Stable, performs well, and the iRules functionality is very good
Pros and Cons
- "I've worked a little bit with iRules and it is amazing."
- "Technical support is somewhat slow and could be improved."
What is our primary use case?
What is most valuable?
Our deployment is not very complicated, from my point of view. The HTTP and HTTPS load balancing mechanisms are the core functionality for me. I have done things like created new virtual servers, changed the load balancing, and looked at statistics, but I have not looked into the security features, API gateways, and other features because that is the responsibility of other departments. As a pure network engineer, I think the box is performing very well.
I've worked a little bit with iRules and it is amazing. As long as you know what you're doing, it does everything you want it to do.
What needs improvement?
Technical support is somewhat slow and could be improved.
For how long have I used the solution?
I have been working with F5 BIG-IP for the past two years.

881,821 professionals have used our research since 2012.
How are customer service and support?
My experience with technical support has come from two or three tickets that I have raised over the past two years. I would rate them a six or seven out of ten. I'm not sure if my colleagues have faced the same issues, but I have experienced delays in response, especially when I opened a case for iRules. It took them about a month and a half to get me to the point.
One of the reasons it took as long was because they considered this to be a problem for professional services, and not technical support. As such, it was not marked as urgent.
Which solution did I use previously and why did I switch?
F5 was the first load balancer that I worked on.
How was the initial setup?
The provisioning of the box from A to Z is of medium difficulty. It is not very complicated, nor very easy. I would rate it a seven out of ten in terms of provisioning it for the first time.
What's my experience with pricing, setup cost, and licensing?
Compared to using open-source products, the prices are not cheap.
Which other solutions did I evaluate?
Although we are happy with F5, we are currently evaluating NGINX and Kemp LoadMaster because our F5 boxes are approaching end-of-life. We are running them as demos, conducting a PoC for each to test and see how they run in our environment. There are several things that I have yet to test with these other products.
My understanding is that the support packages and the boxes themselves are not very cheap.
If ultimately we find that the other solutions do not meet our requirements then we will be renewing our service with F5.
What other advice do I have?
To this point, whatever we have needed has been available out-of-the-box. In our environment, we have not experienced limitations.
In summary, we are happy with the product and for me, it's ideal for HTTP and HTTPS.
Performance-wise, stability-wise, and feature-wise, I would rate this solution an eight out of ten.

Capable of handling huge workloads, good stability, and good scalability
Pros and Cons
- "One of the greatest things about F5 Load Balancer is that it provides additional capability for handling huge workloads and routing them to an SAP or non-SAP application. It is capable of supporting a large amount of user workload and application connectivity workload. This was the main reason why we chose F5."
- "It is a hardware load balancer, and its installation procedure is more complex than a software load balancer. There are pros and cons of using hardware load balancing. You have to have specific hardware deployed in your data center to activate this load balancer. They never came up with any software-based load balancing solution. It is all hardware-based."
What is our primary use case?
We use it for load balancing any kind of HTTP and HTTPS traffic coming from users or other systems.
What is most valuable?

I have been using this solution for a couple of years.
What do I think about the stability of the solution?
Its stability is good.
What do I think about the scalability of the solution?
It is scalable. We have around 2,000 plus users.
How are customer service and technical support?
Their technical support is fine.
How was the initial setup?
It is a hardware load balancer, so its installation procedure is more complex than a software load balancer. You need specific hardware to install this load balancer.
Which other solutions did I evaluate?
We had evaluated a few SAP solutions, but we found F5 to be more suitable at that time.
What other advice do I have?
I would recommend this solution. We have been using it for such a long time, and we are quite happy with it as an organization. It is awesome, and we plan to keep using it till we are on-prem. It has been good for our on-prem setup.
I would rate this solution an eight out of ten. I am quite satisfied with this solution.
Which deployment model are you using for this solution?
On-premises

