Improves the resilience and quality of the application but needs more data granularity
Pros and Cons
- "F5 BIG-IP Local Traffic Manager (LTM) improves the resilience and quality of the application itself, the speed and the user experience for the application. The data that the users need from the application is actually acquired faster. So, it provides faster data acquisition."
- "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."
What is our primary use case?
We use it for server management and application traffic, that is, to load balance between traffic for applications coming from their service. Users coming in are then able to have their traffic go to the service that has the suitable resources or adequate resources.
What is most valuable?

It also provides lower latency.
What needs improvement?
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.
For how long have I used the solution?
I've been using it for two years.
What do I think about the stability of the solution?
F5 BIG-IP Local Traffic Manager (LTM) is pretty stable. It's one of the most stable products that I know, when it comes to load balancing and traffic.
What do I think about the scalability of the solution?
It is very scalable. We have thousands of users.
How are customer service and support?
The technical support is top notch.
How was the initial setup?
It is pretty easy to set up.
Because there were other parties involved, the deployment took us about a week. Normally, it takes a couple of hours.
What about the implementation team?
We did it in-house.
What other advice do I have?
I would advise you to go for it because it's one of the top three solutions in my opinion. I would rate it at seven on a scale from one to ten.

Highly scalable, exceedingly stable, and responsive technical support
Pros and Cons
- "F5 BIG-IP Local Traffic Manager (LTM) is very easy to use, from SSL Management to enabling, disabling loads, applications, systems, and monitoring. Overall the solution keeps our application functional from a client's perspective 24 hours a day, seven days a week."
- "The solution could improve the documentation."
What is our primary use case?
We use F5 BIG-IP Local Traffic Manager (LTM) as a load balancing solution. We use many of the features associated with the solution, such as the Local Traffic Manager and Access Analytics that are associated with the SSL.
What is most valuable?
F5 BIG-IP Local Traffic Manager (LTM) is very easy to use, from SSL Management to enabling, disabling loads, applications, systems, and monitoring. Overall the solution keeps our application functional from a client's perspective 24 hours a day, seven days a week. We have rules that are set up to detect if any part of the application in one of the nodes is not functioning correctly, having a problem, or is experiencing any sort of error, it will automatically pull it out of the load balance bundle and alerts somebody to go take action and at the address. This means our clients are happy because they are not receiving strange errors because somebody's typed something somewhere incorrectly and we are happy because our uptime is reliable.
What needs improvement?
The solution could improve the documentation.
For how long have I used the solution?
I have been using F5 BIG-IP Local Traffic Manager (LTM) for approximately
What do I think about the stability of the solution?
The stability is very good. We have to power off a system to reboot it after firmware or other updates, but I have not had a problem with the stability of the units at all. We had a system cluster go down but that was a physical issue with the hard drive. They shipped us out a new one, plugged it back in, and it almost self-configures. We had to put some details in the hard drive, but it takes the configuration from the other units and runs well. We have had zero downtime over the last five years.
What do I think about the scalability of the solution?
F5 BIG-IP Local Traffic Manager (LTM) is very scalable. We have recently expanded the cluster to five nodes and I am running in an active scenario. I did the upgrade live and it did not require any downtime.
How are customer service and support?
The technical support is good. I have not had any problem asking questions that a support person can not answer. Technical support is not engineering and that was something that I had to learn. If you have something that is already functional and you need to figure out why it stopped working, why it is now broken, or you did an upgrade and something is wrong, the technical support can help with that. I have called them a dozen times over the five years and they have had my issue resolved within approximately one hour.
How was the initial setup?
Setting up the solution on the systems is not difficult but enabling applications and configuration can be complex. The difficulty level can also depend on the environment, we have a more complex environment. You have to have some base knowledge of the solution for what you are doing before you can go do it. Configuring the solution is not something that a layperson is going to be able to do. You have to know what you are looking for before you will be able to find it.
What other advice do I have?
My advice to those wanting to implement this solution is they need to do their research ahead of time and know what problems you are trying to solve. In our case, our solutions engineer from F5 directly has been amazing. If you receive a good team in account management, they can point you in the right direction, and in a lot of cases, they can get you moving along. The support from him has been tremendous, it has been extremely valuable.
Our configuration is not simple. There is some custom code that is written in our system, but everything works as they say it should, it is a great solution.
I rate F5 BIG-IP Local Traffic Manager (LTM) an eight out of ten.

