XenApp Essentials Service Deployment Guide

January 2018

XenApp Essentials Service delivers Windows applications from Microsoft Azure to any device securely. The service combines the industry-leading XenApp service with the power and flexibility of Microsoft Azure. This document guides you through configuring the Azure environment by using Azure Resource Manager and the XenApp Essentials Service. Introduction Microsoft Azure is a reliable and flexible cloud platform that allows quick deployment of applications in Microsoft-managed data centers. This paper provides guidelines for deploying the XenApp® Essentials Service on Azure and discusses decisions that impact deployment scenarios. This deployment guide also describes Azure concepts and components, and basic Azure implementation using Azure Resource Manager. Azure Resource Manager deployment differs from the "classic" Service Management (ASM) model available previously in how Azure components are managed and monitored. Azure Resource Manager also provides security, auditing, and tagging features to allocate and control Azure resources. All new Azure deployments use the Azure Resource Manager model. This paper describes underlying Azure and Citrix components that are required for the deployment. The first part of this guide describes the overall solution deployment. The second part is a "runbook" that gives specific procedures to install and configure a sample XenApp Essentials deployment on Azure.

Overview XenApp Essentials Service combines the power of the Citrix Cloud with Microsoft Azure to deliver Windows applications. XenApp Essentials Service replaces Microsoft RemoteApp and provides the same application access experience for users. XenApp Essentials Service provides performance and flexibility by moving application delivery to the cloud, without sacrificing management or user experience.

This guide is for customers who have the technical skills to deploy XenApp Essentials Service in Azure. Figure 1 at a high level describes the Citrix Cloud service offerings. Figure 2 describes a conceptual XenApp Essentials Service deployment in Azure.

Microsoft Azure Infrastructure as a Service makes it possible to create new virtual machines in minutes and adjust usage quickly when infrastructure requirements change. By provisioning XenApp Essentials workloads on Azure, businesses can avoid the acquisition and maintenance costs associated with expanding on-premises infrastructure. Instead, they can use Azure to supply the compute, storage, and networking resources to provision application sessions to meet demand.

Concepts and Terminology Azure hosts infrastructure components in different Microsoft-managed data centers. Azure services can vary according to geographic regions, different Infrastructure as a Service capabilities, and different usage-based pricing. At the time of writing this document, Azure is generally available in 30 regions around the world. Azure Resource Manager deployment model concepts The Azure Resource Management deployment model is based around the concept of flexible, virtualized Infrastructure as a Service resource.

This guide introduces fundamental Azure concepts that describe general compute, storage, and networking requirements. Azure compute To deploy XenApp Essentials on Azure, these compute resources are relevant: Virtual machines. Virtual machines supply basic functionality and assigned compute, memory, and I/O resources based on an Azure compute instance type. Availability Sets. Assigning virtual machines to an

Figure 3 shows a storage account that

Resource Group

Azure Resource Manager enables you to support the resources in your solution as a group. You can deploy, update, or remove all the resources for your solution in a single, coordinated operation. You can use a template for deployment and that template can work for different environments such as testing, staging, and production. In Azure Resource Manager, you can create resources by using the Azure portal interface as described in this guide. You can also use PowerShell commands to create resources. There are three critical types of Azure Resource Manager resources — compute, storage, and networking — that are required to deploy XenApp Essentials workloads on Azure. The Azure Resource Manager model organizes these resources into management containers called Resource Groups. In the Azure Resource Manager model, Resource Groups offer these advantages: Resources can be deployed, managed, and monitored as a group, simplifying deployment steps. Resources can be easily removed by deleting the group only that contains all objects. Resources can be defined with dependencies in a Resource Group, allowing them to be deployed in the correct order. Resources can be defined with RoleBased Access Controls (RBAC), which enables decentralized management. Resources can be tagged to organize them within a subscription.

