Paper: Citrix Reference Architecture for Multi-Tenant Desktop as a Service

Posted by Kenneth van Surksum   |   Tuesday, August 9th, 2011   |  

Citrix has released a paper titled: Citrix Reference Architecture for Multi-Tenant Desktop as a Service. The paper which contains 56 pages details how to use Citrix XenApp 6 and the Citrix Service Provider Automation Pack to enable the delivery of Microsoft Windows based Desktop as a Service (DaaS) and Software as a Service (SaaS), based on the Microsoft Service Provider License Agreement (SPLA) and Citrix Service Provider (CSP) licensing program to small and medium businesses. (50,000 or fewer active users).


The paper covers the following topics:

  • Conceptual overview
  • Core concepts, covering End-point ubiquity, subscription based licensing, multi-tenancy, single instance management, dynamic assembly, DaaS and SaaS subscription licensing
  • Overview of Reference Architecture Modules, covering IaaS, Multi-tenant DaaS and SaaS, Dashboard and management, End-pints and offices.
  • DaaS Reference Architecture Implementation, covering Multi-tenant design considerations, creation of the IaaS layer, network boundaries and vLANs, Storage and Hypervisor host configuration, Securing the networks, Active Directory and Organizational Unit considerations, Virtual Provisioning and DaaS workloads, applications provisioning, hosted applications, creation of the multi-tenant DaaS and SaaS layer, AD integration, XenApp worker groups and policies, DaaS secure access and accelaration and dashboard and management.


This Citrix Reference Architecture for Multi-Tenant Desktop as a Service represents a common view of those best practices as recommended by Citrix and employed by some of today’s most successful Citrix Service Providers. With core architectural innovations brought to market in XenApp 6, a reliable, scalable, and high-performance solution is now available for those CSPs wanting to provide monthly subscriptions to Windows based SaaS and DaaS services. The CSP XenApp Premium licensing program provides the foundation for aggregating over 1,000 servers across multiple tenants into a single management scope, ultimately providing a solution that enables service providers to build a flexible, scalable, and cost effective architecture to meet their customers’ and business needs.