Stable with good security and reliability
Pros and Cons
- "The stability is excellent."
- "The pricing of the product is a bit too high."
What is our primary use case?
We primarily use the solution for security purposes.
What is most valuable?
The security on offer from the solution is very good.
The stability is excellent.
What needs improvement?
The pricing of the product is a bit too high. They should work to make it more affordable. It needs to be more cost-efficient.
What do I think about the stability of the solution?
The solution is very stable. There are no bugs or glitches. It doesn't crash or freeze. It's reliable and the performance has been good.
How are customer service and technical support?
I've never used technical support. I can't speak to how helpful or responsive they are when it comes to servicing their customers, having never used them personally.
Which solution did I use previously and why did I switch?
I also have experience with Check Point.
How was the initial setup?
We did not install the solution ourselves. We used an integrator that handled the process and helped us set everything up.
What about the implementation team?
We used an integrator to assist with the installation. We were pleased with the results. There was nothing to complain about the results.
What's my experience with pricing, setup cost, and licensing?
The pricing is pretty high. It's not the least expensive option.
That said, we're willing to pay for the premium security on offer.
What other advice do I have?
I'm a customer and an end-user.
We are using the 12th version of the solution.
I'd rate the solution at a nine out of ten. We've been quite satisfied with the capabilities of the product.

Good customization with knowledgeable and responsive support
Pros and Cons
- "The most valuable feature is customization."
- "I would like to see better integration."
What is our primary use case?
We are using this solution as a load balancer and reverse proxy.
What is most valuable?
The most valuable feature is customization.
What needs improvement?
We are currently using BIG-IP and NetScaler and we wanted to have just one technology. We will be replacing F5 in March.
NetScaler is primarily used for Citrix purposes and BIG-IP is being used as a reverse proxy for our other applications. We would like to manage it easily with one technology.
I would like to see better integration. I can remember when we were implementing ADFS, we had some challenges.
There is not a lot of documentation available where you can refer to and configure any new technologies.
For how long have I used the solution?
I have been working with F5 BIG-IP for approximately seven years but our organization has been using this solution for 13 years.
What do I think about the stability of the solution?
This solution is stable. We have not experienced any issues.
What do I think about the scalability of the solution?
It's a scalable solution and we have not had any limitations. We have approximately 3,000 users.
How are customer service and technical support?
Technical support is very good in terms of their technical knowledge and assistance.
We have had contact with both F5 and Citrix.
F5 has a good technical team who can assist and understand the problem and respond quickly. However, Citrix has been a challenge for us.
How was the initial setup?
When we were setting up for Azure we had some challenges.
We have an internal team of two for maintenance and reporting.
What other advice do I have?
I would definitely recommend this solution to others who are interested in using it.
I need to have a deeper understanding of F5 technology.
I would rate this solution an eight out of ten.
Which deployment model are you using for this solution?
On-premises

