Good depiction of profiles, very easy to set up, and very stable

Pros and Cons

  • "iRules are very valuable. In addition to that, the way profiles are depicted by the LTM is also very good."
  • "A lot of functions that are attributed to iRules can actually be simple profile changes. iRules do have a certain performance impact. Therefore, instead of writing simple iRules, they can create certain profiles for classes that will perform the same function."

What is most valuable?

iRules are very valuable. In addition to that, the way profiles are depicted by the LTM is also very good.

What needs improvement?

A lot of functions that are attributed to iRules can actually be simple profile changes. iRules do have a certain performance impact. Therefore, instead of writing simple iRules, they can create certain profiles for classes that will perform the same function.

Its scalability and pricing can also be improved.

For how long have I used the solution?

I have been using this solution for more than 12 years. We are currently using version 15.1.2. The latest one is 16.0, but we are still evaluating it.

What do I think about the stability of the solution?

It is very stable.

What do I think about the scalability of the solution?

It is not scalable. It is a licensed product. They are coming up with some scalable options, but for existing products, throughput is limited. Currently, if you have a 200 Mbps license, then it can go to a maximum of 200 Mbps. If you want it to go further than that, then you have to buy a new license.

How are customer service and technical support?

Their technical support is good.

Which solution did I use previously and why did I switch?

I've been working for 12 years, and F5 was the first LTM product. In addition to F5, I've also worked on Citrix NetScaler, Load Balancer, Kemp, and Cisco ACE (no longer in service). I prefer F5 over all of them.

How was the initial setup?

Its initial setup is very easy. The biggest advantage that F5 has is that its initial setup is very simple.

What's my experience with pricing, setup cost, and licensing?

It is quite expensive as a product. Because it is very stable, it is also expensive.

What other advice do I have?

For mission-critical applications, you can trust F5 with any of your load balancing functions. However, if you have a UAT environment or a test setup, it won't be suitable because it is a pricey product. You can then go for an open-source product or any software with load balancers. VMware has recently come up with AVI load balancers.

I would rate F5 BIG-IP Local Traffic Manager (LTM) an eight out of 10.

Straightforward, stable, scalable, and really good for load balancing

Pros and Cons

  • "The web application firewall feature is the most valuable and useful feature. It is a leading industry product when it comes to load balancing. Its user interface is very simple. There isn't a steep learning curve. When we initiate someone to F5, they start using it quickly."
  • "Its price can be better. It is a bit expensive."

What is our primary use case?

We are a reseller of F5, but we haven't had many projects that we've deployed with F5. In terms of use cases, it is used when clients have web servers, and they are hosting on their own infrastructure. When they have web applications that are publicly visible, they use F5 to balance that incoming traffic for their web servers.

What is most valuable?

The web application firewall feature is the most valuable and useful feature. It is a leading industry product when it comes to load balancing.

Its user interface is very simple. There isn't a steep learning curve. When we initiate someone to F5, they start using it quickly.

What needs improvement?

Its price can be better. It is a bit expensive.

For how long have I used the solution?

I have been using this solution for the last five years.

What do I think about the stability of the solution?

It is very stable.

What do I think about the scalability of the solution?

It is very scalable. 

How are customer service and technical support?

I never had a case that required technical support.

How was the initial setup?

It is very easy to set up. It is not a complicated product. The deployment duration depends on the architecture that you're deploying, but it usually doesn't take much time.

What about the implementation team?

The number of people required for its deployment depends on the size of the deployment. For a very big deployment, you need less than three people. For a fairly normal or standard deployment, just one person would be fine.

What's my experience with pricing, setup cost, and licensing?

It is a bit expensive product. Kemp Loadmaster is much cheaper than F5. 

Its licensing is on a yearly basis. It can be for one year or three years.

What other advice do I have?

I would recommend this solution. It is a really good solution. It is fairly straightforward, and it does what it is meant to do.

I would rate F5 BIG-IP a nine out of ten. In terms of features, it is good, but its price can be better.

Stable solution but could improve its integration in future releases

Pros and Cons

  • "In terms of stability, it is stable."
  • "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."

What is our primary use case?

In terms of our primary use cases - all our web services, our main web portals, and our TV service sit behind the F5, so any customer would have to traverse our F5 for the services at the back of it.

It serves our backend and front end services.

What needs improvement?

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.

For how long have I used the solution?

I have been using F5 BIG-IP Local Traffic Manager for about five years now.

What do I think about the stability of the solution?

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.

What do I think about the scalability of the solution?

In terms of how many users we have using it, for the end user, all our customers go through the F5, so they are using it in terms of service. In terms of our engineers and how many people use it, that depends. If you're deploying it or you're in operations, like I am, there are hundreds of engineers and internal users.

How are customer service and technical support?

We have weekly calls with F5 directly. We used to go through a third party, but now we go directly to F5 for our support.

What's my experience with pricing, setup cost, and licensing?

When you buy it you have a license bundle which I think you have to renew every year or every couple of years.

What other advice do I have?

