Application delivery has improved and security now ensures reliable high‑traffic e‑commerce

A10 Networks Thunder ADC offers several strong features that make it a very competitive solution. First, they provide advanced Layer 4 or Layer 7 load balancing. Another key feature is SSL offloading and encryption handling. A10 Networks Thunder ADC is also highly scalable and flexible. Scalability for A10 Networks Thunder ADC shows up in my day-to-day operations during high-traffic events such as Black Friday. One feature I find really powerful and something underrated about A10 Networks Thunder ADC is A-Flex. 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. A10 Networks Thunder ADC has a significant impact on my organization in several ways. First, it improves application availability and performance. From a security perspective, it helps protect applications against threats such as DDoS attacks. It also has a strong operational impact. In terms of cost, it can lower both CapEx and OpEx.

Quotes from Members

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

Pros

"A10’s ADCs is a solid, high-performance platform."

"The scalability is really good; you can easily unify many devices at once, ADCs are simple to configure and each device is powerful, and we have two engineers managing and monitoring multiple systems and it works well for us."

"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."

"Overall, A10 ADC is pretty good, it's reasonably priced and easy to use."

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

"A10 Networks Thunder ADC fits quite seamlessly into my overall workflow, and once it is set up, it became more of a set-it-and-monitor-it, autopilot mode component rather than something I constantly have to tweak."

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

"The support we receive from the team is quite excellent, and nothing directly comes to mind regarding improvements for A10 Networks Thunder ADC at the moment."

More A10 Networks Thunder ADC pros

"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."

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

"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."

More Barracuda Load Balancer ADC pros

Cons

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

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

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

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

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

"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."

"There are competitors that have more features."

"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."

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."

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

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

"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."

More Barracuda Load Balancer ADC cons

Pricing and Cost Advice

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

"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."

"The price is good they are very comparative."

"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 price of A10 Networks Thunder ADC depends on capacity and the customer's requirement. They have several offerings. They have different price models and options to choose from. Additionally, you need to subscribe to support for the hardware appliances."

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

"The solution costs less than its competitors."

"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."
