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."

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

"It scaled well for our numbers, up to 3 million subscribers for our most crowded region but I would like to see the same scalability numbers for the virtualized version as well."

"The primary problem with A10 Thunder devices is the documentation and the knowledge base. This causes us to spend much more time conducting research and testing, which is the worst case that we have experienced."

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

"It's not easy to use (mediocre at best). It's difficult for administrators to maneuver through the web user interface."

"Maybe one concrete thing that they can improve on is their two-factor authentication."

More A10 Networks Thunder ADC cons

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

"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

"We just pay for support in addition to our licensing."

"The price of the maintenance support is too expensive."

"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."

"Pricing is one of the features of the product that influence customers to use the product."

"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."

"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 price is good they are very comparative."

"I rate the solution's pricing a five out of ten."