Design and Conception Engineer at a comms service provider with 5,001-10,000 employees
Inadequate virtual machine support, but stable and secure
Pros and Cons
- "In my team, we work in a very agile environment and the solutions from BIG-IP, including BIG-IP WAF, suit us well when developing and serving our applications."
- "There are some aspects of F5 BIG-IP that could be improved, the main one being virtual machine support. We have seen that even with the virtual editions, there are some things that we would like to do that are currently not possible with virtual machines."
What is our primary use case?
Our engineers use various products from the F5 BIG-IP range when creating application solutions. Primarily, we make use of F5 BIG-IP's ASM (Application Security Manager) and WAF (Web Application Firewall). For most of our applications, we require that our servers, and server-related software, are hosted in virtual machine environments.
How has it helped my organization?
In my team, we work in a very agile environment and the solutions from BIG-IP, including BIG-IP WAF, suit us well when developing and serving our applications.
What is most valuable?
I am happy with most of the features made available to us through BIG-IP's software and I enjoy using the interfaces (dashboards, etc.).
What needs improvement?
There are some aspects of F5 BIG-IP that could be improved, the main one being virtual machine support. We have seen that even with the virtual editions, there are some things that we would like to do that are currently not possible with virtual machines.
We have seen some problems mainly with F5 BIG-IP ASM, and so I think the virtual editions of the ASM could be improved.
Another negative aspect is the cost, as it can be expensive.
For how long have I used the solution?
I have been using F5 BIG-IP for five years now.
What do I think about the stability of the solution?
As far as I can tell, it's a stable and secure solution.
What do I think about the scalability of the solution?
Although BIG-IP's solutions are scalable for most purposes, it's not always scalable for certain scenarios, in my opinion. From an API perspective, though, it is quite scalable.
How are customer service and technical support?
We have used F5 BIG-IP's technical support and it is very good.
How was the initial setup?
The initial setup is very easy. Very, very easy. Especially for the web guys.
What's my experience with pricing, setup cost, and licensing?
F5 BIG-IP can be expensive, although there are trial versions available which are helpful to find out if the solution is right for your company.
Which other solutions did I evaluate?
We have been considering using Nginx as an alternative or complementary solution to our application delivery and security needs, but we have not pursued this option further at this point.
For the most part, we are looking for a solution that has better support for virtual machines, and Nginx is one alternative we have looked at because of its good virtual machine support.
What other advice do I have?
I would rate F5 BIG-IP a five out of ten.
Which deployment model are you using for this solution?

Flexible with good technical support and horizontal scalability
Pros and Cons
- "The product is quite flexible."
- "The cost of the solution is pretty high. It would be ideal if it was more reasonable."
What is our primary use case?
The F5 is something we purchased for another project that has not been turned on just yet.
What is most valuable?
The solution is very powerful.
The product is quite flexible.
The horizontal scalability that is on offer is very good as well.
What needs improvement?
I would like to see some better documentation focused on our website and better search criteria. That's probably the best way to say that there needs to help with research.
The cost of the solution is pretty high. It would be ideal if it was more reasonable.
For how long have I used the solution?
We were originally supposed to launch this project for a client, however, that hasn't materialized yet.
What do I think about the scalability of the solution?
While we never really got around to scaling the solution just yet, there is horizontal scalability that is on offer that seems very good.
This is being deployed in a service provider environment. Therefore, it'll be impactful to all of our customers. However, I would say as far as internal support users, we have a team of probably ten that'll be supporting this product once it's launched in production.
How are customer service and technical support?
In terms of technical support, so far it has been pretty good. That said, it's more to set up the solution versus actual production support. They're not helping us deal with bugs or glitches, they've just been helping us with a rather complex implementation. We've been satisfied with their assistance in that sense. They seem knowledgeable and responsive.
How was the initial setup?
The initial setup is largely complex. However, we had a lot of help from their internal sales team or support team has been important in terms of working around the difficulties.
We have a staff of ten that are handling deployment and maintenance. They're not dedicated just to this product, however. They support our overall service provider architecture.
What's my experience with pricing, setup cost, and licensing?
The cost is quite high. The long-term support in particular is quite high.
Customers need to be aware that each feature is licensable, which allows costs to accrue.
What other advice do I have?
We're just a customer. We don't have a business relationship with F5.
The F5 is something we purchased for another project that has not yet been turned up. That said, the experience I've had with F5 has been very positive, specifically working directly with their corporate sales engineering team.
Overall, I'd rate the solution eight out of ten. If it wasn't for the high cost of the product, I might rate it a bit higher.
I would advise those considering the solution to explore all options. Specifically, the total cost of ownership. It can be lower with some other vendors. A10 is oftentimes a lower cost of ownership. One challenge with F5 is everything is a licensable feature. Whereas something like an A10 is not. You see the same challenges with a Cisco type of device as well, however, it's in a different arena, with different products.

