Delivering a Better User Experience for Horizon 6 with GPU Technology

VMware Guest Blog by Nick Pandher, Professional Graphics Business Development, AMD

AMD is improving user experiences across a wide variety of platforms including VMware Horizon 6. AMD designs and integrates technology for the new era of computing. AMD technology powers all the leading consumer gaming console solutions ensuring our GPU (Graphics Processing Unit) technology leadership. In the professional graphics market we deliver high performance GPU-based compute solutions using open standards like OpenCL while also delivering industry-leading SPECviewperf 12 performance for workstation graphics solutions. At AMD we want to deliver enterprise-ready GPU technologies not just to standalone workstations and servers but also to users of Horizon 6.

AMD GPU products drive a better user experience for desktop and application delivery. Horizon 6 perfectly blends the needs of the enterprise with a great end-user experience, enhancing that user experience In Horizon 6 with GPU technology is a key area AMD is focusing on.

You may not have heard of AMD GPUs being used in VMware Horizon products. Let’s clarify that right now. AMD has a fully certified vSphere 5.5 solution with vSGA (virtual shared graphics acceleration) graphics delivery. Plus we are investing further to bring even more capabilities to Horizon 6 and current VMware View users.

AMD offers products to address the needs of Horizon 6 users. Our FirePro S Series products provide data center-ready GPUs and when combined with our Sky Technology software we deliver a solution that is ready for vSphere and Horizon. Our workstation AMD FirePro product range will also be enabled to support workstation use cases in Horizon 6 environments.

vSGA: Shared Graphics for Knowledge Worker Users
Using an AMD FirePro S series GPU for servers brings exceptional GPU performance to knowledge worker users when used with our Sky Technology vSGA VIB driver. This brings DirectX capabilities to mainstream VDI knowledge worker users in a cost effective manner using VMware’s vSGA technology with VDI desktops. Knowledge worker users are coming from platforms that had either an integrated or enterprise GPU, it’s therefore essential to have the option to bring better GPU capabilities to users who will need it. You have users who on occasion use imaging and desktop publishing and you also have power users who build presentations or other business collateral where graphics performance helps deliver results. Putting a more cost effective AMD FirePro S series GPU allows those select users to access a GPU that is virtualized by VMware’s vSGA technology across all servers. This allows for technologies like vMotion to be used to ensure better uptime and support for DR scenarios.

With AMD FirePro S series you can afford to deploy our entry level AMD FirePro S7000 on ALL VDI servers ensuring user satisfaction on Horizon deployments.

Beyond vSGA
AMD is working with VMware on new technologies, including vDGA (virtual dedicated graphics acceleration), to deliver workstation-class GPU performance to Horizon platforms. AMD is also developing solutions for multi-user support from a single GPU. Stay tuned! Like the choices you have on storage and networking in your deployments, AMD is here to bring choice to GPUs. This helps your Horizon 6 deployments exceed your users expectations.

For more information please visit AMD FirePro: VDI and Virtualized Workstations. AMD vSGA VIB drivers for AMD FirePro based GPU products running on vSphere with View 5.3 are also now available.

Horizon 6.0 – Cloud Pod Architecture Details

Cloud Pod Architecture and Multi-Data-Center View in Horizon 6

One of the key features of the Horizon Cloud Pod Architecture is the high availability and scale-out of virtual desktops in VMware Horizon 6. Many of you may have heard about this feature referred to as Linked-Mode View or Multi-Data-Center View or Federated View Pods. All of these mean the same thing.

Today, virtual desktops provided by Horizon can be deployed using a block and pod architecture, or design. (Refer to sections titled View Building Blocks and View Pods in the View Architecture Planning Guide.) A single View pod can contain up to five View blocks, can scale up to 10,000 (10K) desktops, and can be deployed in a single data center. Customers looking to scale beyond 10K desktops can deploy multiple View pods. However, each View pod is an independent entity that has its own user entitlements and is managed separately. With the new Horizon 6 Cloud Pod Architecture, customers can aggregate multiple View pods in either the same data center or different data centers and entitle users to a desktop in any location.

