(no major updates with 2016)System Center is based on the .NET frame work. The primary administrator interfaces are not browser-based (like e.g. the new vSphere web client attempts to achieve). There are however web based components for some of the SC products and functions like the Service Manager Self Service Portal (SSP) or the Operations Manager Web Console. Please note that the web based VMM Self Service Portal has been removed with SC SP1. You can implement Windows Azure Pack to deploy virtual machines from a Portal.