Network Security Consultant at Westcon-Comstor
Good load balancing capability and the proxy features give you full control over your traffic
Pros and Cons
- "The most valuable feature is the proxy."
- "If they made it easier for engineers to get F5 training then it would be better."
What is our primary use case?
We are a solution provider and this is one of the products that we implement for our clients.
Some of our clients use it as a load balancer. It can also be used as a web application firewall to protect your web-based applications from attacks.
What is most valuable?
The most valuable feature is the proxy. It is set up as a reverse proxy in front of the server. This feature allows me to do anything with the traffic, such as inspecting it. Most other solutions don't provide you with this capability.
This solution allows you to write scripts that can run on F5 devices. These scripts can be used to monitor traffic and look for keywords, and then perform a corresponding action such as blocking or allowing the request, or giving the user an error.
Big IP supports load balancing from network layer four up to layer seven.
What needs improvement?
More training should be available to customers. There is a guide that is available on the internet, but the training is not as good as others, such as Cisco. While F5 does have a big market share, it is not easy to find a well-training F5 engineer. If they made it easier for engineers to get F5 training then it would be better.
For how long have I used the solution?
I have been working with F5 BIG-IP for five years.
What do I think about the stability of the solution?
This product is very stable. I have seen some instability with newly released versions, so I normally wait for a stable release before I upgrade an older one.
How are customer service and technical support?
I have often been in touch with technical support and most of the time they are good. The response time is usually about one hour, although if it is a priority one issue then they will respond within 40 minutes at the maximum.
How was the initial setup?
The initial setup is straightforward. If the analysis is already complete then it should only take five or ten minutes to deploy.
What's my experience with pricing, setup cost, and licensing?
When you purchase the virtual edition or the hardware, it comes with the base license. There are additional costs depending on what modules or what functionality is required.
What other advice do I have?
I consider F5 to be my network within my network because the traffic has to go through it. This includes things like the load balancer.
My advice for anybody who is implementing this solution is to learn and understand the architecture of the device. It will do very well for you if you understand it.
I would rate this solution a nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

It's stable. They could make the licensing more aligned with the business model.
What needs improvement?
I think the product is a good product. I think where they can improve is in the licensing. It's quite expensive. They could make it more aligned with the business model than with the hardware.
For how long have I used the solution?
I have been using F5 for about two years.
What do I think about the stability of the solution?
It is a stable product but sometimes we have some issues. I have other products that are competitors of F5, and they are also good. The performance of F5 so far is good.
Usually, because we are responsible for providing high availability, we run our architecture with redundancy. Usually, for example, when I have F5, I have a couple of F5s, the active one and the standby one. Today, I had problems. I don't know what happened; it couldn't reload automatically. The other one assumed that I have problems with my infrastructure. That's unfortunately the life of an operations guy.
What do I think about the scalability of the solution?
It is scalable and should meet our future requirements.
How is customer service and technical support?
Technical support is OK. Usually, you don't have direct support from the vendor. You have intermediating in the middle.
How was the initial setup?
The setup is not straightforward. To set up this product, you must know how to do it. Otherwise, you can't do it. It's not plug and play.
What other advice do I have?
They could buy it but there are other choices such as Cisco ACE products, as well. We have it. They are also good. F5 are good. Usually, I'm not locked into one vendor.
The reality is our bookkeeping department unfortunately has a problem with them. Because of that, I have had some issues concerning getting services from the vendor.

Hello there
I have a couple of comments on some points:
Stability Issues:
==> We have deployed F5 LTM, ASM, CGNAT, DNS FW in large and heavy use environments (Telcos, ISPs, Data Centers...) and there was never any stability performance issues in either a single appliance performance, or Failover mechanism
Are you sure there is not routing/Connectivity issues between the two Boxes?
Was the HA tested well upon deployment? maybe there is some mis-configuration that led to this failure in
Initial Setup:
The setup is not straightforward. To set up this product, you must know how to do it. Otherwise, you can't do it. It's not plug and play.
--> Am not sure if you have worked on other reverse proxy solutions or not, but it can never get easier or simpler (or less Steps) from what F5 is providing, on the contrary, configure a new Setup on F5 BIG-IP is considered a straight-forward and fast configuration feature.
I hope you take my comments positively, it's just that i was surprised reading about your bad experience with it, as we've been working with F5 products for more then 5-6 years, and we have a very successful and positive experience, specially in the points you have focused on.
