Minimal maintenance is required because it is a virtual appliance, and everything is preconfigured.

We have a virtual appliance. We chose the virtual appliance because we were already using a virtual machine infrastructure, so it was easy for us. Our implementation is not complex. We do not have a lot of regulations. It does not matter if we lose connectivity. It is not the end of the world, so for us, a virtual appliance was good enough. It was easier to implement. We do not need to rely on physical devices.

We are using the virtual appliance because we already have a virtual environment. The only on-prem setup we have are the physical servers that run a hypervisor. We like to have everything virtual. We can also secure a virtual appliance in a different way compared to the physical appliance. With a physical appliance, if something happens, we have to get hold of the vendor and sort out how fast they can ship a replacement, whereas we can deploy a virtual appliance instantly and get it up and running if there is a problem.