On a scale of one to ten, I would probably give F5 BIG-IP Local Traffic Manager a six.

I would give it a warm recommendation, I would not give it a glowing recommendation. I'd give it a warm, "Tread with caution."

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?

What needs improvement?

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.

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.

Good bandwidth optimization and video streaming capabilities, awesome scalability, and fast support

Pros and Cons

  • "Bandwidth optimization and capacity awareness of the bandwidth are valuable features. Its video streaming capabilities are also very useful."
  • "The user experience for dashboards and reports can be improved. They should make dashboards and the reporting system easier for users. They need to add more reports to the dashboard. Currently, for complicated reports, I have to do the customization. It should have more integration with network firewalls to be able to gather all the information required for traffic management."

What is our primary use case?

There are many use cases. It is mainly used for local traffic management. It can also be used as an advanced firewall for an application or as a VPN policy manager.

We have cloud, on-premise, and hybrid deployments.

What is most valuable?

Bandwidth optimization and capacity awareness of the bandwidth are valuable features. Its video streaming capabilities are also very useful.

What needs improvement?

The user experience for dashboards and reports can be improved. They should make dashboards and the reporting system easier for users. They need to add more reports to the dashboard. Currently, for complicated reports, I have to do the customization.

It should have more integration with network firewalls to be able to gather all the information required for traffic management.

For how long have I used the solution?

We were their partners for five years, and since last year, we are officially their distributor.

What do I think about the scalability of the solution?

It is really awesome. You can scale from one or two servers to hundreds of servers. They have all the modules that a customer needs. You can go for on-premise or cloud deployment. You can have whatever you need.

Our clients are medium and large businesses.

How are customer service and technical support?

They have 24/7 support. You can open a ticket directly in F5, and there is no need to use another system.

They reply very fast. They usually get back within four hours, and sometimes, you get a response immediately. They have four-tier system support.

How was the initial setup?

Its initial setup is straightforward. It is just like a wizard and not complex. It takes only a few seconds.

What's my experience with pricing, setup cost, and licensing?

You can buy it on a yearly basis, or you can go for a subscription. For on-premise boxes, it is just the RMA.

What other advice do I have?

I would rate F5 Traffic Management Operating System a nine out of ten.

Good customization with knowledgeable and responsive support

Pros and Cons

  • "The most valuable feature is customization."
  • "I would like to see better integration."

What is our primary use case?

We are using this solution as a load balancer and reverse proxy.

What is most valuable?

The most valuable feature is customization.

What needs improvement?

We are currently using BIG-IP and NetScaler and we wanted to have just one technology. We will be replacing F5 in March.

NetScaler is primarily used for Citrix purposes and BIG-IP is being used as a reverse proxy for our other applications.  We would like to manage it easily with one technology.

I would like to see better integration. I can remember when we were implementing ADFS, we had some challenges.

There is not a lot of documentation available where you can refer to and configure any new technologies.

For how long have I used the solution?

I have been working with F5 BIG-IP for approximately seven years but our organization has been using this solution for 13 years.

What do I think about the stability of the solution?

This solution is stable. We have not experienced any issues.

What do I think about the scalability of the solution?

It's a scalable solution and we have not had any limitations. We have approximately 3,000 users.

How are customer service and technical support?

Technical support is very good in terms of their technical knowledge and assistance.

We have had contact with both F5 and Citrix. 

F5 has a good technical team who can assist and understand the problem and respond quickly. However, Citrix has been a challenge for us.

How was the initial setup?

When we were setting up for Azure we had some challenges.

We have an internal team of two for maintenance and reporting.

What other advice do I have?

I would definitely recommend this solution to others who are interested in using it.

I need to have a deeper understanding of F5 technology.

I would rate this solution an eight out of ten.

Is stable, scalable, and easy to install

Pros and Cons

  • "Currently, it's distributing the load perfectly, as per my understanding of our requirements."
  • "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."

What is most valuable?

As an IT developer, mostly I use load balancing for the traffic. Currently, it's distributing the load perfectly, as per my understanding of our requirements.

It's definitely scalable and is stable as well.

The initial setup is not complex, and the technical support is fine.

What needs improvement?

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.

So, I think they should improve in terms of security because nowadays, most organizations try to build their infrastructure on public cloud.

More documentation should be uploaded because very limited documentation is available on the internet. It will also help us to understand the system before purchasing the product.

For how long have I used the solution?

I've been using this solution for two years.

What do I think about the stability of the solution?

It's a stable solution.

What do I think about the scalability of the solution?

It's definitely scalable. It's a distributed architecture and micro services, so it's scalable. In fact, we are planning to increase usage and scale horizontally.

How are customer service and technical support?

I don't have any issues with respect to technical support; it has been fine.

How was the initial setup?

The initial setup is not complex. 

What other advice do I have?

If you have your own data center, then you can use F5 BIG-IP Local Traffic Manager (LTM). I don't see any issues because they have been in the industry for a long time, and F5 BIG-IP Local Traffic Manager (LTM) is very stable.

I would rate this solution at eight on a scale from one to ten.
