Load balancing has improved uptime and now keeps peak e-commerce traffic running smoothly

  • April 19, 2026
  • Review from a verified AWS customer

What is our primary use case?

I primarily use A10 Networks Thunder ADC for load balancing and application delivery across my production environments, sitting in front of my critical web and API services that help solve problems by distributing traffic efficiently and maintaining uptime during peak loads. A significant part of the use case is ensuring high availability and minimizing downtime during maintenance or unexpected spikes whenever there is more traffic or a network issue. One of the main cases is also a combination of application delivery and basic security handling, using A10 Networks Thunder ADC to manage traffic across multiple application servers while leveraging features such as DDoS protection and SSL offloading. Whenever major traffic occurs, I use this to run it efficiently in a hybrid environment where some workloads are on-premises and others are in the cloud.

I use A10 Networks Thunder ADC mainly in front of my e-commerce platform that I have built for a client, and during seasonal sales, I saw traffic spikes at around three to four times the normal load that I was receiving on that site. A10 Networks Thunder ADC distributes the traffic across multiple backend servers and handles SSL offloading, which keeps response times stable, and without it, my app servers would have become overwhelmed very quickly.

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. Most of my interaction is around policy updates or scaling decisions rather than day-to-day firefighting and working hard, shifting me to working smartly rather than hard.

What is most valuable?

The standout features in A10 Networks Thunder ADC are definitely its load balancing capability and SSL offloading because these are very crucial and primary features that I seek from any service. The traffic distribution is quite reliable even under heavier loads, and SSL offloading has helped reduce the burden on my backend server, especially when I saw three to four times higher traffic than usual during sales. I also appreciate the flexibility in configuring policies, giving good control without being overly complicated. A10 Networks Thunder ADC handles high traffic volumes very efficiently, showing consistent response times even during the spikes I mentioned. SSL offloading is one of the key features that I was seeking, significantly improving my backend performance. Overall, all these features feel optimized for speed and stability because, in the end, I also want my client to have the best experience.

After enabling SSL offloading, the most noticeable change was reduced CPU utilization on my backend servers because that was taking much more load and cost at my backend and my working capital. Reduced CPU utilization on my backend servers was a game-changer, as a good portion of resources was going into handling encryption and decryption before I shifted that load to A10 Networks Thunder ADC. I saw roughly around a fifteen to thirty percent drop in CPU usage during peak hours, translating into better response times and more headroom for handling additional traffic and more clients, becoming very cost-efficient for me as a company.

The CPU usage and response times have definitely impacted my organization positively, with A10 Networks Thunder ADC handling SSL offloading and providing my backend systems with more headroom. From an end-user perspective, the improvements translate into faster and more consistent response times, and that reliability has been a clear positive for me, especially during high traffic times that I mentioned multiple times. I definitely received fewer complaints, and the differences are huge. After implementing SSL offloading on A10 Networks Thunder ADC, performance became more consistent, especially during peak traffic. I saw fewer complaints around slow response times, and overall, the experience felt smoother from the client side.

What needs improvement?

One area where A10 Networks Thunder ADC could improve is the user interface, which is functional but not the most intuitive, especially for new users, making it a bit under-utilized. Some workflows take a bit of time to get used to, and simplifying the UI would make onboarding much easier.

I want to add that around documentation, the core capabilities of A10 Networks Thunder ADC are strong, and having more structured, real-world configuration examples would make a big difference, especially for teams that are new to the platform, helping reduce the initial learning curve for them.

For how long have I used the solution?

I have been using A10 Networks Thunder ADC for the last three years.

What do I think about the stability of the solution?

A10 Networks Thunder ADC is sometimes stable in my experience, but I am not certain about this assessment. It is not really bad and not a major downtime issue. Most of the time, it just runs in the background without issues.

What do I think about the scalability of the solution?

A10 Networks Thunder ADC can handle growth easily, and I have scaled up during higher traffic periods.

Which other solutions did I evaluate?

Before choosing A10 Networks Thunder ADC, I do not know if the organization evaluated other options, but I assume they were discussing Citrix ADC.

