KACE Product Support

well depending on your needs it may be a good idea to go to a cloud provider.

Pro: you have "full control" over the tenant and have console access (no backend access)
Con: you need to make sure that it is configured correctly by yourself and that it is avaible

No matter if you have a self hosted, a Kace as a Service or a cloud image you can make it always public facing.

The "cons" side of the argument may be cost, bear in mind you are paying for your KACE license, support and maintenance ongoing and you will also have to pay for the monthly cost of hosting your box in the cloud. At the moment the options look limited, so you can take KAAS, but you are fully responsible for backups and data and the costs are a little higher than buying the license outright. You can of course host in Azure, but that will introduce additional costs on to your maintenance and license. Alternatively you could also seek out a managed service provider who could provide KACE as a managed service, which is an option that is used in the Nordics for example.

With cloud hosted solutions you do also usually have the choice to set up the SMA with a direct VPN link to your environment if you want to keep everything "internal", or as Nico says just make the box externally facing and adjust the agents so they will check in from anywhere as long as they are connected to the internet, which is great for managing home workers.

Basically it depends on how big your budget is ;o)
