While designing the infrastructure, we are going to consider the five layer model, which will help us implement unified and standardized solutions for every use of XenApp and XenDesktop 7.6.
User layer: In this layer, we identify and define the unique user groups, the endpoints they will be using to connect, and their location
Access layer: In this layer, we define how a user group will gain access to their resources, focusing on access policies and desktop/application stores
Resource layer: This layer defines the application and data provided to each user group
Control layer: This layer defines the underlying infrastructure required to support the user accessing their resources
H ardware layer: This layer defines the physical implementation of the overall solution
This model gives us the ability to create an extremely flexible model with which user groups can have their own set of access policies and resources, which can be shared. Regardless of how the user accesses and the resource layer are defined, they all are managed by a single, integrated control layer.
