What is our primary use case?
We are a solution provider and F5 DNS Delivery is one of the products that we implement for our customers. This product is normally deployed for high application availability. That means we use the local traffic manager module the most. The DNS module is used for global server load-balancing and fail-over across data centers.
What needs improvement?
The messaging between NGINX and F5 should be simplified. When I do presentations to customers, they sometimes are confused about this issue. It is not clear where NGINX gets into the network.
I would like to see deeper integration with VMware in the sense that F5 compliments VMware, in the context of application availability. VMware has the Site Recovery Manager that looks at the virtual machine side of things. If there's deep integration with VMware, where F5 is able to figure out that an application is impaired and it wants to failover, it should be able to tell VMware to trigger that process.
Better pricing for this product would make it more competitive on the market.
For how long have I used the solution?
We have been using F5 DNS Delivery for three years.
What do I think about the scalability of the solution?
This product is highly scalable, especially given the fact that you are not confined to one particular port speed. You can upgrade as your traffic grows using different transceivers.
We have customers in several countries. In Botswana, we have between 27 and 35 clients. In Zimbabwe, we have close to 60, and in Zambia, there are fewer than 15.
How are customer service and technical support?
F5 technical support is quite good and they follow up if there are any issues. F5 support is available even before the deployment, right from the pre-sales stage to the deployment itself, as well as after-sales support.
Which solution did I use previously and why did I switch?
I have also worked with Kemp load balancers and they don't even come close to F5.
How was the initial setup?
The initial setup is straightforward. Once I have all of the information required in order to deploy, it takes one day to complete.
For my customers, I am deploying the current version, which is 16. For others, we haven't upgraded them. I'm simply patching the areas necessarily as identified by F5.
What about the implementation team?
We are the system integrator and handle the deployment for our customers.
What's my experience with pricing, setup cost, and licensing?
This product is quite pricey but if you compare the feature set and its compatibility with similar products on the market, you would understand why it's that price. Licensing is either perpetual or subscription-based, depending on the modules that you want.
What other advice do I have?
We're doing a campaign now to question our customers about business resilience using the F5 product. Most customers have invested in business continuity but sometimes they find that what they have done doesn't conform to their own business continuity plans. We go into this type of environment and introduce F5 to ensure that their continuity plans are on point.
In summary, this is a good product and I recommend it. That said, no product is perfect.
I would rate this solution a nine out of ten.
