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

"Compared to F5, which I used about six years ago, the A10 is much easier when routing. You don't have to use the wildcard bits to route it between the different segments. It's much less troublesome to configure."

"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."

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

"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."

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

"The ADCs are pretty straightforward and easy to use, with a GUI where you can see everything and a CLI where you can use a command to get the information that you want very fast."

"The ease of use is very good. It's very robust. It just sits and works."

"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."

More A10 Networks Thunder ADC pros

"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."

"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."

"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."

Cons

"A graphical dashboard for analyzing performance is needed."

"The user interface is what people complain about most of the time, particularly if they don't use it very often. Then they complain that it's a bit clunky."

"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 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."

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

"The setup depends on certain situations. In certain scenarios, it may be more complex than others."

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

"There is room for improvement in the GUI. The 2.7 software train 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."

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."

"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."

"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

"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."

"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."

"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."

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

"The solution costs less than its competitors."

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

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

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

More A10 Networks Thunder ADC pricing and cost advice

"Load Balancer ADC is cost-effective and is about half the price of F5."

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