Now, let’s look at an example that describes this feature in its entirety. Figure 1 below shows two View pods—Pod 1 and Pod 2. Pod 1 is located in a data center in the United States, and Pod 2 is located in a data center in India. Each pod has two connection brokers—VCS1 and VCS2 in Pod 1, VCS3 and VCS4 in Pod 2. Both Pod 1 and Pod 2 maintain their own user entitlements, which provide a mapping of an end user to a virtual desktop in the respective pod. The new architecture in Horizon 6 introduces two new elements:

  • A global entitlement layer which spans multiple pods (shown as a single layer spanning Pod 1 and Pod 2 in the diagram)
  • An inter-pod communication layer (shown with a bi-directional arrow between Pod 1 and Pod 2 in the diagram)

This new architecture provides three major benefits:

  • Support for active-active deployments – Customers who have multiple data centers can now leverage all the data-center assets efficiently. They can entitle users to desktops either in one or in multiple data centers.
  • Consolidation of multiple pods within a single data center – Multiple pods of desktops within the same data center can be consolidated and managed centrally through a single global user-entitlement layer.
  • Disaster recovery – The global user-entitlement layer can be used to assign a user to desktops in both Pod 1 and Pod 2. If Pod 1 were to become unavailable either due to a data-center failure or to another form of failure, the user could always get to a desktop in Pod 2. It is important to note that this feature assumes that the desktops in Pod 1 and Pod 2 are replicated using some form of data-replication technology.
VMware-Horizon-6-Cloud-Pod-Architecture
Figure 1: Cloud Pod Architecture with Pod 1 in U.S. and Pod 2 in India

Brokering a Desktop in a Cloud Pod Architecture

Figure 1 conceptually illustrates how two View pods can be used to entitle users to desktops in different data centers. Brokering a desktop to a user who logs in from any location follows the simple workflow below:

1. The end user enters the URL or IP address for their View environment, which can be an address of a View Connection Server (broker) or a load balancer, and enters their credentials.

2. The broker looks up both local and global entitlements for the user.

3. The broker gets the current desktop state via inter-pod protocol and returns a list of desktops to the client.

4. The user selects a desktop.

5. If the desktop is remote, the broker launches the remote desktop via inter-pod protocol.

6. The client connects to the remote desktop directly or via a local tunnel.

The top use cases for end-user desktop access are as follows:

  • Global roaming desktop – This is a use case where the end user needs access to a desktop only to access their Windows-based applications. An end user can be located either in India or the U.S. with an entitlement to a nonpersistent desktop pool. The end user gets a desktop in their connected pod (that is, close to their client location—If they connect from India, they get a desktop in India).
  • Global home desktop – This is the typical case where the end user wants to get the same persistent desktop every time they request access, irrespective of their location. To accomplish this, persistent desktop pools in all pods need to be set up. The FromHome policy can be used to direct the user back to their home site. The end user gets the same desktop machine irrespective of which pod they are connected to.
  • Local scale desktop – In this use case, each site has multiple pods, each offering a standard nonpersistent desktop pool. A global entitlement layer provided by Cloud Pod Architecture joins all these pools together. Using the site’s Scope policy, one can control and limit access to a desktop that is available within the site.

Global Entitlement

The global entitlement layer controls the mapping of end users to desktops in a Cloud Pod Architecture. Global entitlement consists of a set of parameters as shown in Figure 2:

VMware-Horizon-6-Cloud-Pod-Architecture-Global-Entitlement
Figure 2: Global Entitlement in the Cloud Pod Architecture

Following are the various parameters of global entitlement:

  • Name – Name of the global entitlement
  • Members – The users and/or groups that share the global entitlement
  • Desktops – Desktops that the members of the global entitlement are entitled to
  • Scope – Controls the scope of search when placing a new desktop session. This allows the administrator to control the amount of cross-data-center traffic.
  • FromHome (true/false) – This controls where the desktop search is started. When false, it starts from the current pod; when true, it starts from the user’s home site.

The scope can be one of:

  • Local – Look only in the local pod for available desktops
  • Site – Look in all pods in the local site (typically in the same data center)
  • All – Look across all pods for an available desktop to service the request

The search order favors local resources, starting in the same pod that the user connected to, then extending to the same site, and then across the entire linked environment. In addition to this default search order, administrators can nominate a home site for a single user or for a group of users. When a global entitlement has the FromHome policy set, the search for a new desktop is started in the user’s home site and not the current connected pod. This ensures that, where needed, the desktop session remains close to any backend resources it needs.