What other advice do I have?

I would advise others looking into using A10 Networks Thunder ADC to integrate it nicely, as it is a powerful solution, and you will get the most value when your architecture, traffic flows, and policies are clearly defined upfront. Also, take time to understand its advanced features gradually rather than trying to use everything at once, getting into it slowly. I would rate this product an eight out of ten.

Reliable availability and flexible licensing have supported critical application performance

  • March 13, 2026
  • Review from a verified AWS customer

What is most valuable?

According to my understanding, the licensing model and the application availability time in A10 Networks Thunder ADC provide a good solution for all operation-critical customers, and they might find the high availability feature very useful.

Application load balancing in A10 Networks Thunder ADC plays a crucial role in improving application reliability during peak periods.

I believe that A10 Networks Thunder ADC utilizes technology with one of the protocols in its load balancing solutions, and I think it's a great solution that I found in the market. I conducted research and clearly see their licensing model and the technical methodology to connect and maintain high availability, which I think are the major features highlighted in the solution.

What needs improvement?

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. I think that is the main improvement that should be addressed in the next couple of years.

In the Sri Lankan market, we mainly expect a budget-friendly option for physical appliances from A10 Networks Thunder ADC, particularly in the 3GB to 6GB range, while they are currently releasing a hardware appliance for 10G bandwidth throughput. I think that should be improved much better.

Recently, government taxes have increased A10 Networks Thunder ADC prices according to their taxing policies. For the moment, I think we can go with a competitive price, even though sometimes we face a similar price to our competitive products. If that can be adjusted, that would be better.

In the vThunder series of A10 Networks Thunder ADC, they have a perpetual license model and a subscription model, but in the Thunder series, the physical appliance does not have a perpetual license model, mainly operating on the subscription model. I think adding that feature could expand the market. Specifically, I want to highlight that a low number of throughput can be released to at least the APAC region, which will be very useful. At the perimeter level, we don't have access to implement the virtual appliance model and must use a hardware box. Compared to the current release version, we cannot match their budget with a good price, so that is my primary expectation. If there is any chance to launch a box with 3 to 6 throughput, I think that would be better, as we could easily switch to our BFSI and enterprise customers, who have a big pain point in their firewall load balancing. However, the challenge remains that we cannot deploy a virtual appliance there and must go with a physical appliance, so making that adjustment would create a good opportunity to expand the market.

How are customer service and support?

I can give A10 Networks Thunder ADC a rating of 10 out of 10. Their tech support is very responsible, and their response time is very low, providing superb support.

Which solution did I use previously and why did I switch?

Before A10 Networks Thunder ADC, I handled the WAF solution. I joined as a product manager for the WAF solution, and I previously worked for the SI industry in Sri Lanka, where I highlighted that WAF is the main requirement for the Sri Lankan market infrastructure.

What other advice do I have?

I didn't have a chance to capture those areas regarding A10 Networks Thunder ADC caching and compression features. The previously mentioned areas are covered from my requirement gathering and customer meetups.

As per my experience, the vThunder series of A10 Networks Thunder ADC is very easy to deploy, and the cost is also very reliable and justifiable. On the physical appliance side, they have added WAF and all, resulting in a higher cost while ensuring reliability. They guarantee 10-16 years online for that physical appliance, which is very beneficial for the Telco and BFSI side.

For the moment, I haven't had any kind of scenario with A10 Networks Thunder ADC multi-cloud support.

I didn't have a chance to explore A10 Networks Thunder ADC analytics tools.

I can give A10 Networks Thunder ADC an overall rating of nine out of ten as a product.

In some of our deployments of A10 Networks Thunder ADC, we have employed DDoS and other security features, and for the past few years, we haven't experienced any major incidents, although there were minor incidents related to some airline and other customer DDoS attacks that A10 couldn't mitigate.

How are customer service and support?

There are no complexities with the deployment of A10 Networks Thunder ADC feature-wise; it's entirely acceptable. However, when it comes to customer requirements, sometimes it's difficult to manage some requirements because they expect features that require another product, leading to some challenges. Other than that, the product is fine, so we can easily manage everything.

