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

"You get a lot more for your dollar with A10."

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

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

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

"The most valuable features in A10 Networks Thunder ADC are the ease of configuration, user-friendliness, and simplicity to sell to customers."

"A lot of our SSL management is done on the front-end side, so there is one pane of glass for a lot of our security certificates. It gives us visibility. It also falls under when certificates are going to expire. Even for servers that are coming down, we can see how that affects the traffic flow by using the services map."

"For example, it is easy to use, easy to integrate, or the product helps save time."

More A10 Networks Thunder ADC pros

"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."

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

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

"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."

Cons

"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."

"The product is expensive."

"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 solution does logging, but the logging capacity is really small."

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

"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."

"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."

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

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."

"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."

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

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."

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

"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."

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

"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."

"The solution costs less than its competitors."

"You get a lot more for your dollar with A10."

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."