Azure storage Azure provides different storage categories and redundancy options. Storage pricing is tiered with lower rates for higher levels of use. Charges vary depending on the following:  Storage capacity  Type of data replication  Number of I/O operations per second  Data transfer

is the same as GRS but supplies read access to the secondary data center. For infrastructure components in Azure, Citrix recommends using Geographically Redundant Storage (GRS)—the mid-tier availability option—to enable high availability infrastructure. Configure XenApp Essentials to use Locally Redundant Storage (LRS) because a deployment typically uses multiple identical workload servers providing redundancy. Infrastructure and application storage in Azure The XenApp Essentials workload server and application storage needs about 30 GB of storage. This amount can vary depending on the size of the application workload. To conserve costs, it’s best to install a clean XenApp Essentials workload Master image server to minimize required capacity. User profile storage in Azure User data storage is a critical architectural element and a reasonable size estimate for a user profile is 25 GB per user. XenApp Essentials Service uses the XenApp Profile Management solution to enable profiles and Microsoft folder redirection.

documentation). Site-to-site VPNs are protected using industry-standard IPsec protocol for secure communications. There is no cost to set up a virtual network. Microsoft charges for VPN gateways in Azure that connect to other Azure virtual networks or to an on-premises network. Data transfers to an Azure data center are free but Microsoft charges for outgoing data (for pricing specifics, see Virtual Network Pricing). Azure virtual machines acquire network settings during creation. Citrix recommends designing the virtual networking setup during the early deployment stages. The process of creating virtual machines includes steps to define and configure the virtual network and its address space. Other infrastructure components In support of a XenApp Essentials deployment on Azure, Azure configures or provides the following extra components: Active Directory For user authentication and access management, the deployment requires Active Directory Domain Services. In XenApp Essentials, the approach provides three options to choose from:  

Storage transactions in Azure Microsoft also imposes a charge for the total number of storage transactions, including read and write operations. Microsoft limits the standard storage account to a maximum of 20,000 I/O operations per second. This constraint factors into the deployment, as noted in the topology discussion. Azure networking Azure enables flexible networking and network options to support various deployment scenarios. Azure permits the creation of standalone, cloud-only virtual networks, and virtual private networks (VPNs) that support cross-premises connectivity. Virtual machines constructed within an Azure virtual network can communicate directly and securely with one another. There is no cost associated with virtual machine communication or data transfers within a single region. To provide cross-premises connectivity across Azure regions or to an on-premises data center, it’s also possible to configure VPN gateways (see VPN Gateway

More considerations for XenApp Essentials deployments on Azure Deployments in Azure are subject to certain subscription and service limits, quotas, and constraints (see http://azure.microsoft.com/ en-us/documentation/articles/azuresubscription-service-limits/). When deploying XenApp Essentials Service on Azure, consider the following: The following deployment considerations are important in larger scale deployments: I/O operations per second constraints. A single storage account is limited to a maximum of 20,000 I/O operations per second. For A-Series Standard, D-Series Standard, and Dv2-Series Standard Azure instances, Microsoft recommends a maximum of 40 high availability VHDs per storage account. This amount allows a maximum of 500 I/O operations per second per disk (see Sizes for virtual machines). The deployment presented here adheres to these guidelines.

Use a replica of the on-premises Active Directory in Azure Build a standalone domain with its own Azure Active Director Domain Services (described in this paper).



Use Azure Active Directory Domain Services. For more information, see "Install a replica Active Directory domain controller in an Azure virtual network."



Note: Azure Active Directory is not currently supported.

DNS Azure can provide name resolution, or can use an external DNS server. This deployment requires a customer-defined DNS server. DHCP and IP address configuration Azure provides DHCP services that assign private IP addresses to virtual machines using a specified IP address range. Using the Azure portal, an administrator can configure the IP address range and specify static IP address assignments with a persistent long-term lease.

Citrix deployment concepts XenApp Essentials Service gives IT departments the flexibility of delivering Windows applications at an economical price. When implementing XenApp Essentials on Azure, the deployment architecture follows a simplistic approach for provisioning the workloads. Figure 4 shows that only two virtual servers are required for infrastructure. These virtual machines are the Citrix Cloud Connectors. Cloud Connectors serve as a channel for communication between Citrix Cloud and your resource locations in Azure. You can enable cloud management without requiring any complex networking or infrastructure configuration, such as VPNs or IPsec tunnels. In a XenApp Essentials deployment, the "NetScaler Gateway Service" for secure access requires no configuration. XenApp Essentials Service automates creating the StoreFront site.

The default IP address is set to dynamic. The virtual machine retains the IP address until you remove the virtual machine from the resource group. Some machines, such as domain controllers, require a static IP address. You can change machines to use a static IP address by using the Azure portal, PowerShell, or the Azure CLI.