Scale Limits and Maximums

The Cloud Pod Architecture was developed with the goal of scaling View desktop deployments to hundreds of data centers and tens of thousands of desktops. To deliver this capability in time for product launch, the VMware team has done a phenomenal job of validating this feature by focusing the testing efforts on the following scale-out parameters:

  • Number of pods – 4
  • Number of sites – 2
  • Number of desktops – 20,000

This scale is just the beginning, and the team at VMware is committed to increasing these numbers over the next few releases.

Architectural Assumptions

A number of architectural assumptions have been made in delivering this feature:

  • The deployment can have both persistent (stateful) and nonpersistent (stateless) desktops
  • A third-party load balancer such as Geographic DNS or a similar product provides the single-URL capability
  • Replication of desktops or end-user data is provided by a third-party data replication technology
  • WAN links between data centers are sufficiently provisioned and have good latency characteristics—however, the feature works on low-bandwidth, high-latency connections and does not impose either a latency drag or additional bandwidth. It is important to note that user experience varies with both the latency and the bandwidth between data centers.
  • All pods are accessible to each other across the corporate network

As you can see, the Horizon Cloud Pod Architecture further advances end-user mobility by delivering desktops from any data center in any geographic location. This is just the beginning of the journey to the hybrid DaaS era!

VMware Horizon 6 – A Closer Look At Application Remoting

By Warren Ponder, Director of Product Management, End-User Computing, VMware and Pat Lee, Director of End-User Clients, End-User Computing, VMwareToday, I am really excited to share another exciting project I was to be asked to support our team in delivering, with the announcement of Horizon 6. One of the many new capabilities that will be available is application remoting of RDS hosted apps and extended capabilities for RDS based desktops.

There’s been some speculation and many experts have had some really good questions about how, what and why we are doing this so I wanted to provide some color to many of the questions I know people have.

Why Application Remoting now?

Several factors came into play in our decision but the primary factor was customer demand. We spent a lot of time with customers across the globe that included all sizes, levels of expertise, and stages of their journey toward a mobile-cloud vision. We didn’t focus on what we already knew about application remoting, but how customers were actually using app remoting today – what they like, don’t like, and the role they see it playing in the future. We wanted to make sure we understood how their needs around app remoting had evolved so we could introduce the appropriate improvements.

With the increase of mobile devices and cloud services, the mobile-cloud era is upon us. It’s changing the landscape. More than ever customers are looking for simplicity and converged infrastructure. They look to VMware as a strategic partner to deliver SDDC and EUC capabilities supporting their Hybrid Cloud efforts. Working closely with customers it was made clear to us that delivering a single platform that converges virtual desktops, RDS hosted apps, SaaS apps, virtualized ThinApps and even third party solutions such as Citrix XenApp is what customers needed to be successful. This all needs to be possible though a unified workspace that gives their users one place to go for access and consumption.

Building upon what we already have

Some have speculated it would take years for us to build anything serious but that was not the case when adding this capability into VMware Horizon 6 because we had most of what was needed to support App Remoting for some time. Let’s take a look at some of the key components for on-prem or hybrid cloud deployments supporting app remoting:

  • Session Brokering, Load Balancing and Cloud Pods
  • Orchestration
  • Resource bursting, VM migration and Elasticity
  • Image management and provisioning
  • Blast and Blast with PCoIP remoting protocol
  • Broad set of clients for different access devices
  • Monitoring and Management

Integration with RDSH (Remote Desktop Session Host)

Support for RDS or Terminal Server based desktops has always existed in Horizon View. Expanding upon our existing support, we worked closely with Microsoft to build our own protocol provider for RDS. With our own protocol provider we are able to integrate our graphics and protocol stacks such as Blast with PCoIP. This also allows us to eventually enable other remoting capabilities we provide with the Blast user experience on virtual desktops

This is the only proper, supported, way to integrate with Microsoft RDS. Although it’s not an easy undertaking, it provides several benefits. Windows OS and other capabilities unique to RDSH like fair share CPU scheduling, or IP virtualization are all supported. Applications that need session level information, leveraging WTS API’s all work without ISV’s having to do anything special or unfamiliar. Administrators familiar with managing or designing RDSH based desktop or app remoting solutions will feel right at home.

Providing a seamless remoted app experience

A key component of remoting apps is seamless windows. This is the ability to remote one or more applications to the user. Applications should have the behavior and experience of running locally. Two of our personal desktop products, Fusion and Workstation have provided a similar feature for years called Unity. Unity seamlessly integrates applications running in a local VM with the host operating system. Building upon this, we extended it to remotely display applications across networks.

