Amazon WorkSpaces Core is a set of VDI APIs for third-party software. WorkSpaces Core enables customers and partners to build customized VDI solutions using purpose-built compute instances optimized for virtual desktops. This means that vendors such as Citrix and VMware can offer VDI and DaaS products that will use AWS infrastructure rather than on-prem virtualized options such as VMware vSphere/ESXi hosts or XenServer.
Amazon WorkSpaces is an all-inclusive virtual desktop service. Amazon WorkSpaces Core does not include the virtual desktop infrastructure (VDI) software and management layer.