Scalability testing on different Azure instance types Microsoft Azure instance types vary according to infrastructure resources and relative cost per hour. Pricing for Azure virtual machines varies by region and includes Windows licensing. For more information, see Windows Virtual Machines Pricing. Citrix engineers conducted single-server scalability testing to determine optimal user densities and cost-per-user under different XenApp session workloads and various Azure instance types. The testing,

described in the paper "Deploying Citrix XenApp on Microsoft Azure cloud: the scalability and economics of delivering Citrix XenApp services," simulated user  Microsoft Azure A-Series Standard  D-Series Standard  Dv2-Series Standard Login VSI 4.1.6 was used in testing to generate user connections to XenApp VDA workers, simulating typical user workloads running on Azure instances (Note: Login VSI uses the concept of Task Workers or Knowledge Workers for user simulation purposes). Testing results indicate that the D2v2 virtual machines use faster processors and local SSD storage devices for caching. The D2v2 virtual machines can provide higher performance for workloads servers than the respective A-Series and D-Series virtual machines. In addition, D2v2 instances offer the lowest cost per user for typical XenApp workloads.

The workload instances (server VDA) are the workload virtual machines hosting the applications delivered to your users. Actual deployments can include other services not shown in Figure 4: These include Active Directory, DNS, DHCP, and file services. Basic topology and networking considerations This section describes a simple topology for deploying XenApp Essentials on Azure, as shown in Figure 4. IP address assignment Virtual machines receive a private IP address from a range that is based on the subnet to which they are assigned.

Runbook: Preparation Tasks and Prerequisites. The focus for the remainder of this document is on the detailed process of setting up and deploying the system. There are four major steps in the overall process: 1. Set up an Azure account and configure the Azure Infrastructure as a Service topology (virtual networks, storage accounts, Resource Groups, Availability Sets, and infrastructure virtual machines). This step also includes the configuration of Azure Active Directory. a. In this example deployment, the Citrix Cloud Connectors are configured automatically as part of the XenApp Essentials first catalog setup. 2. Prepare and deploy the XenApp Essentials workload master image. a. Optionally, Citrix-prepared images are available for use. Citrix recommends that you deploy a prepared image in a test environment only. 3. Create a XenApp Essentials catalog. a. Publish applications to users. 4. Access applications.

Plan Your Deployment The first step in an Azure implementation is to create a sizing plan based on specific requirements. The appropriate number of resource groups, storage accounts, and virtual machines depends on estimates for the number and type of users in the environment. There are different server functions that must be considered in the sizing of Azure resources: Infrastructure servers and workload servers. In planning, it is necessary to consider the appropriate sizing of each. Appendix A provides tables that you can prepopulate with customer-specific details before starting the configurations in the runbook section. Citrix recommends that you update these tables to reflect detailed requirements and nomenclature before proceeding.

Step 1: Preparing and Linking your Azure Subscription In this step, you create the Azure topology, which includes virtual networks, storage accounts, resource groups, availability sets, and virtual machines. It’s assumed that the administrator created a Microsoft Azure account, and has some general experience with creating virtual machines in Azure. To configure the topology in Azure for a XenApp Essentials Service deployment, you must first establish these prerequisites: 1. Create a resource group 2. Create an Azure virtual network 3. Create Azure storage accounts 4. Create the Azure subscription account used in XenApp Essentials 5. Create virtual machines for infrastructure servers (Optional)

Create an Azure Resource Group The administrator creates resource groups. In this test deployment, type ctx-resource-group1 as the resource group name. (ctx-resource-group1 is used as the resource group for the XenApp Essentials components). Instructions

Create an Azure Virtual Network XenApp Essentials requires an Azure virtual network. Specify the settings for the virtual network, which include:  Virtual network name  Address space  Subnet name  Subnet address range For the virtual network name, use ctx-vnet1. For the resource group name, use ctx-resource-group1. Use the defaults for the other settings. Note1: For this deployment, place all virtual machines in the same virtual network. Existing infrastructure virtual machines such as Active Directory or File Services must reside in this same virtual network. You can also use virtual network peering between virtual networks. For more information, see Create a virtual network peering using the Azure portal on the Microsoft website. Note2: For production environments, it is important to configure the network according to recommended Azure deployment practices. For more information, see Virtual Network Documentation on the Microsoft website. Instructions

Create an Azure Storage Account This section describes creating a storage account. A storage account is required when importing a master image from your Azure subscription. You can use either an existing storage account or a newly created account. For more information, see Preparing a Master Image and Uploading a Master Image for this storage account. The example here assumes that you are creating a single storage account. You configure the storage account by using Standard-RAGRS (Read-Access Geo-Redundant) as the storage replication type.