Today, we bring all of our experience making Windows apps run well on multiple platforms with Horizon 6 and deliver an amazing Windows remote application experience for Windows, Mac, iOS and Android users.

From Windows XP SP3 to Windows 8.1 Update 1, the Windows client delivers a great remote application experience for Windows users. With individual applications that have seamless windows in the task bar, jumplist integration and favorites, and the ability to save desktop shortcuts for apps and desktops, the Windows client makes it’s easy to get to your apps and desktops when you want them.

Diagram 1

Mac users get the most seamless way to run remote Windows applications. Use common Mac keyboard shortcuts for cut, copy, and paste. Windows applications show up as individual applications on the dock and you can quit individual Windows applications or open windows using standard Mac keyboard shortcuts. Finally, you can leverage Mission Control to switch to any open Windows application or

window and much more.

Diagram 2

On iOS and Android, swipe to bring up the intuitive sidebar to switch between open application windows, close a specific open window or application, or easily open a new application.

Diagram 3

Integration across Horizon 6

Integration with VMware View is seamless and strait forward. Customers can upgrade existing environments and instantly have the ability to remote RDSH hosted desktops or apps. The only thing needed is the RDSH servers.

View provides ability to create farms, which are groups of RDSH servers hosting apps or desktops. Within View, app pools are created and used to organize application entitlement for users or groups. App Pools can be created automatically using applications discovered across farms. Unique apps that are not registered or started using scripts can also be created manually. Apps can mixed with hosts serving RDSH desktops. Apps can come from multiple farms and a user can also access multiple apps simultaneously.

Users will be able to access their RDS hosted apps or desktops using devices from our broad ecosystem of device partners and the Horizon Client for Windows, Mac, iOS or Android. A client for Linux will also be available soon.

A unified workspace is possible though Horizon Workspace integration. Users can access their SaaS, ThinApps, RDS hosted apps, even apps from Citrix XenApp from one, unified workspace that provides a consistent experience across any device.

Enhanced Management

Need some management? The vCenter Operations team has expanded vCenter operations to include support for RDSH hosts, including integration with PCoIP stats monitoring on a per session basis from RDSH.

Diagram 4

In support of our hybrid cloud delivery, all components of Horizon 6 have been built with a focus on flexibility to ensure that customers can choose on-premise or off-premise or both to deliver a common and consistent experience to their end users from a single Horizon client.

As you can see, a lot of work went into adding this capability to Horizon 6 but we truly believe customers will find that our unified approach and support for all types of applications and desktops can save them time, money and spare them a lot of headaches.

AWS Launches Cloud VDI Service

AWS Launches Cloud VDI Service

Amazon officially enters the desktop virtualisation market with the release of its new WorkSpaces

Amazon Web Services has finally caught up with its rivals in regards to virtual desktop implementations (VDI).

It’s a strange fact that AWS, so far ahead of the curve in hosted cloud services that most other competitors can’t even see its dust, was so equally far behind a slew of other companies — such as Dell Wyse, VMware, Moka Five,nComputing, and Hewlett-Packard — in a sector that is some 15 years old.

AWS WorkSpaces

In truth, the VDI business has always had some type of nagging problem shadowing it over the years: expense, management complexity, latency, and implementation difficulties being foremost among them. Only in the last few years have most of these issues been solved.

With this as background, AWS on 26 March announced the general availability of Amazon WorkSpaces, a fully managed desktop computing service in the cloud that was originally introduced in limited preview at AWS re:Invent in Las Vegas last November.

At the same time, Amazon made it a point to talk trash about private clouds – which, according to a number of industry studies, are now the most popular type of cloud being built.

“All the things you have to spend a lot of money for in a private cloud – security, full automation, monitoring, many other things – we already have at AWS,” Andy Jassy, Amazon Web Services Vice President for Cloud Services, told about 4,000 attendees at an AWS Summit in San Francisco.

Jassy also cited a recent Forrester Research paper that concluded that “92 percent of private clouds are still falling short of the core requirements of self-service, full automation, tracking and monitoring.”

“If you’re not planning on using the public cloud in some significant fashion, you will be at a significant competitive disadvantage,” Jassy said. “Private clouds offer none of the benefits of a robust public cloud and are simply a stopgap solution.”

