Explanation
According to the Citrix Virtual Apps and Desktops service documentation1, the Citrix Virtual Apps and Desktops service allows administrators to manage on-premises resources from the cloud, while providing users with secure access to those resources from any device. The Citrix Gateway service2 provides secure remote access to the on-premises resources through the Citrix Cloud Connector. The Citrix Provisioning service3 enables administrators to stream a single desktop image to multiple virtual machines, reducing storage and maintenance costs.
