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.
Bonieber  Orofeo - PeerSpot reviewer
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

"The Global Server Load Balancing (GSLB) is simple to use."
"The solution is stable."
"It's a very friendly solution, easy to configure and it's very flexible."
"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."
"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"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."
"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."
"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."
"The detail that you have available when setting up iRules."
"Valuable features include Link Controller and Server Load Balancer."
"The support from F5 BIG-IP LTM is good."
"We are fond of the load balancing feature for DNS and servers."
"I like that F5 BIG-IP Local Traffic Manager (LTM) is a product that comes with valuable features, but what stands out from all features is load balancing."
"I think F5's tech support may be better than Citrix's because they mainly focus on the ADC product, but Citrix support covers Hypervisor, XenMobile, FAS, and ADC. And from my experience, sometimes, we face some issues that Citrix cannot handle."
"This is a solution that does what it's supposed to do at the price point."
"It provides first-tier firewalling, for you application. And it provides server load-balancing, it provides optimization, and it provides a proxy feature, where your users cannot directly access your server. It acts as a fully proxy architecture. It has client-side and server-side connections, both, and they're separate."
 

Cons

"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."
"They need to make the user interface (GUI) a bit more usable and intuitive. Some features can be a little difficult to find at times. Sometimes, the workflow in the GUI doesn't match the workflow of an actual workflow. E.g., if I want to create a load balancer application, sometimes you've got to do things a bit out of order in the GUI in order to make it work right."
"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."
"A10 Networks Thunder ADC could improve on the Application Delivery Controller. it's not a fully-fledged web application firewall solution. For example, application data and support need to improve."
"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 should add automation features in the next release."
"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."
"The interface and integrated custom applications can be a bit difficult."
"The synchronization does works fairly well. However, if I were to make changes, I would make it easier to start the sync process."
"BIG-IP LTM's sandboxing integration could be improved."
"It requires a particular skill or training before being able to manage it."
"I used GitHub for autoscaling CloudFormation, and I found two bugs and I submitted them. Their implementation in GitHub could be cleaner and allow for a bit more customization."
"It would possibly help to get more training, even better in local languages."
"Improvements should enable customers to build a tailor-made solution in the future through a service portal."
"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."
"F5 BIG-IP Local Traffic Manager could improve by having an FNI feature for a single source to multi-domain load balancing."
 

Pricing and Cost Advice

"The price of the maintenance support is too expensive."
"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."
"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."
"We previously had F5 and switched because of costs."
"Pricing is one of the features of the product that influence customers to use the product."
"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."
"The pricing is a third of the price of the F5 competition."
"You get a lot more for your dollar with A10."
"The price of the solution is sometimes expensive."
"The price is little bit on higher side compared to the cost of NGINX."
"The licensing strategy for F5 is good."
"I am not aware of the exact cost of the product. However, it is expensive."
"F5 is more expensive than other solutions, so you have to be sure F5 is the best solution to fit the requirements."
"The price of F5 BIG-IP LTM could improve."
"Purchasing through the AWS Marketplace was very simple. The main reason that we went this way was the simplicity of buying it there. It is maintained and upgraded for us, and this makes it easy to stay current."
"Try to negotiate all the software features that you require upfront."