One enticement for WorkSpaces will that it will cost about half that of current VDI systems, Jassy said. Go here for more details.

Seamless Movement

AWS said the service will work on a number of devices and will allow users to seamlessly move their sessions between desktops, tablets and smartphones. Amazon provided a pricing guide showing a range of $35 (£21) to $75 (£45) per workspace used per month. There is no upfront fee and Workspaces can be added or deleted on a monthly basis.

The desktop virtualisation offering marks a departure for AWS in that the company’s traditional offerings focused on replacing traditional data centre operations, but WorkSpaces offers a direct inroad to customer-device management.

“We believe that eventually very few enterprises will run their own data centres,” Jassy said. “That guides our approach in how we build. We will meet enterprises where they are now, but we will make it simple to transition to where the future workloads will be, in the cloud.”

VDI technology, which stumbled for a few years until some of its inherent problems were solved, is a hot sector again. Earlier this month, VMware launched its Horizon DaaS (desktop as a service), a new cloud-based service that it claims delivers cost-effective, enterprise-class virtual desktops running on VMware vCloud Hybrid Service.

Pivot3 Announces Graphics Acceleration Options for VDI Environments

Pivot3, a leading supplier of video surveillance and virtual desktop (VDI) converged storage appliances, announced a set of graphics acceleration offerings for its vSTAC R2S desktop virtualization (VDI) solutions suite. The three-tier offerings, designed for the complexities of virtualized environments, deliver a richer graphics experience for desktops running on vSTAC R2S and vSTAC R2S P Cubed appliances.

These partner-certified and tested graphics acceleration offerings deliver a streamlined user experience by maximizing graphics operations and display times. By incorporating powerful performance and graphics processing offload cards, users with advanced multimedia, workstation, or graphics-intensive application needs are assured maximum desktop density.

“Desktop administrators need to provide a PC-equivalent or better desktop experience to users, especially Power Users, to gain the most benefit from VDI environments,” said Olivier Thierry, CMO, Pivot3. “With additional offload graphics computing power and performance, Pivot3 vSTAC R2S appliances can now support users in need of graphics intensive application support. In addition, the ability for us to offer this feature set on the same appliance allows customers maximum flexibility and affordability, allowing users to add what they need to their existing configurations without moving to a different family of products.”

NVIDIA GRID technology delivers the ability to offload graphics processing from the central processing unit (CPU) to the graphics processing unit (GPU) in virtualized environments, allowing the data center manager to deliver graphics-rich experiences to users.

“NVIDIA GRID enables graphics-rich applications to have workstation-class performance and reliability from any location on almost any device,” said Justin Boitano, GM NVIDIA GRID Business. “When combined with our GRID solution, the VDI infrastructure delivered by Pivot3 allows organizations to take their VDI deployments to an entirely new level, and deliver rich media and graphic applications with exceptional performance.”

The Teradici® PCoIP® Hardware Accelerator (APEX 2800) reduces CPU overhead by offloading the most active 100 virtual displays to ensure its capabilities are used where most needed. In the process, the server consolidation ratio increases up to 2x.

“One of our primary goals is to deliver the same rich graphics experience in virtualized environments that today’s users are accustomed to with physical workstations,” said Olivier Favre, Director of Product Management, Teradici. “When paired with a GPU in VMware® Horizon View™ environments, the Teradici PCoIP Hardware Accelerator offloads screen compression cycles from the CPU to ensure uncompromised visual computing performance, dynamically across all users. We’re excited to extend our partnership with Pivot3, to improve scalability and drive more benefits to customers around the globe.”

Microsoft Releases VDI ‘Starter Kit’ as Preview – Redmond Channel Partner

Microsoft Releases VDI ‘Starter Kit’ as Preview

Microsoft on Wednesday released a preview version of a new tool, dubbed Virtual Desktop Infrastructure Starter Kit 1.0,
which lets organizations test VDI scenarios using Remote Desktop Services (RDS) protocol.

The kit is only for testing purposes, and should not be used for production environments. The kit "complements" the
management console and wizards used with the RDS server role of Windows Server 2012 R2, according to Microsoft’s
announcement. It comes with a couple of applications, Calculator and WordPad, for testing virtual desktop access scenarios.

