We use Cisco SD-WAN for a VPN, and we create the DNS in Fortinet. We have used this solution for data centers and failover tests for disaster recovery.
It is really easy to deploy and use. It is also easy to use for failovers and designing solutions.
The rollout is really quick. It is easy to adjust and roll out.
I have been using Cisco SD-WAN for five or six years.
It is as stable as your lines are. We mostly have fiber connections, and it is really stable and performing well. I once had a problem with a power unit, but I have never experienced any downtime.
We have contacted them. All engineers were experienced enough to support us. We had a special team from Cisco.
The initial setup was straightforward. The design takes longer than the implementation. You have to know your layer 3, but it can also define layer 2 or layer 1. It is really a great tool.
I used a consultant for the implementation. I am an architect, and I only design the solution. I discuss the solution with the network engineer and then roll it out with the help of the network engineer and the project manager.
It is much cheaper than other solutions. Most of our clients are the top 500 companies, and they all have a corporate contract.
I would recommend this solution. It is a great solution, and it is already defined. It is more suitable for medium and large enterprises operating in lots of regions and countries. For smaller organizations, you can use a normal business DSL solution.
I would advise doing a VR test to make sure that all settings are correct. We have had issues where the configuration or IP spoofing on the network was not so good. You also need to know the number of tenants that you need. You can set it up on paper, but if you don't test it, you would never know that it is working.
I would rate Cisco SD-WAN a nine out of ten. It is the best solution that I ever had, but there might be something better than this in the future.
