The TMOS of F5 BIG-IP LTM has a mid-layer that is an open source software and the user's management layer which can cause some issues for potential security risks. Other solutions have operating systems that are more secure, such as Cisco, Juniper, and Huawei.

People tend not to use F5 BIG-IP LTM because of this issue. They prefer to use more proprietary solutions, such as Apple solutions which typically can be more secure.

Overall the solution is stable as long as you have the updates and proper configurations.

It is a stable solution. I would rate it an eight out of ten. Rather than having separate appliances for each virtual machine, the F5 BIG-IP Local Traffic Manager (LTM) allows multiple virtual machines to run on one appliance. However, if one of those virtual portions is no longer available, it can cause issues.

In terms of stability, it is stable, but we have a regular update program because of the security vulnerabilities, meaning bugs. So it is an ongoing thing maintaining them.

It's a bit of an overhead at the moment.

Thomas Hejula

Senior IT Engineer at Lumeris

It seems very stable. I've had no problems with stability at all. It's been rock solid, from the perspective of staying in line and working as expected.

I did individual testing. We were doing very small tests to start, 25 megabits. So, I was driving close to 25 megabits through it. Memory and CPU, I thought might be a bit of a concern, but overall it seemed good. It was doing what I needed it to do, and doing it well, so I didn't notice anything in my traffic.

F5 BIG-IP Local Traffic Manager (LTM) is very stable.

We are a broadcast company. We have streaming services running behind this box. This streaming service has been released, with 19 to 20 streams. We haven't received any complaints about these streams since the streaming service was deployed behind F5. Despite the fact that these streams consume a lot of bandwidth and have millions of sessions. We haven't received many complaints about them.

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.

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.

Georges Samaha

I have not encountered any stability issues. It is a very stable product, even in big, high-load deployments. What I mean is that all F5 Hardware appliances are very stable and does not cause any performance degradation or failure when it has a high load (Of course a supported load).

We have deployment for different modules of F5 (LTM, ASM, CGNAT...) in Data Centers and in Telco's Public network, and we have never heard any complaints or of issues from our clients regarding the performance. - no packet drops, delays or disconnections.

It is a stable product. It runs on TMOS, traffic management operating system. This is very stable.

If they see that an upgrade required, they provide you the release and they provide you the release notes, so you can upgrade your TMOS version and at any time. You can also open a case and they can guide you on how to upgrade your TMOS version.

They also keep an eye on vulnerability. If there is a bug or any sort of vulnerability in their operating system, they will immediately release an update. So the product is so much more stable compared to any load balancers on the planet at the moment.

Unfortunately, we faced hardware failures and a lot of other problems, as well.

With the hardware failure problem, we faced a management problem via the GUI. We could only manage the device through the CLI. The issue was caused by a firmware bug.

In addition, health check statistics like CPU and memory utilization were not correct.

It is F5’s responsibility to solve those problems, and I don’t know how they can release firmware with such bugs to their customers.
