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.

Identifying compromised traffic and securing data has been a significant advantage

One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) ( /products/f5-big-ip-local-traffic-manager-ltm-reviews ) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.

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."

"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."

"It's a very friendly solution, easy to configure and it's very flexible."

"The solution is flexible."

"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."

"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."

"We have two appliances and I'm able to move my application from one appliance to another. I don't have to move my whole A10 to be active on the other side or to be passive on the other side. If an application is having a problem, I can just move it using a command."

"It is very useful to have a simple dashboard where you can login and look into what your traffic patterns are, then look and see what times of day you're experiencing the heaviest traffic. You can quickly identify if you are possibly having a security issue or security breach. It makes it very easy to use the box."

More A10 Networks Thunder ADC pros

"It makes the publishing of applications to the Internet safer."

"You can create multiple virtual servers on F5 BIG-IP technology, and within multiple virtual servers you can have multiple nodes, where a node equals two application servers."

"Users can see a remarkable performance difference from a qualitative sense."

"The most helpful thing is that it's open-source. It's very easy to program and customize."

"F5 BIG-IP Local Traffic Manager is a stable and reliable solution."

"There is a lot of documentation available."

"There were a lot of good features. The most beneficial for maintaining server health included the algorithms for the virtual IP, which segment traffic between servers, authentication profiles, and many other things."

"NetFlow balancing and traffic balancing are good features."

More F5 BIG-IP Local Traffic Manager (LTM) pros

"Stability is number one."

"The support for all major Linux distros makes running and testing a breeze."

"We use the solution for load balancing."

"The features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests."

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

"It is a crucial tool in ensuring smooth service provision without any interruptions."

"We don't have a problem with the user interface. it's good."

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

More HAProxy pros

Cons

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

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

"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."

"Traffic flow issues are very difficult, as there's no means for us to analyze the traffic coming in or out of the appliance without technical support."

"The solution does logging, but the logging capacity is really small. Because we have a bunch of traffic here, we usually get a logging-side warning that "This many logs were lost because of the heavy traffic." If the logging was better, that would be very good."

"The product is expensive."

"There are competitors that have more features."

"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."

More A10 Networks Thunder ADC cons

"Right now, there are a lot of products within F5's portfolio. They acquired a couple of companies like NGINX and Volterra. Some features and technologies overlapped when this acquisition occurred. They need to refine it and come up with a single, proper solution. F5 should focus more on zero trust network access (ZTNA).They should be more focused on that framework because the industry is moving towards that. Everyone is talking about SASE and zero trust."

"It would be good to have better traffic and better data. It would be nice to have more granularity to see packets in terms of the header details, the analytics, etc. It would be nice if that was also part of it and to have analytics added to the traffic."

"I wouldn't recommend the tool to small companies, considering its high price and the infrastructure needs of small businesses."

"The auto logout feature after three minutes is terrible. I wish they would make that longer, since it is not a feature that we can change."

"The web interface could be better."

"In terms of what could be improved, I would expect more integration with different platforms and more integration with the backend systems. Additionally, in the next release, I would like a more secure version."

"This is a very expensive solution."

"The UI could be improved."

More F5 BIG-IP Local Traffic Manager (LTM) cons

"The web stats UI, which provides the status of the health and numbers, could greatly benefit from having a RESTful interface to control the load-balanced nodes. Although there is a hack around the UI (by issuing a POST request to HAProxy with parameters), a RESTful interface would greatly improve the automation process (through Chef and Ansible)."

"The product does not have any new technologies."

"Documentation could be improved."

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

"It needs proper HTTP/2 support."

"If nbproc = 2, you will have two processes of HAProxy running. However, the stats of HAProxy will not be aggregated, meaning you don't really know the collective status in a single point of view."

"Pricing, monitoring, and reports can be improved."

"The basic clustering is not usable in our very specific setup. The clustering is mainly a configuration replication and is great in a case of active-passive usage. In the case of an active-active (or with more than two nodes) where the configuration is not fully identical, it cannot be used as-is."

More HAProxy cons

Pricing and Cost Advice

"The pricing is fine, considering the features they are providing. If you are an individual user, they'll price the product differently compared to how they price the product that is sold to an organization."

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

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

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

"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 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."

"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."

More A10 Networks Thunder ADC pricing and cost advice

"F5 isn’t cheap but is worth the price."

"The pricing is inclusive of many features."

"The price should be reduced because it is expensive when compared to the competition."

"Unless the price difference is large, this is not the primary concern for the product. The performance and product-related issues (secure for VPN, multi-function for network device, etc.) are the keys."

"It is a little pricey. I wish the pricing was cheaper, but I wish the pricing was cheaper for everything."

"The price of F5 BIG-IP LTM could improve."

"The price is high."

"Compared to using open-source products, the prices are not cheap."

More F5 BIG-IP Local Traffic Manager (LTM) pricing and cost advice

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

"We are using HAProxy as an open-source."

"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible."

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."

"HAProxy is an open-source solution."

"Very good value for the money. One of the simplest licensing schemes in this category of products."

"The licensing fee for the solution is $690 per unit annually."

"HAProxy is free software. There are optional paid products (support/appliances)."

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.
