Crear una experiencia de usuario en la que los equipos puedan aprovechar todo el potencial de sus herramientas es de vital importancia para mantener a tu empresa al frente de la competencia. Aumenta la productividad con las GPU virtuales y el software NVIDIA Virtual Applications (vApps) para el streaming acelerado de aplicaciones con las soluciones de host de sesin de desktop remoto (RDSH), incluidas Citrix Virtual Apps y VMware Horizon vApps. Las vApps de NVIDIA permiten a los usuarios acceder a cualquier aplicacin de Windows a pleno rendimiento en cualquier dispositivo y en cualquier lugar.
El software NVIDIA Virtual Apps ofrece una experiencia de usuario increble para el espacio de trabajo digital, por lo que los equipos pueden usar sus aplicaciones virtualmente sin perder rendimiento o productividad. Con el uso compartido de GPU, varias mquinas virtuales que funcionan como VDA pueden funcionar con una sola GPU para data centers y as maximizar la utilizacin y la asequibilidad. Compatibles con las principales plataformas de virtualizacin de hipervisores, las vApps permiten que los administradores de data centers puedan usar las mismas herramientas de administracin para sus servidores acelerados por GPU que las que usan para el resto de su data center.
The Delivery Controller is the central management component of a site. Each site has one or more Delivery Controllers. It is installed on at least one server in the data center. For site reliability and availability, install Controllers on more than one server. If your deployment includes a hypervisor or other service, the Controller services communicate with it to:
At least one Microsoft SQL Server database is required for every site to store configuration and session information. This database stores the data collected and managed by the services that make up the Controller. Install the database within your data center, and ensure it has a persistent connection to the Controller.
The VDA is installed on each physical or virtual machine in your site that you make available to users. Those machines deliver applications or desktops. The VDA enables the machine to register with the Controller, which in turn allows the machine and the resources it is hosting to be made available to users. VDAs establish and manage the connection between the machine and the user device. VDAs also verify that a Citrix license is available for the user or session, and apply policies that are configured for the session.
The VDA communicates session information to the Broker Service in the Controller through the broker agent in the VDA. The broker agent hosts multiple plug-ins and collects real-time data. It communicates with the Controller over TCP port 80.
VDAs are available for single-session and multi-session Windows operating systems. VDAs for multi-session Windows operating systems allow multiple users to connect to the server at a time. VDAs for single-session Windows operating systems allow only one user to connect to the desktop at a time. Linux VDAs are also available.
You can manage your Citrix Virtual Apps and Desktops deployment using two management consoles: Web Studio (web-based) and Citrix Studio (Windows-based). This product documentation covers only Web Studio. For information about Citrix Studio, see Citrix Virtual Apps and Desktops 7 2212 or earlier.
Citrix Studio is the management console where you configure and manage your Citrix Virtual Apps and Desktops deployment. Citrix Studio eliminates the need for separate management consoles for managing delivery of applications and desktops. Citrix Studio provides wizards to guide you through environment setup, creating workloads to host applications and desktops, and assigning applications and desktops to users. You can also use Studio to allocate and track Citrix licenses for your site.
Director is a web-based tool that enables IT support and help desk teams to monitor an environment, troubleshoot issues before they become system-critical, and perform support tasks for end users. You can use one Director deployment to connect to and monitor multiple Citrix Virtual Apps or Citrix Virtual Desktops sites.
The hypervisor or other service hosts the virtual machines in your site. These can be the VMs you use to host applications and desktops, and VMs you use to host the Citrix Virtual Apps and Desktops components. A hypervisor is installed on a host computer dedicated entirely to running the hypervisor and hosting virtual machines.
When users connect from outside the corporate firewall, Citrix Virtual Apps and Desktops can use Citrix Gateway (formerly Access Gateway and NetScaler Gateway) technology to secure these connections with TLS. The Citrix Gateway or VPX virtual appliance is an SSL VPN appliance that is deployed in the demilitarized zone (DMZ). It provides a single secure point of access through the corporate firewall.
