What is our primary use case?
My main use case for F5 BIG-IP Local Traffic Manager (LTM) is placing our applications on F5 and the backend servers on the pool. We also regularly renew SSL certificates before they expire, usually one month in advance. This is the primary use with F5 BIG-IP Local Traffic Manager (LTM). We have a couple of data centers, and each has its own F5 setup.
For F5 BIG-IP Local Traffic Manager (LTM), we usually work with F5 BIG-IP. Earlier, I think we were working on the I-series, and currently, we are working on the R-series. The setup in our environment is configured as high availability, meaning there are two F5s working as HA. Stryker usually works for load balancing. We have backend servers, which we call pool members, and we create a VIP to do the load balancing. It depends on user and application requirements regarding how they want to load balance and how many servers they provide. Accordingly, we set up the VIP and pool and select the appropriate load balancing method to distribute traffic across multiple servers. Mostly, we use the least connection method, although it varies based on the need. F5 BIG-IP Local Traffic Manager (LTM) has a setup with HA failover, so during upgrades, we do a failover. Ideally, we activate the standby first before upgrading the other leg of HA. This setup helps us optimize traffic distribution across multiple servers.
What is most valuable?
F5 BIG-IP Local Traffic Manager (LTM) offers effective load balancing methods that help distribute traffic across our servers, whether we have two or several. This load balancing feature stands out as it is the fundamental work we do with F5 BIG-IP Local Traffic Manager (LTM). While I recognize there are many features, such as iRules, which I have not explored yet, we primarily work on VIPs, pool members, and traffic distribution.
The load balancing algorithms' flexibility makes them very useful for our team, enabling us to choose different servers and manage load effectively. We use various methods based on user or application requirements, making the algorithms set up by F5 in the backend quite helpful.
F5 BIG-IP Local Traffic Manager (LTM) positively impacts our organization primarily through its load balancing capabilities. We avoid traffic overload on individual servers by placing backend servers behind F5 BIG-IP Local Traffic Manager (LTM) VIP. This load balancing helps us manage traffic effectively. Since the configuration of the I-series, we have had smooth performance, and with the recent migration to the R-series, it is working faster than before, providing positive outcomes for our operations. Since moving to the R-series, I notice improved performance; it is user-friendly and handles traffic efficiently. The upgrading process is different as we create tenants and a main host. R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.
What needs improvement?
F5 BIG-IP Local Traffic Manager (LTM) could improve file upload speeds when opening cases and attaching files; sometimes, downloading files like QKView takes time, depending on size. I expect faster resolutions when providing contact numbers while raising cases, as other companies typically do.
For how long have I used the solution?
I have been working at Stryker for three years. Earlier I was at Ericsson, where I worked for three years as well. I have been working in this domain for six years. Since I joined Stryker, I have been using F5 BIG-IP Local Traffic Manager (LTM) for three years.
What do I think about the stability of the solution?
F5 BIG-IP Local Traffic Manager (LTM) is very stable.
What do I think about the scalability of the solution?
In terms of scalability, F5 BIG-IP Local Traffic Manager (LTM) is good.
How are customer service and support?
Customer support is quite good but could be faster. While I have not faced any challenges so far, I hope for quicker resolutions in the future.
Which solution did I use previously and why did I switch?
We have never used any other solutions before F5 BIG-IP Local Traffic Manager (LTM), as we have consistently relied on it since our initial setup. F5 BIG-IP Local Traffic Manager (LTM) is truly reliable, and we have not considered any alternatives for our load balancing needs.
What other advice do I have?
I would advise others to try using the more advanced R-series model, which offers greater capacity and capabilities. F5 BIG-IP Local Traffic Manager (LTM) is a well-known product, and everyone recognizes its features and functionality, so you can confidently recommend it without needing lengthy introductions.
I have heard of features such as X-Map or X-Connect, but I have not had the chance to work on them. Sometimes users request details about how many users hit the VIP and their IPs, but I am unsure about that feature. I want to learn more so I can provide those details when needed. Currently, we only have static information on the pool members.
I would rate this product a ten out of ten.