Creating the Subscription Account to be used in XenApp Essentials Azure Resource Manager uses Azure Active Directory for authentication. Before you provision a virtual machine, it must successfully authenticate against the Azure Active Directory tenant to which the subscription is linked. For this reason, it’s necessary to set up an Azure Active Directory account (traditional Microsoft accounts are not sufficient). The account used must be able to administer the Azure Active Directory tenant linked to the subscription. The user account requires:  Global administrator role for Azure Active Directory  Owner permissions for the subscription For more information, see "XenApp on Azure: Demystifying Azure AD Authentication". Also, see "How to Add or Change Azure Administrator Roles" and "How to get an Azure Active Directory tenant.") The following procedure shows the process of creating an account in Azure Active Directory. You configure the account in the Azure classic portal. You connect to the classic portal by choosing Active Directory in the Azure portal. Then, click Classic portal at the top of the Active Directory page. Instructions

Creating Azure Virtual Machines When you create virtual machines, XenApp Essentials creates Cloud Connectors automatically. During installation, the Cloud connector setup creates two A2v2 instances. The two A2v2 instances can potentially support up to 1,000 concurrent typical knowledge worker sessions. Extra components that might be required, such as domain controllers and file services are not included in this paper. Note: To optimize the availability of services, Citrix recommends creating pairs of virtual machines for most infrastructure functions. You can then place the virtual machines into availability sets. There are two ways to build infrastructure (Active Directory, and file services) and the XenApp Essentials master image: 1. Manually by using the Azure portal (http://portal.azure.com) 2. Automatically by using a PowerShell script. Load testing determines the instance type used in a deployment. In this example deployment, D2v2 or DS2v2 instances are used to deploy virtual machines. (The D2v2 instance type uses HDDs and the DS2v2 instance type uses SSDs for persistent storage, with similar CPU and memory configurations). If load testing indicates that persistent SSD storage is needed for virtual machines, Citrix recommends DS-series instances (such as DS2v2 instances).

HUB:



HUB reduces the cost of running VMs in Azure to the base compute rate, since it waives the price of additional Windows Server licenses from the Azure gallery. You need to bring your on-premises Windows Servers images to Azure to use HUB. Azure gallery images are not supported. Onpremises Windows Client licenses are currently not supported.

The capacity buffer enables extra sessions to be ready for demand spikes, as a percentage of current session demand. For example, if there are 100 active sessions and the capacity buffer is 10%, Citrix provides capacity for 110 sessions. As the total session capacity changes, the number of running instances for this catalog scales. The number of running instances always stays within the configured minimum and maximum values. A lower capacity buffer percentage can result in a decreased cost, but could also result in some sessions having an extended logon time if several sessions start concurrently.

To deploy the catalog and configuration, click Start Deployment.

It can take 1–2 hours to deploy the catalog. The length of time depends on the number of virtual machines you selected for workloads. When using a proxy If your deployment uses a proxy for external Internet access, catalog creation will fail because the virtual network that you specify (when you link your Azure subscription) doesn't have that access. To resolve this, after the failure: 1. In Azure, create two Windows Server 2012 R2 or Windows Server 2016 VMs on the virtual network, and join them to your domain. 2. From the Citrix Cloud console, install a Citrix Cloud Connector on each server. Be sure to select the resource location that was created for the catalog. 3. From the XenApp Essentials management console, redeploy the catalog.

When catalog creation is complete, you then publish apps and assign users (Item 2).

You can add apps to the catalog manually on the Catalogs tab. Click the ellipsis in the catalog that you want to update. In the context menu, click Manage Apps.

Select Apps and then click + Publish Apps. When prompted, how would you like to publish apps select an option: Publish from Start menu Publish using path In Select App, choose the apps that you want to publish. When you select the application, it publishes automatically.

On the catalog tab, click Users and then click + Add Users.