Feature rich, reliable, with good load balancing capabilities and good technical support
Pros and Cons
- "F5 has many capabilities for load balancing and web application firewall features."
- "The logging features are too limited and do not give us a solid understanding of what's happening."
What is our primary use case?
We are using this solution for the web application firewall and load balancing.
What is most valuable?
F5 has many capabilities for load balancing and web application firewall features.
What needs improvement?
There should be more logging improvements on F5. The logging features are too limited and do not give us a solid understanding of what's happening. For example, the web application firewall logs don't say complete, or why this is blocked, which signature or which root cause is blocking the log.
Also, it can provide more understandable windows or dashboards regarding the latency of the application.
Citrix has cheap tools that show what is happening and describe why did they happen.
I would like to see improvements to the dashboard, latency reporting, and monitoring. Improvements in these areas would be very valuable.
For how long have I used the solution?
I have been using F5 for approximately four years.
What do I think about the stability of the solution?
F5 is very stable. We have gone 300 days with no failures.
What do I think about the scalability of the solution?
In regards to scalability, I have never experienced any bottlenecks of the hardware or the features of F5. F5 doesn't have any latencies.
With Citrix, at times we experience some latencies when the web application requires more complex directions, inspections, and more complex load balancing features.
The number of users is variant. Currently, we have more than 10,000 users.
How are customer service and technical support?
I have not experienced any issues with technical support.
Which solution did I use previously and why did I switch?
Citrix doesn't have as many options.
If you were to compare Citrix with F5, the pros of F5 is the idle features. It's very powerful and you can do tons of work with a few lines.
With Citrix, you have to learn and understand the regular expressions, but the regular expressions consume a lot of the hardware. Also, it is much more complicated.
What's my experience with pricing, setup cost, and licensing?
F5 pricing is too high, compared to Citrix.
If a big sector or a company needs more security and more control over applications and the ADC, F5 is the best choice. But if a company needs only an ADC, without the web application firewall features, Citrix is fine.
What other advice do I have?
For those who are interested in this solution and you want more control over the applications then F5 is fine.
In the future, F5 will be our first choice, but everything can change.
What happens with the next features, we don't know. Maybe Citrix will overcome the problems and will become a more powerful tool than F5.
Without consideration of the price, I would rate this solution a ten out of ten.
Which deployment model are you using for this solution?

It's like a Swiss Army knife, and you can scale it horizontally or vertically as much as you want
Pros and Cons
- "BIG-IP can do anything. It's like a Swiss Army knife."
- "BIG-IP LTM is taking a long time to mature in cloud environments. They plan to improve cloud integration in the next version, but it isn't out yet. It's essential because more companies are moving to the cloud these days and using things like Kubernetes or microservices. F5 needs to improve in that direction, and they are."
What is our primary use case?
BIG-IP has multiple uses, including VPN, application firewall, and load balancing.
What is most valuable?
BIG-IP can do anything. It's like a Swiss Army knife.
What needs improvement?
BIG-IP LTM is taking a long time to mature in cloud environments. They plan to improve cloud integration in the next version, but it isn't out yet. It's essential because more companies are moving to the cloud these days and using things like Kubernetes or microservices. F5 needs to improve in that direction, and they are.
For how long have I used the solution?
I have used BIG-IP for about 15 years
What do I think about the stability of the solution?
BIG-IP LTM's hardware is stable, and the operating system is great.
What do I think about the scalability of the solution?
BIG-IP can scale horizontally or vertically because it's a blade system. If you need more hardware on the same appliance, you can put blades on it. They are a bit expensive but work fine. You can create a cluster if you want to scale horizontally and put any hardware you need on it. You can scale as much as you want.
How are customer service and support?
I rate F5 support seven out of 10. The response time is okay, but sometimes you have to explain your issue to multiple support engineers before it gets resolved. It's a common issue with most tech support.
How would you rate customer service and support?
Neutral
How was the initial setup?
Setting up BIG-IP LTM was complicated in the beginning, but it has gotten easier over time. The deployment time varies depending on your environment. You have to connect and activate the license, but the operating system and modules are pre-installed. The basic setup takes only an hour, but you might need to do some additional configuration.
What's my experience with pricing, setup cost, and licensing?
BIG-IP LTM is somewhat pricey for a small company with a limited budget.
Which deployment model are you using for this solution?
On-premises
