Reduces site failures, easy to manage from a single pane of glass, and the support is good

Pros and Cons

  • "The DNS Load Balancer makes it so that I don't have to worry about site failures."
  • "We experienced a brief period of instability."

What is our primary use case?

We use our devices as virtual load balancers for Exchange 2016, primarily.

We have two sites with two LMs at each site in clusters. We also use the devices as global DNS services and reverse proxy/authentication servers for our external users.

Our services are primarily Microsoft products being served. These include Exchange, SharePoint, CRM Dynamics, Skype, and ADFS. We are also looking at implementing websites in the future as required.

SSL offloading is enabled. Our devices are set up in the network as well as the DMZ.

How has it helped my organization?

With Kemp, I have been able to implement a global DNS load balancer between two sites for internal and external users with our existing Exchange DAG setup. This has made DR and BCP much easier to manage.

Our previous setup used Microsoft's TMG solution, and when that went end of life we needed to figure out a replacement. Being able to use load balancing, SSL offloading, and Edge Security Packages, all in one service, made my life much easier to manage from a day to day and single pane of glass perspective.

What is most valuable?

ESP gives us peace of mind because it has taken over from Microsoft's Threat Management Gateway (reverse proxy) solution. It also alerts us if there are attempted security breaches so that we can be sure we are safe.

The DNS Load Balancer makes it so that I don't have to worry about site failures. As it manages both our external DNS and internal DNS queries, we can failover to the individual sites as required. This is true for site failures as well as planned maintenance. 

We also use the Kemp 360 Vision, which monitors our services from an external perspective and alerts us via SMS and email, so I know if things go down. 

What needs improvement?

We experienced a brief period of instability.

For how long have I used the solution?

We have been using Kemp LoadMaster for six years.

What do I think about the stability of the solution?

I have only had an issue with the solution once in terms of stability. The issue was not an end user-visible issue, and upgrading the O/S fixed the issue right away.

What do I think about the scalability of the solution?

I beleive it's scalable because I can always upgrade my licensing to a unit that handles more requests. 

How are customer service and technical support?

Service is great, easy to work with, and always responsive.

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

Prior to Kemp LoadMaster, we used end-of-life products from Microsoft.

How was the initial setup?

The initial setup is straightforward, due to Kemp's support services and available templates and documentation.

What about the implementation team?

We completed the setup in-house.

What was our ROI?

I believe it is high due to the many services that the solution has been able to provide.

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

From a cost perspective, Kemp is very competitive and is not hard to justify by any means.

Which other solutions did I evaluate?

We looked at Citrix Netscaler as well as a solution by A10 Networks.

What other advice do I have?

My advice is to use Kemp's support to help with the initial setup. It is included in the initial cost and it makes sure that best practices are used. Keep up with the support because it's worth it.

I am currently happy with everything.

Which deployment model are you using for this solution?

Flexible with good technical support and horizontal scalability

Pros and Cons

  • "The product is quite flexible."
  • "The cost of the solution is pretty high. It would be ideal if it was more reasonable."

What is our primary use case?

The F5 is something we purchased for another project that has not been turned on just yet.

What is most valuable?

The solution is very powerful.

The product is quite flexible. 

The horizontal scalability that is on offer is very good as well.

What needs improvement?

I would like to see some better documentation focused on our website and better search criteria. That's probably the best way to say that there needs to help with research.

The cost of the solution is pretty high. It would be ideal if it was more reasonable.

For how long have I used the solution?

We were originally supposed to launch this project for a client, however, that hasn't materialized yet.

What do I think about the scalability of the solution?

While we never really got around to scaling the solution just yet, there is horizontal scalability that is on offer that seems very good.

This is being deployed in a service provider environment. Therefore, it'll be impactful to all of our customers. However, I would say as far as internal support users, we have a team of probably ten that'll be supporting this product once it's launched in production.

How are customer service and technical support?

In terms of technical support, so far it has been pretty good. That said, it's more to set up the solution versus actual production support. They're not helping us deal with bugs or glitches, they've just been helping us with a rather complex implementation. We've been satisfied with their assistance in that sense. They seem knowledgeable and responsive.

How was the initial setup?

The initial setup is largely complex. However, we had a lot of help from their internal sales team or support team has been important in terms of working around the difficulties.

We have a staff of ten that are handling deployment and maintenance. They're not dedicated just to this product, however. They support our overall service provider architecture.

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

The cost is quite high. The long-term support in particular is quite high.

Customers need to be aware that each feature is licensable, which allows costs to accrue.

What other advice do I have?

We're just a customer. We don't have a business relationship with F5.

The F5 is something we purchased for another project that has not yet been turned up. That said, the experience I've had with F5 has been very positive, specifically working directly with their corporate sales engineering team. 

Overall, I'd rate the solution eight out of ten. If it wasn't for the high cost of the product, I might rate it a bit higher.

I would advise those considering the solution to explore all options. Specifically, the total cost of ownership. It can be lower with some other vendors. A10 is oftentimes a lower cost of ownership. One challenge with F5 is everything is a licensable feature. Whereas something like an A10 is not. You see the same challenges with a Cisco type of device as well, however, it's in a different arena, with different products.

Easy to use, good performance, and the SSL upload capability is helpful

Pros and Cons

  • "The most valuable feature is the SSL upload."
  • "The pricing for this solution should be reduced so that it can be more competitive."

What is our primary use case?

We are a solution provider and this is one of the products that we deploy for our customers. I have deployed VIPRON six different times so far. Our customers are in the banking industry.

Our clients primarily use this solution in core banking for handling card-based transactions.

What is most valuable?

The most valuable feature is the SSL upload. It is very useful.

The performance is good.

It is easy to use and it doesn't take much experience.

Customization is very good.

What needs improvement?

The pricing for this solution should be reduced so that it can be more competitive.

For how long have I used the solution?

I have been working with F5 VIPRON since 2015.

What do I think about the stability of the solution?

The stability of F5 is great.

What do I think about the scalability of the solution?

This solution is for big clients in industries such as banking, finance, and the stock market. Small companies do not use it at all.

How are customer service and technical support?

Technical support from F5 is good, and the community support is very good as well. You can search the community for issues, documentation, deployment models, and so forth. It is very useful.

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

I have also worked with the Citrix application delivery controller (ADC), and am familiar with A10. I think that F5 and Citrix are at the top of this market.

How was the initial setup?

This product is quite easy to deploy. The only thing that you need expertise in is Azure so that you can fully integrate it into the system.

The length of time required for deployment depends on the environment. For large systems, it will take three or four weeks to deploy. Smaller systems will take perhaps two.

Three teams contribute to the deployment including the F5 engineer, who is familiar with the device, the F5 application team, and the infrastructure team. At least four or five people are involved. 

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

The price of this solution can be quite high, and it is determined based on the size that is required for the environment.

What other advice do I have?

The biggest lesson that I have learned from working with this product is that the sizing must be correct, which is because of the cost of the device and the license. We sometimes have problems because pre-sales engineers will suggest a lower model to save on costs, but this results in substandard performance that cannot handle the level of throughput and concurrent connections. It is very important to have the sizing assessed properly.

Overall, I think that the product is very good and our only complaint is about the pricing.

I would rate this solution an eight out of ten.

Which deployment model are you using for this solution?
