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

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.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 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.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 ease of use is very good. It's very robust. It just sits and works.A10 explained why the latency dropped significantly on a site that we have.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.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.

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.There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff.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.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 user interface is what people complain about most of the time, particularly if they don't use it very often. Then they complain that it's a bit clunky.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.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.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 security is okay, but the monitoring and reporting need improvement.ADC from Citrix has added functionalities from other products and the usability is very difficult for someone who is used to a simpler user interface, it's a little bit of a mess to use.Too many bugs in the software and it's always difficult when you need to update.The WAF component needs to be simplified so that it is easier to use.I will try to migrate all the tools to the cloud because there is more lab and more VPN scalability available in the cloud. It is not available on-premises.Some of our customers have questioned the security of this solution lately, wondering whether it is safe or not, so enhancements in this respect would be good.I think the documentation should be improved.We have issues with the certificates. All authorization processes need certificates, however, every three months we needed to change certificates. This process iss complicated for us because Citrix does not have a not user-friendly interface and does not off user-friendly services. This needs a lot of improvement.

Pricing and Cost Advice
You get a lot more for your dollar with A10.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.We just pay for support in addition to our licensing.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.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.It is $7000 per unit for the support annually.We previously had F5 and switched because of costs.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.

When compared to other solutions, the cost is high.Our licensing fees including technical support are approximately $3,500 USD.The licensing costs for this solution vary depending on which model is being used.Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for.We have a yearly licencing fee, and there are no additional costs.Ninety day free trial makes it easy to try out this solution.Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much.NetScaler does the same thing as an F5 and it's cheaper.