In deployments where virtual desktops are delivered to users at remote locations such as branch offices, Citrix SD-WAN technology can be employed to optimize performance. Repeaters accelerate performance across WANs. With repeaters in the network, users in the branch office experience LAN-like performance over the WAN. Citrix SD-WAN can prioritize different parts of the user experience so that, for example, the user experience does not degrade in the branch location when a large file or print job is sent over the network. HDX WAN optimization provides tokenized compression and data deduplication, dramatically reducing bandwidth requirements and improving performance.
A site is made up of machines with dedicated roles that allow for scalability, high availability, and failover, and provide a solution that is secure by design. A site consists of VDA-installed servers and desktop machines, and the Delivery Controller, which manages access.
The VDA enables users to connect to desktops and applications. It is installed on virtual machines in the data center for most delivery methods, but it can also be installed on physical PCs for Remote PC Access.
The Controller is made up of independent Windows services that manage resources, applications, and desktops, and optimize and balance user connections. Each site has one or more Controllers. Because sessions are affected by latency, bandwidth, and network reliability, place all Controllers on the same LAN, if possible.
Users never directly access the Controller. The VDA serves as an intermediary between users and the Controller. When users log on using StoreFront, their credentials pass through to the Broker Service on the Controller. The Broker Service then obtains profiles and available resources based on the policies set for them.
After the credentials are verified, information about available applications or desktops is sent back to the user through the StoreFront-Citrix Workspace app pathway. When the user selects applications or desktops from this list, that information goes back down the pathway to the Controller. The Controller then determines the proper VDA to host the specific applications or desktop.
The connection between Citrix Workspace app and the VDA uses the Citrix Gateway Protocol (CGP). If a connection is lost, the Session Reliability feature enables the user to reconnect to the VDA rather than having to relaunch through the management infrastructure. Session Reliability can be enabled or disabled in Citrix policies.
After the client connects to the VDA, the VDA notifies the Controller that the user is logged on. The Controller then sends this information to the site database and starts logging data in the monitoring database.
Every Citrix Virtual Apps and Desktops session produces data that IT can access through Studio or Director. Using Studio, administrators can access real-time data from the Broker Agent to manage sites. Director accesses the same data plus historical data stored in the monitoring database. It also accesses HDX data from NetScaler Gateway for help desk support and troubleshooting.
Within the Controller, the Broker Service reports session data for every session on the machine providing real-time data. The Monitor Service also tracks the real-time data and stores it as historical data in the monitoring database.
You set up the machines that deliver applications and desktops with machine catalogs. Then, you create delivery groups that specify the applications and desktops that will be available (using machines in the catalogs), and which users can access them. Optionally, you can then create application groups to manage collections of applications.
Machine catalogs are collections of virtual or physical machines that you manage as a single entity. These machines, and the application or virtual desktops on them, are the resources you provide to your users. All the machines in a catalog have the same operating system and the same VDA installed. They also have the same applications or virtual desktops.
Typically, you create a master image and use it to create identical VMs in the catalog. For VMs you can specify the provisioning method for the machines in that catalog: Citrix tools (Citrix Provisioning or MCS) or other tools. Alternatively, you can use your own existing images. In that case, you must manage target devices on an individual basis or collectively using third-party electronic software distribution (ESD) tools.
Delivery groups specify which users can access which applications, desktops, or both on which machines. Delivery groups contain machines from your machine catalogs, and Active Directory users who have access to your site. You might assign users to your delivery groups by their Active Directory group, because Active Directory groups and delivery groups are ways to group users with similar requirements.
Each delivery group can contain machines from more than one catalog, and each catalog can contribute machines to more than one delivery group. However, each individual machine can only belong to one delivery group at a time.
You define which resources users in the delivery group can access. For example, to deliver different applications to different users, you might install all the applications on the master image for one catalog and create enough machines in that catalog to distribute among several delivery groups. You can then configure each delivery group to deliver a different subset of applications that are installed on the machines.
