There are a lot of good things this solution has, including:

The LTM module helps to load balance the traffic among the internal web server in our case using round robin and least connection method.

The ASM module prevents web attacks and protects our web servers.

The irule feature is used to write these irules to redirect the traffic or sometimes prevent automated attacks such as through BOTs where the distinction between real and fake users becomes increasingly tricky.

Its virtual servers have the option to configure other things to increase the speed of serving requests like the use of a persistence profile.

• iRules
• Simplicity

I was able to simply and quickly set up the WAF rules and security, and also set up easily complex policies and rules which gave me some great features to redirect. So, I had to integrate API Gateway into our WAF, because we're a healthcare company, and we have to maintain security. Therefore, they didn't want to have public endpoints that had not been inspected. The policy features inside the WAF rules were really easy for me to set up. What I thought was going to take me two months, I had done in about two weeks. Between Googling and F5 having great information, so instead of using traditional iRules, I used a policy thing that they recommended. It was much simpler and cleaner, and seemed to execute faster. It was a great feature.

The configuration and implementation of what I thought I was going to have to do was a lot simpler than I expected it to be. That was a plus.

The most valuable feature of F5 BIG-IP Local Traffic Manager is that it allows you to manipulate things. Now, manipulation here is in the sense that you can do whatever you want to do in the solution using something called iRule, which is a programming interface for F5. So, this is something I find to be extremely useful when compared to other vendors.

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.

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.

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.

iRule: It's a great feature that helped us multiple times have an advantage over competition (during PoCs) performing some traffic control/management functions that are not supported out of the box. Use Case: One client was deploying a new web app, where video/chat Traffic is configured over the SOCKS protocol. We used iRule to disable the WAF Inspection when a SOCKS protocol packet passed through (because it is not supported), and enable the WAF Inspection for all other URLs on the same Web page. (No other vendor in our region was able to provide that.)

Appliance Performance: One of the main advantages we always have over competition is in hardware performance, where the smallest F5 appliances compete with competitors’ medium to high-end appliances, while high-end devices can sit in the datacenter without risking performance degradation.

The most valuable feature is the F5 LTM (Local Traffic Manager). This is the part of the product most organisations will be using most. It provides the core functionality to be able to load balance services and the means and the intelligence to be able to load balance based on advanced logic, e.g., TCL scripting.

The F5 GTM/BIGIP DNS (Global Traffic Manager) is another valuable feature. This feature allows for DNS load balancing, which means that high availability and load sharing can be done across services locally, as well as across datacenters with advanced capabilities.

We had a problem where customers were doing transactions in our system, pulling health records, and the system had to be shut down for maintenance. Unfortunately, we wouldn't know that the system was being shut down, and we would lose that information. Then, the customer would get upset.

Using the F5, we were able to build rules to detect that the shutdown was occurring, then begin to route people elsewhere, so we didn't have any outages or downtime. This made customers a lot happier, and it made us a lot happier.

We like the capability to combine the content switching with the intrusion prevention and adding the security roles, so we can expose certain sub-pieces outside without exposing everything.

We are using the Big-IP, LTM, ASM, and GTM modules.

• The Local Traffic Manager (LTM) provides a simple low balance and SSL decryption, in addition to some TCP parameters, for incoming and outgoing traffic to redirect appropriate traffic patterns to appropriate servers. 
• We are using Application Security Manager (ASM) as a web application firewall, where there is a security signature to avoid a web level breach. 
• We are using global traffic manager (GTM). Its main use cases is for application firewall modules, therefore we are not using it yet, but we are going to implement it for DDoS protection on some of our web services.

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.

The main reason that we suggest this product to our clients is the great integration with other security tools, such as IBM Guardium. 

This product is very user-friendly, which is good for customers who have an implementation done by a partner but want to handle administration in-house.

All of the functionality can be achieved from one console.

Even on Hyper-V or a VMware appliance, the performance is very good when you use it as a proxy or a web application.

The documentation is very good.

It has so many features. First of all, it has a full proxy architecture, it has multiple modules. The best feature is the WAF, the web application firewall module. It also has cashing type capabilities. It has all kinds of load-balancing algorithms based on your IT requirements.

So the WAF and load balancing. Both are core features of BIG-IP.

In every environment, you have a Web application firewall, you have internet firewalls. Then, traffic comes into your datacenter so that you have datacenter firewalls. F5 has everything.

It provides first-tier firewalling, for you application. And it provides server load-balancing, it provides optimization, and it provides a proxy feature, where your users cannot directly access your server. It acts as a fully proxy architecture. It has client-side and server-side connections, both, and they're separate.

It also has an AVR feature: application, visibility, and recording. It's good for customers looking for what is actually happening in their network and where the latency is. If I'm using iDirect, the bank branch is connecting to my core banking application, but if the clients are finding that the application is slow, it has TCP  LAN and WAN optimization features. It has has caching.

iRules are so helpful in meeting our complex application’s architecture in case of routing. The requests have to be routed according to the cookies and headers of the host name itself. And also we can log the details, which helps us a lot in troubleshooting.

Using the “repeat” option when creating multiple virtual servers, we are able to create as many virtual IPs as we can as we go. This reduces a lot of configuration time.

It is very intuitive, easy to deploy, and manage.

The solution's capabilities has been most instrumental in supporting our customers. I find it reliable. Once it is configured, and up and running, then there usually is no downtime.

In terms of performance, we have seen a drastic difference without F5, then with it. If you run the same application from users to the server when there wasn't F5, there were delays. With F5, users can see a remarkable performance difference from a qualitative sense.
