Executive SummaryUpdated on Dec 17, 2024

A10 Networks Thunder ADC and HAProxy compete in the load balancing and traffic management category. A10 Networks holds the upper hand due to its robust security features and integrated licensing compared to HAProxy's open-source and customizable approach lacking inbuilt security.

Features: A10 Networks Thunder ADC offers an all-inclusive licensing model, advanced traffic management, and optional security features through third-party firewalls. It provides DDoS protection and IPv6 support. HAProxy provides efficient load balancing, protocol-level traffic handling, and advanced LB algorithms, focusing on customization through scripting.

Room for Improvement: A10 Networks faces challenges with limited third-party integrations and potential support delays due to overseas centers. HAProxy needs improved logging, user-friendly documentation, and robust security features, with a more modular design and native cluster support.

Ease of Deployment and Customer Service: A10 Networks boasts strong support, although some users note response delays. On-premises deployment is common and support services receive positive ratings. HAProxy enables flexible deployment across environments but relies heavily on community support, with paid support available for critical needs.

Pricing and ROI: A10 Networks is cost-effective compared to F5, offering an ROI through simplified configuration and reduced operational costs. HAProxy's open-source nature results in affordability, with expenses focused on optional paid support or advanced features, providing a cost-effective solution for performant load balancing.

Protects connection and servers from direct access with control access feature

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.

Useful for for small and quick load-balancing tasks

What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.

Quotes from Members

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

Pros

"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 has positively impacted my organization by providing better visibility of the content served to customers and allowing us to see what's going on, including possible attack vectors and exposed information."

"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."

"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."

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

"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."

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

"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."

More A10 Networks Thunder ADC pros

"We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host."

"It has allowed us to evenly distribute the load across a number of servers, and check their health and automatically react to errors."

"Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind."

"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."

"It is scalable."

"It reduced the load on our main load balancers."

"What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks."

"We use it as a load balancer for our application servers."

More HAProxy pros

Cons

"The documentation should be better, as it is missing user scenarios; some features are not documented very well, leading to difficulties understanding some straightforward features."

"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."

"I would like them to provide learning tips and a community forum where users can share ideas. They need more detailed support articles on the A10 website."

"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."

"The product is expensive."

"Currently, the solution's WAF features are fewer. They should consider increasing their WAF features."

"The user interface is not as pretty as it could be."

More A10 Networks Thunder ADC cons

"There is no standardized document available. So, any individual has to work from scratch to work it out. If some standard deployment details are available, it would be helpful for people while deploying it. There should be more documentation on the standard deployment."

"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."

"The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs."

"Dynamic update API. More things should be possible to be configured during runtime."

"The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration. A GUI/web interface could be helpful for users who are not as experienced in the Linux shell. However, HAProxy does have another product that we evaluated called ALOHA, which has a web front-end, but we found it did not meet our needs."

"We've changed solutions as it doesn't fit with our current needs."

"Maybe HAProxy could be more modular."

"The solution's dashboards and reports could be improved."

More HAProxy cons

Pricing and Cost Advice

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

"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."

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

"The solution costs less than its competitors."

"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."

"The price is good they are very comparative."

"As for the initial investment in the hardware, F5 and A10 are quite similar now. For the current A10 solution, the initial cost was about $36,000. As for annual support, the F5 solution would be between $10,000 and $12,000, while the A10 is $2,200 a year for support."

More A10 Networks Thunder ADC pricing and cost advice

"The product is open source."

"I use the open-source version of the product. I don't have experience with the licensed version of the solution."

"HAProxy is free in the initial offer. However, pricing can be improved."

"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."

"The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy."

"It is free of cost."

"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."

"HAProxy is an open-source solution."

Reviews from Real Users

“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
