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."

"Beyond the standard ADC feature, what really stands out to me about A10 Networks Thunder ADC is how customizable, performant, and automated the platform is."

"The advanced load balancing plus SSL offloading in A10 Networks Thunder ADC directly improves application uptime, speed, scalability, server efficiency, and user experience."

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

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

"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."

"The ease of use is very good, it's very robust, and it just sits and works so well that we forget that it's there a lot of the time."

"The solution is flexible."

More A10 Networks Thunder ADC pros

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

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

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

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

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

Cons

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

"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."

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

"DDoS protection is one kind of extra feature in A10 Networks Thunder ADC solution, but I see that in the inbuilt solution, the data classification part is pending there, creating a gap between the DDoS and the data classification parts."

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

"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."

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

"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."

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."

"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."

"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."

Pricing and Cost Advice

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

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

"We did try out the solution’s Harmony analytics and visibility controller for its one-year trial. Due to the cost, we chose not to keep it onsite."

"The pricing is a third of the price of the F5 competition."

"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."

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

"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."

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."