The final Starter Kit product is scheduled for release in the second quarter of this year. In the meantime, the preview can be
downloaded at this page.

The kit consists of PowerShell scripts that automate VDI deployments using Microsoft’s RDS protocol (formerly known as
"Terminal Services"). It deploys the Windows Server 2012 R2 RDS server-role components needed, including the connection broker,
session host, virtualization host and Web access components. It can be used with various virtual desktop "collections," including
personal, pooled or session-based ones.

Microsoft defines "a collection" as a group of servers that are managed together as part of a virtual machine (VM) deployment,
according to this TechNet Magazine article. The session-based collections are used for "desktop sessions and RemoteApps housed
on RD Session Host servers." The pooled and personal collections are used for "VM-based desktop sessions and RemoteApps
housed on VMs running Windows 7 or Windows 8."

Microsoft’s RemoteApps technology is a bit different in that the applications are accessed from a window on the end user’s local
machine, according to this TechNet library overview description.

The kit includes configuration settings for VDI deployments, which are contained in an XML file. Testers can modify the file to suit
their needs. For instance, it’s possible to alter the settings to expand from the default number of collections that are preconfigured
with the kit.

The lab environment needed to use the kit requires Windows Server 2012 R2 plus Windows 8.1 or Windows 7 clients, along with two
physical servers. There are some required initial setup steps, too, according Microsoft’s "Part 2" description of the kit. The kit comes
with a "readme" file that provides details about the architecture needed, as well as a deployment guide.

SBC and VDI terms Demystified

Basically there are two techniques to execute desktops in a datacenter and present it to end-users:

Server Based Computing (SBC). Also known as ‘presentation virtualization’ and ‘session virtualization’. Invented by Citrix when it launched WinFrame in 1995. It basically is able to host multiple user sessions on a single operating system. Each user session is able to run it’s own user environment and applications. WinFrame evolved to the current Citrix XenApp. Microsoft acquired the code of Citrix and started it’s own product named Terminal Services. Currently this is called Remote Desktop Services. Both Citrix and Microsoft solutions allow to present individual applications or full desktops.

Virtual Desktop Infrastructure (VDI). VMware is inventor of the VDI-technology. It introduced Virtual Desktop Manager 2.0 at January 24 2008. This was the first VDI solution on the market which involved to the current VMware Horizon View. Citrix released competitor XenDesktop in 2009.
Using VDI each user session runs on a seperate operating system running as a vitual machine hosted by a hypervisor.
VDI is in most scenarios used to present a full desktop to the enduser. Citrix offers in XenDesktop a way to present a single application in a VDI session.(VM hosted apps)

For VDI  many other terms used. One of the reasons is that VMware has legal rights on the name VDI. To prevent copyright issues some vendors decide to use a slightly different naming. Another reason is because different implementations are used in VDI like server and client operating systems.

  • Hosted Virtual Desktops (HVD). Same as VDI but Gartner uses this to prevent copyright issues
  • Centralized Virtual desktops (CVDs)= Same as VDI. Used by IDC
  • Server-hosted virtual desktops (SVHD)= Same as VDI. Mainly used by analyst firms.
  • Hosted VDI Desktops (1-to-1 Windows 7/8)= VDI. Term used by Citrix.
  • hosted private desktop = VDI. Term used by Citrix
  • Server VDI = VDI . A term used by Citrix. It is VDI delivered by Citrix XenDesktop
  • Personal VM-based VDI= VDI where each user has its own, persistent environment stored on unique virtual disks. Applications  which are installed by the user remain available even when session has ended.
  • Pooled VM-based VDI= VDI in which the user environment is reset after the session has ended.
  • Server VDI Workers (VM/Server Isolation) = VDI. A term used by Citrix. In this configuration virtual machines are running Windows Server as a guest operating system without Remote Desktop Services enabled. Each instance is used by a single end user. In most cases a Windows 7/8 look and feel is applied. Citrix XenDesktop is used to run these Windows Server vm’s. The reason to use Windows Server as a operating system for end users is Microsoft not allowing to use Windows client operating systems in multi-tenant infrastructures with shared hardware.

