How was the initial setup?
The setup is straightforward for advanced users and administrators. If you are a beginner the setup can be quite difficult, especially with the partitioning phase. The basic installation on the premises only takes ten minutes. If you are installing on the cloud there are a few extra steps that can take up to 20 minutes such as the provider's security, networking, public IP addresses, and some rules that have to be configured before the system is ready.

The implementation was completed in-house.

For anyone interested in trying the solution there is a lot of information and support that is freely available online.
Which deployment model are you using for this solution?

We do not have plans to increase usage.