A dialog box appears asking for you to add either a user or group details. In the example, we use domain users. Note: the actual domain name is obscured.

Configure Profile Management in More Settings In this section, we provide details for configuring Profile Management for your users. Profile Management ensures that personal settings apply to users virtual applications, regardless of the location of the user device. You can enable Profile Management by using the profile optimization service. This service provides a reliable way for managing these settings in Windows. Managing the profiles ensures a consistent experience by maintaining a single profile that follows the user. It consolidates automatically and optimizes user profiles to minimize management and storage requirements. The profile optimization service requires minimal administration, support, and infrastructure. Also, profile optimization provides users with an improved log on and log off experience. The profile optimization service requires a file share where all the personal settings persist. You must specify the share as a UNC path. The path can contain system environment variables, Active Directory user attributes, or Profile Management variables. To learn more about the format of the UNC text string, see To specify the path to the user store. Note the deployment of a File Server for this purpose is not covered in this document. Instructions

Visual

The More Settings tab is on the Catalog tab.

Type the path to the profile share: \\fileserver\share\#sAMAccountName# Click Save.

Note: When enabling Profile Management, consider further optimization of the users profile by configuring folder redirection to minimize the effects of the user profile size. Applying folder redirection complements the Profile Management Solution. For more information, see Microsoft Folder Redirection.

Configure the Microsoft Remote Desktop Services (RDS) License Server The XenApp Essentials Service offering accesses Windows Server remote session capabilities that would typically require a Remote Desktop Services client access license (RDS CAL). The Virtual Delivery Agent (VDA) must be able to contact a Remote Desktop license server to request RDS CALs. You are required to install and activate the license server. For more information, see Activate the Remote Desktop Services License Server. For POC environments, you can use the grace period provided by Microsoft. Using this UI, you can have the XenApp Essentials Service apply the license server settings. You can also configure the license server and per user mode by using the Remote Desktop Services console on the master image. You can also configure the license server by using Microsoft Group Policy settings. For more information, see License your RDS deployment with client access licenses (CALs). Configuring the RDS license server requires the following steps: 1. Install Remote Desktop Services License Server on one of the virtual machines that is always available. The XenApp Essentials workloads must be able to reach this license server. 2. Activate the Remote Desktop Services License Server by using these steps.

3.

Specify the license server address and per user license mode by following the steps as shown next. You can also configure this setting by using Microsoft Group Policy. Note: If you purchased CAL licenses from Microsoft Remote Access, you do not have to install the licenses. You can purchase licenses from Microsoft Remote Access in the Azure Marketplace along with XenApp Essentials. Instructions

The More Settings Tab is located as a sub tab under the Catalog tab

Type the FQDN of the License Server licenseserver.domain.com Click Save.

Step 4: Accessing Applications You can use Citrix Receiver to test application access by using the virtual infrastructure and workloads created. Validate the deployment internally and externally. To validate internally, connect to the Azure virtual machine by using an RDP session. To validate externally, connect with a public URL to the XenApp Essentials StoreFront site.

Appendix B Catalog Creation Summary After creating the catalog, some items are configured within both the Citrix Cloud and Azure environments, called a resource location. The resource location includes:  Cloud Connectors: o Two virtual machines deployed within Azure and configured as Citrix Cloud Connectors:  The default virtual machine type is the A2v2 instance.  The naming of these virtual machines is similar to Xenppxx-Conny. Where xx is derived from an environmental factor and y is an ordinal number.  The virtual machine account goes in an Active Directory container based on selections you made during catalog creation.  The virtual machines go into the resource group based on selections you made during catalog creation.  A new storage account is created in the resource group for each Cloud Connector.  A new availability set is created that hosts the two Cloud Connectors.  XenApp Essentials Service workloads o The number of virtual machines deployed within Azure is based on the number selected during catalog creation.  Creates a resource group for the XenApp Essentials workload virtual machines.  Naming of these virtual machines is similar to Xenppxx-xx-yyy. Where xx is derived from an environmental factor and y is an ordinal number.  Places each virtual machine account into an Active Directory container based on selections you made during catalog creation.  Creates a storage account in the new resource group for all XenApp Essentials virtual machines (up to the limit of the storage account). Within Citrix Cloud, a new resource location is defined with the two Cloud Connectors that were created automatically.
