PoC Guide: Getting Started with Citrix Desktops-as-a-Service (DaaS)

Overview

The Citrix Desktops-as-a-Service (DaaS) allows you to provide employees with a full workspace from any device while leaving most of the setup, upgrades, and monitoring to Citrix. IT will continue to manage and control the virtual machines, applications, and policies on the back end, while Citrix manages all the key infrastructure, installation, setup, and upgrades needed to maintain a Citrix environment. This reduces administrative overload and ensures you have all the latest features and functionality.

Conceptual Architecture

Components

Hosted by Citrix:

• Workspace: complete digital workspace that lets you securely deliver virtual apps, web and SaaS apps, and desktops, to your end-users.
• Gateway Service: allows secure, contextual remote access to apps and data
• DaaS: allows IT to provide virtual apps and desktops to their end users

Hosted by Customer:

• Cloud Connector: serves as a channel for communication between Citrix Cloud and your resource location. Although this is hosted within the customer's resource location, it is managed by Citrix and kept evergreen. A minimum of two Cloud Connectors per resource location is recommended so that there is no loss in communication with Citrix Cloud.
• Virtual Delivery Agent: The VDA is used to register with the Cloud connector so connections can be brokered between the end-user's device and the virtual machine

Scope

This proof-of-concept guide describes the following:

1. Creating a Citrix Cloud account
2. Requesting a Citrix DaaS trial
3. Creating a Resource Location and installing the Citrix Cloud Connectors
4. Installing Citrix Virtual Delivery Agent on the virtual machines
5. Creating a Machine Catalog in Citrix DaaS
6. Creating a Delivery Group
7. Launching a session from Citrix Workspace

Prerequisites

VM Requirements

Prior to starting this POC, you need to create an image and install any application you would like to deliver to your end users.

Virtual Delivery Agents (VDAs) are required on each physical or virtual machine that delivers applications and desktops and register with the cloud connectors. VDAs can be installed in either single-session or multi-session OS. The following operating systems are supported:

• Windows 10 (see CTX224843 for edition support) multi-session and single session
• Windows 7
• Windows Server 2012 R2 and newer

Cloud Connector Requirements

The cloud connectors act as the communication channel between the components hosted in Citrix Cloud and the components hosted in the resource location. The cloud connectors act as a proxy for the delivery controller in Citrix Cloud. To install the Citrix Cloud Connectors in your environment, you require (at least two) Windows Server 2012 R2 or later server machines/VMs. You require static IPs for these two machines. Windows installation and domain join of these machines must have been done in advance. The system requirements for the Cloud Connectors are here. Review the guidance on the cloud connector installation here. The machine the Citrix Cloud Connector runs on must have network access to all the virtual machines that are to be made available on the internet via the Citrix Workspace.

Some requirements for the Citrix Cloud Connector installation (installer performs checks for these) are:

The Citrix Cloud Connector machine must have outbound Internet access on port 443, and port 80 to only *.digicert.com. The port 80 requirement is for X.509 certificate validation. See more info here

Microsoft .NET Framework 4.7.2 or later must be pre-installed on the machine

Time on the machine must be synced with UTC

The Cloud Connector Connectivity Check Utility tool can be used to test the reachability of the Citrix Cloud and its related services

Deployment Steps

Create Citrix Cloud Account

If you are an existing Citrix Cloud customer, skip to the next section: Request Citrix DaaS Trial. Ensure that you have an active Citrix Cloud account. If your account has expired, contact your account manager to enable it.

If you need to sign up for a new Citrix Cloud account please follow the step by step instructions here: Signing up for Citrix Cloud

Request a Citrix DaaS Trial

You can evaluate Citrix DaaS by request through Citrix. From a trial, you can convert to a paid service subscription. To request a trial, follow these instructions.

Note For some services you must request a demo from a Citrix sales representative before you can try out the service. Requesting a demo allows you to discuss your organization’s cloud service needs with a Citrix sales representative. Also, the sales representative ensures you have all the information needed to use the service successfully.

When your trial is approved and ready to use, Citrix sends you an email notification.

Create a Resource Location

Resource locations contain the resources required to deliver applications and desktops to your users. Your resource locations include your active delivery domain controller, your hypervisor or cloud services (hosts), your session hosts, and your cloud connectors.

1. Log in to your Citrix Cloud Console from your cloud connector (this can be done via RDP).
2. Under Resource Locations Click Edit or Add New

3. Click Add a Resource Location

4. Click the ellipses on the top right of the new resource location. Click Manage Resource Location.

   

5. Enter a new name of the New Resource Location. Click Confirm

6. Under the newly created resource location click + Cloud Connectors

7. Click Download. Click Run once the download finishes

8. Citrix Cloud connectivity test successful message is displayed. Click Close. If the test fails, check the following link to resolve the issue. You may also use the Cloud Connector Connectivity Check Utility tool to verify all addresses are reachable

9. Click Sign In and Install

10. Sign in to your Citrix Cloud account using the user name and password combination you have previously setup.

11. From the drop-down menu select the appropriate Customer and Resource Location (Resource location drop-down menu will not be displayed if there is only one resource location). Click Install

12. Once the installation completes, a service connectivity test runs. Let it complete and you see a successful result. Click Close

13. Refresh the Resource Location page in Citrix Cloud.

14. Click Cloud Connectors

15. The newly added Cloud Connector is listed. Repeat to install another Cloud Connector in the Resource Location on the second Windows server machine that you prepared.
