"The solution is easy to install. It's a straightforward process.""The capability is at a seven or eight out of ten.""There is a lot of documentation available.""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.""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.""NetFlow balancing and traffic balancing are good features.""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.""The scalability of the solution depends on the sizing of the network. Generally, the scalability is quite good."

More F5 BIG-IP Local Traffic Manager (LTM) Pros →

"An area for improvement would be the difficulty in finding information about standard licensing costs over the internet. They should provide some reference prices on the net to be quickly referred to.""The only thing customers told me that could be improved is that they would like to be able to purchase and receive the products in one box, rather than two boxes. This is something related to marketing, though.""The technical support could be improved. They do not respond or assist customers in a timely manner.""Citrix ADC can improve if it provides a more user-friendly interface and clear working protocols. Citrix is not working with classic RFC, it is working with Citrix RFC, which is not common in the world. If engineers of Citrix can provide us with more information on working with the classic IP networks it would be a benefit.""The solution can improve their support and send tickets directly to a Citrix ADC engineer in order to avoid having to escalate each support call.""Overall the price of Citrix ADC could be more competitive.""The solution could be more secure.""Native integration needs to be improved. You cannot build ISE codes natively. For DevOps, integration would be very helpful because it would be a lot simpler from an operational standpoint."

More Citrix NetScaler Cons →

"In terms of what could be improved, I would expect more integration with different platforms and more integration with the backend systems. Additionally, in the next release, I would like a more secure version.""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.""I'm not very sure about the security with F5 BIG-IP Local Traffic Manager (LTM). We have our own private data center, but we are going to migrate our private data center into the Azure cloud environment. Security will then be a major concern when we migrate our own whole infrastructure to the public cloud.""F5 could improve the rule-setting capabilities in the GUI, and they need to simplify web management. For example, the menus in the Citrix GUI are easier to navigate, with a clean structure and layout.""Technical support could be faster. It's something I'd like to see them work on in the future.""An expensive solution for the minimal features we use.""There are not very many areas for improvement, but the price is high.""The solution is scalable."
