Citrix Workspace includes several components that can replace or integrate with the traditional Citrix infrastructure components, such as:
Citrix Cloud Services, which provide management and orchestration capabilities for Citrix Workspace, such as Citrix Virtual Apps and Desktops service, Citrix Gateway service, Citrix Endpoint Management service, etc.
Citrix Workspace app, which is a client software that enables users to access their apps and desktops from any device.
Citrix Cloud Connectors, which are software agents that establish a secure connection between Citrix Cloud Services and the on-premises or cloud-based resources, such as Active Directory, hypervisors, VDAs, etc.
According to Citrix documentation2, an administrator who chooses to move all of the backend Citrix infrastructure to be managed as a service by Citrix can use the following components:
Citrix Virtual Apps and Desktops service, which replaces the Citrix Delivery Controllers and provides centralized management and delivery of virtual apps and desktops.
Citrix Studio, which is still available as a web-based console for configuring and managing the virtual apps and desktops environment.
Citrix Gateway service, which replaces the Citrix NetScaler and provides secure remote access to virtual apps and desktops through a single URL.
Citrix StoreFront, which is still available as an optional component for providing users with self-service access to their apps and desktops through a web portal or native receiver.
