On-Premises vs Cloud

Refers to where the hardware controlling your VoIP service is housed and who is responsible for managing and maintaining it. With an on-premises solution, you are responsible for the hardware and the service costs. Hardware is literally housed on your premises, in your office. In a hosted environment, your service provider is responsible for all the operating costs and you simply pay for the service you use. The hardware that supports cloud services is usually housed in datacenters and delivered via the cloud.
