Citrix, Cisco and EMC Teamwork Cisco Validated design DaaS Deployment Accelerate service provider
Deploying and a business-ready desktop-as-a-service (DaaS) environment scaling can be time consuming and complex, especially across multiple data centers and clouds , Citrix and Cisco understand that the management scale and simplicity to the service provider business model is critical, and together have a new DaaS solution architecture as Cisco Validated Design (CVD), entitled "Desktop-as-a-Service for Service Provider to develop 00- seat virtual desktop infrastructure ". The complete CVD for Citrix Service Provider can be found here. There are service providers an excellent starting point for a comprehensive DaaS solution to implement. This blog summarizes the solution architecture, its components, and conducted to provide tenants and subscribers tests.
to validate the architecture, engineers a test environment comprised of 10 tenants and 00 mixed workload support users, the implementation of performance testing and documentation of the solution.
seenHistorically, service providers have had several tenants to manage sites and data centers independently, performing hosted application and desktop delivery on a per site. Of course there were on the market some alternatives, which made it easier to take a tenant desktop VMs to associate with a specific vLAN, but these solutions still require a large majority of the functionality customers to missing order, the day to day, and relatively complex to manage challenges of end-user expectations and experiences. Let's just say, until recently, not really, it was possible for administrators to see the big picture of all managed tenant environments. Configure services and onboarding subscribers was time-consuming. From a business perspective, the addition of new tenants and subscribers meant that the service providers often had either more staff add to cope with the additional administrative tasks impacted profitability or outsource these tasks to the tenant, which then leads to tenant asking "why I this is different from the base IaaS'm with?"
feature-rich DaaS across multiple tenants, locations, AD domains and isolation models
now , with the introduced capabilities of Citrix App orchestration and Citrix Cloud portal Services Manager, it is possible, feature-rich DaaS to provide capabilities across multiple tenants available sites, Active Directory domains Microsoft and isolation models, provisioning users and services of the administration, the all with a central app orchestration and cloud services portal manager tools and the known features of Citrix NetScaler, XenApp and XenDesktop. The deep integration of Citrix technologies allows administrators to be more productive in order to speed up the process, on-boarding subscribers and efficiently orchestrate and monitor feature rich offer as a supplier the business expands.
Recognizing that the management scale and simplicity is critical to the service provider business model, Citrix and Cisco have a much requested DaaS solution architecture of the leading providers on the service provider market, the Empowerment hardware and infrastructure layer common end-user experience of Citrix provided courtesy of Cisco, all the way through the stack to the managed develop. To validate the architecture, built engineers to support a test environment of 10 tenants and 00 mixed workload users, performance testing to document the implementation and the solution as a Cisco Validated Design (CVD). The complete Cisco Validated Design for Citrix Service Provider gives service providers an excellent starting point for a comprehensive DaaS solution to implement.
The CVD builds a typical-Citrix-based DaaS infrastructure through Active Directory domain configuration distributed. It implements both shared and private delivery site isolation models: eight tenants were shared infrastructure resources provided with (the tenant hosted on the provider's data center) and two private delivery sites configured tenants (tenants are Data Center installations managed by the provider ). A workload mix of 0% XenApp hosted shared desktops (HSD) and 10% XenDesktop VDI server (SVDI) users was provided in the individual tenant environment.
A scalable multi-tenant DaaS architecture
The CVD describes a multi-tenant DaaS architecture that uses this hardware and software technologies:
• Citrix App orchestration 2.5. App orchestration allows service providers to automate and manage the provision of desktop and application rates using an array of insulation models in several tenants. It enables a common management interface across all managed tenants. Zero-Trust Agent (new in app orchestration version 2.5) are installed between Active Directory domains and the app orchestration configuration server to communicate in the private delivery locations.
• CloudPortal Services Manager 11.0.1. CloudPortal Services Manager simplifies the management of tenant on-boarding and user subscriptions. Delegate administrative roles allow tenant administrators for their livelihood and monitor deployment requirements.
• Citrix XenDesktop 7.5. This software release brings together the supply of both Hosted shared desktops (XenApp HSD) and Server (Virtual Desktop Infrastructure XenDesktop SVDI).
• Citrix NetScaler. These virtual appliances provide load balancing and secure access to the service provider domains via SSL (TCP 443) over the public Internet.
• VMware ESXi 5.5. Service providers can deploy XenDesktop in a choice of hypervisors: VMware ESXi (as in this CVD), Microsoft Hyper-V or Citrix XenServer. The infrastructure was 100% virtualized on VMware ESXi 5.5.
• EMC storage system. The blade servers via iSCSI from an EMC booted VNX5400 storage array.
• Cisco Unified Computing System ™ (UCS) B-Series Blade Servers. The Cisco Unified Computing System integrates state-of-the-art x86 servers with storage interfaces and network material in a fully converged data center platform. Wire-once cabling configuration flexibility simple deployment, management and infrastructure changes. The test environment used Cisco UCS B0 M3 blade with two 10-core Intel® Xeon® E5-2680v2 ( "Ivy Bridge") processors and 256 GB 10MHz memory. UCS Director was used to streamline infrastructure deployment.
The CVD constructed a provider environment that can support both shared and private delivery sites, as shown in the figure below. It creates hosted a common discharge point, the desktops and applications on shared tenant. In addition, zero trust mechanisms for delivering hosted desktops and applications are used on private site tenants. App orchestration 2.5 provides a zero Trust Agent, which facilitates communication between the app orchestration configuration server and orchestrated Delivery Controller. familiar Because of this agent, domain not orchestrated between the target domain and the app domain orchestration required. to support
Enterprise-level service, follows the architecture best practices to deliver a high-availability design. The solution has redundant Cisco UCS blade chassis, access switches and fabric interconnects for high performance and high availability. The blades are configured in an N + 1 design that XenDesktop and infrastructure services also supported in the case of a single blade failure. The dual-chassis were fitted with sixteen blades. 2 blades for infrastructure servers and 14 blades 0 hosted virtual desktop users (HVDS) and 1800 hosted shared desktop session user (HSD) to support
The CVD defines an affordable and flexible infrastructure Citrix XenDesktop 7.5 software for the hosting. In addition to improvements to enhance the user experience for hosted Windows applications on mobile devices, XenDesktop 7.5 combines the functionality of previously separate XenApp and XenDesktop published. It provides a unified management framework, installation software and a common policy both HVDS and HSD use. Citrix Provisioning Server 7.1 provides a single wizard that allows administrators to define both types of desktop images and use the provision.
Testing Methodology for Cisco and Citrix-based DaaS
Validation Testing Architecture was performed in the Cisco lab in San Jose, California to DaaS check tenant provisioning , The tests showed the simplicity of the on-boarding process for new tenants and the ability to create a mixed workload of 2,000 HVD and HSD desktops via the 10 different tenants determination. The examination confirmed the extraordinary simplicity of complex multi-tenant on-boarding scenarios and comprehensive Life Cycle Management across multiple locations and Active Directory forests, the combination of Citrix app orchestration, Cloud Portal Services Manager and XenDesktop technologies on Cisco UCS Director managed infrastructure.
