Ctos live desktop backround4/8/2023 ![]() ![]() The PortICA service – Here’s number two. ![]() It communicates with the PortICA service and the Delivery Controller exchanging ‘pre logon’ ticket data and user credentials as part of the user authentication en verification process within a virtual desktop infrastructure. the Broker service) – This is the first of the two Desktop OS based FMA services. StoreFront service – Manages your StoreFront deployment which can be managed from Studio as well.Therefore FMA services are best checked using PowerShell. Due note however, that although these alerts will tell us that something is potentially wrong, with regards to one of our primary FMA services for example, they won’t tell us what is wrong or where to look for answers. These will pop up in Studio or Director for example. Monitor service – Monitors the overall FMA architecture and produces alerts and warnings when it finds something is potentially wrong.Environment Test service – Manages tests within your XenDesktop Site, can be initiated from Studio for example.Physical machines are still optional as well, but again, you’ll use PVS instead of MCS. This is where your virtual Server and/or Desktop VM’s live. This can be either vSphere, XenServer or Hyper-V. Host service – Manages all connections between the physical hosts, the Delivery Controllers, and the underlying Hypervisor.If you need to service physical machines you will need to implement Provisioning Services. Also note that MCS is only capable of creating virtual machines, not physical. When this service is unavailable no additional virtual machines can be created. Machine Creation service – Handles the creation of new virtual machines.If this service becomes unresponsive or unavailable it won’t mean that Site management isn’t possible, it just means that no new, or existing, administrative accounts can be created or re-configured. Delegated Administration service – This one manages the configuration and administration of all delegated administrative permissions.The data itself can be stored as part of, or within, the central site database or a separate database can be created. Depending on its configuration, no Site changes are possible when its database is unreachable. Configuration Logging service – It monitors and logs all configuration changes made within a XenDesktop Site, including all Administrator activity.ID Identity service – It handles all Active Directory computer accounts related to XenApp / XenDesktop virtual and physical machines.This is one of the main reasons why the Configuration service is such an important one, it handles all inter service communication. Configuration service – All FMA services need to register with the configuration service on startup so that it knows they are all good to go.From a Desktop OS VDA point of view (Desktop service) it handles all communication from and to the Delivery Controller. From a Delivery Controller point of view it brokers new sessions, handles resource enumeration, the creation and verification of STA tickets, user validation, it handles disconnected sessions and so on and so forth. the Desktop service) – Probably the best known one. These FMA services combined will communicate with the underlying Hypervisor, the virtual machines, the DC, and be responsible for the creation of new machines, delegated administration, configuration logging, services interaction and more. Once installed and set up it consists out of ten primary services on our DC, and twelve services in total when running a virtual desktop infrastructure (VDI), with two additional services running on each of your desktop OS based VM’s. It communicates with Studio, Director, the central Site database and the VDA’s installed on the virtual and physical machines in our datacenter. The Delivery Controller as part of XenDesktop is the hart of your FMA. Let’s just call it FMA from now on and use the product technology stacks, XenApp (HSD or SBC) and XenDesktop (VDI), to indicate what will be delivered to our users. Here I’ll provide you with a rundown of all services that make up the FMA including their responsibilities and some background information. the Desktop service, and the PortICA service both live on your desktop OS based VM’s, which are then part of the FMA as well, making it twelve services in total. Let me explain, when administering a Virtual Desktop Infrastructure (VDI) for example, the Broker Service, a.k.a. The Flex Management Architecture is a service-orientated architecture, it consists out of ten, or twelve depending on your point of view, primary services in total.
