Deploying Citrix XenApp 7.11 and NetScaler on Microsoft Azure using Azure Resource Manager (ARM) White Paper
Microsoft Azure is a reliable and flexible cloud platform that allows simple as well as multi-tier applications to be deployed quickly in Microsoft-managed datacenters. This paper describes an architecture for deploying Citrix XenApp® 7.11 or Citrix XenDesktop® 7.11 and NetScaler on Azure and discusses design decisions that impact the deployment architecture.
This deployment guide also describes Azure concepts and components, and basic Azure implementation using ARM. ARM deployment differs from the “classic” Service Management (ASM) model available previously with respect to how Azure components are managed and monitored. ARM also provides security, auditing, and tagging features that make it easier to allocate and control Azure resources. All new Azure deployments will use the ARM model.
The architecture presented here delivers Citrix application and desktop services to users. It enables a hybrid approach in which organizations can extend on-premises infrastructure and use Azure IaaS to deliver cloud-based services. Key objectives for the design include easy scalability of XenApp and XenDesktop workloads as well as high availability.
Assuming they have the appropriate enterprise licensing, some organizations may want to deploy pooled Windows 10 virtual desktops (VDI) in addition to XenApp sessions supporting hosted shared desktops (HSDs). Since XenDesktop 7.11 shares the same software architecture and installation methodology as XenApp 7.11, administrators can easily deploy mixed workloads on Azure when VDI desktops are also required. This paper provides scalability and design guidelines that can be used to size mixed HSD and Server VDI workloads on Azure.
To understand design decisions, this paper describes underlying Azure and Citrix components that are required for a deployment and explains differences from an on-premises XenApp deployment (for example, this architecture performs load balancing and traffic management using Azure-provided NetScaler VPX instances).
The first part of this guide describes the solution architecture. The second part is a “runbook” that gives specific procedures to install and configure a sample XenApp deployment on Azure.