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.

How would you rate customer service and support?

How was the initial setup?

Normally, deployment of A10 Networks Thunder ADC takes around two to three days based on the customer requirement, and sometimes it is extended for one week.

A10 Networks Thunder ADC was purchased through AWS Marketplace.

What about the implementation team?

I do not directly involve myself in the deployment due to my job role, but I manage and handle the team that is directly involved. When there is an issue, then I am also involved.

Normally, there are two people in each deployment, one being the main engineer who is handling the deployment, so we prioritize having two engineers per deployment as much as possible.

What was our ROI?

We do see a return on investment and cost reductions after the implementation of A10 Networks Thunder ADC, as I mentioned earlier regarding an incident related to one airline company.

What's my experience with pricing, setup cost, and licensing?

I estimate that I can save around 20 to 30 percent of my budget with A10 Networks Thunder ADC, though it's not an exact figure.

Which other solutions did I evaluate?

We are working with some other vendors, not only A10 Networks.

Currently, we are working with tools such as F5 from other vendors.

What other advice do I have?

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.

Which deployment model are you using for this solution?

Public Cloud

Protects connection and servers from direct access with control access feature

  • July 08, 2024
  • Review provided by PeerSpot

What is our primary use case?

We use the solution for ProTechVIP, the software, the client, the servers, and the firewalls. We mix them, protecting the connection and the servers from direct access.

How has it helped my organization?

We can control access based on the specific application. If other devices are attempting to directly access the servers, you can block them. Additionally, you can balance the load among servers to optimize performance. For example, utilizing caching can make the application run faster.

What is most valuable?

It's very simple to use.

What needs improvement?

The product is expensive.

For how long have I used the solution?

I have been using A10 Networks Thunder ADC as a partner for over two years.

What do I think about the stability of the solution?

The solution’s stability is very good.

What do I think about the scalability of the solution?

The solution’s scalability is good. We also sell directly to the government, sometimes more than 20 boxes.

How are customer service and support?

If you need more specific guys, it takes time, or you can get support from them. After sending many emails, Thunder calls directly to talk, and then we can talk.

How was the initial setup?

The initial setup is very simple. The issue is that it achieves high output across all its features, specifically the output ports. This affects the customer's solution because sometimes, the customer is even aware of the user's activity on certain servers. If you have all the necessary information, we can quickly deploy the solution within two to three days.

The size of the Thunder ADC depends on its configuration. For example, the cache converter typically includes more than two rack units, often requiring at least three rack units for adequate space.

I rate it a ten out of ten, where one is difficult, and ten is easy.

What was our ROI?

ROI is very good because it optimizes the process.

What's my experience with pricing, setup cost, and licensing?

I rate the product’s pricing a nine out of ten, where one is cheap and ten is expensive. However, When you use KPS, I rate it five because it's very expensive.

What other advice do I have?

A10 Networks' Thunder ADC is being sold by adding hardware (HxD) and configuring certain aspects like the Exponent. These modified versions are sold directly to customers. They are using HPANETX Thunder models, some of which originate from JTerrin. I believe these models come from Microsoft, which has a significant data analytics contract. Here in Brazil, UsersBox is being utilized, and there is an issue when I try to sell a new box from ATEM. My box is five times more expensive than the other one. I sent the box's serial number to GuidePhone A10 for verification, and it turns out that the box is from Microsoft Japan. Despite the conference being for Microsoft Japan, these boxes somehow ended up here in Brazil.

The solution requires less maintenance.

The A10 Networks Thunder ADC can be more expensive than alternatives offering similar performance. Another issue is its architecture: when using our software architecture, there are limitations when creating new instances, such as a new VS. Typically, with solutions like F5, you need to define and allocate resources upfront when creating a new instance. If you need more resources allocated to a Virtual Service, you must often delete and recreate it. In contrast, A10 Networks allows for more flexible resource allocation adjustments without needing to recreate the instance.

Overall, I rate the solution a nine out of ten.