Server based computing terms

  • Session-Based VDI = SBC. Term used  for Remote Desktop Services of Microsoft
  • Session virtualization= SBC.
  • Presentation Virtualization= SBC
  • Terminal Services= The old name for what now is called Microsoft Remote Desktop Services.
  • Hosted-Shared Desktop (multi-user RDS) = SBC. Term used by Citrix which is in fact just Citrix XenApp running on top of Remote Desktop Services
  • MetaFrame, WinFrame, Presentation Server = SBC. Old names for what is now called Citrix XenApp

some other terms for presenting desktops used are:

cloud-hosted desktops = Also known as Desktop as a Service (DaaS). A  set of applications or a full desktop are consumed by end users. The infrastruture to offer these is managed by a service provicer.

VM hosted apps/ VM hosted applications = Uses Citrix XenDesktop to present a single application to the end user instead of a full desktop. Acts as an alternative for published applications available in XenApp.

UP2V

I was getting a bit confused by all the different terms used by vendors like Citrix for ways to present datacenter executed desktops to end-users. This post is an attempt to make clear what vendors and analyst firms like Gartner mean.

Basically there are two techniques to execute desktops in a datacenter and present it to end-users:

Server Based Computing (SBC). Also known as ‘presentation virtualization’ and ‘session virtualization’. Invented by Citrix when it launched WinFrame in 1995.

Don’t Take Your Eyes off VDI – Cisco are Certainly Not!

 
Tony Paikeday of Cisco writes interesting article

This blog post promises to avoid telling you about all the fantabulous (I know that’s not a word) growth expected in the number of hosted virtual desktops to bedeployed by 2016.
  What I do want to share, is how Cisco is ramping up our investments in accelerating your path to virtual desktop success, and how we’re tapping into the fundamentals of our Unified Computing System (UCS) to deliver new VDI efficiencies; the same efficiencies that have made Cisco the 2nd most preferred x86  blade server vendor* worldwide, in just 4 years!  So why are so many organizations moving away from their legacy compute solution, and choosing UCS for VDI workloads and more?

Differentiated capabilities that address VDI pain points: TCO and Manageability

It’s no secret to anyone that VDI is not simple to deploy.  You essentially have to bring together multiple seemingly disparate solution elements (server, storage, virtualization, broker, network, security, etc.) and make them work in a cohesive manner, and then be certain that your implementation will scale from a small pilot of 50 users to hundreds, thousands, or more!  Clearly with such complexity, the last thing you need is a complex compute infrastructure underneath it all.  There are 3 key things at the heart of this, that speak to why UCS is better for VDI:

1.)    Server-resident flash.  Our “On-Board” Architecture for VDI intercepts the rapidly proliferating use of flash based storage solutions that offer expansive IOPS capacity and huge performance.  UCS takes it a step further by offering an integrated solution leveraging our partner Fusion-io.  We’ve additionally delivered reference architectures that extend the use cases and attractiveness of flash-based solutions with appliance approaches (that direct-connect the storage array to our fabric interconnect) as well as more traditional multi-tiered architectures.  More on that in a moment…

2.)    We’ve made it easier to provision and manage the hosts for your virtual desktop deployments.  UCS Service Profile Templates enable rapid deployment from bare metal, creating a zero-touch, mistake-proof, stateless operations model.  Now, when you add the On-Board, server-resident flash to the configuration, you extend the reach of this management model to include high-performance, economical storage, completely provisioned and managed as part of the blade configuration/profile!  No SAN or associated expertise required!  Perfect for floating, non-persistent desktops.

3.)    Granular visibility across the virtualized infrastructure.  With user desktops now running amidst other mission-critical workloads in the data center, there’s more reason than ever to ensure that you can impart QoS, security and manageability across the multitude of virtual machine traffic flows traversing the data center.  Cisco Virtual Machine Fabric Extender (VM-FEX) and Cisco Nexus 1000v provide the visibility and controls that make this possible, extending physical world policy and administration to virtual.

A Comprehensive Approach to Architectures and Ecosystem

In my recent post “Wristwatches, Bicycle Helmets, and VDI” I talked a little about how the days of One-Size-Fits-All are long gone, and how organizations like yours, need, demand… solution approaches for VDI that are tailor made to your specific IT environment’s scale, embedded resources, budget, etc.  As Cisco moves from a number 2 global position to the market share leader, it’s clear we’ll need to speak to customers of all sizes.  And that means having the solution set and ecosystem to match

1.)    We’ve introduced an expanded suite of solution architectures for VDI, that introduce not only the On-Board approach I mentioned earlier, but also the “Simplified” architecture (UCS Fabric direct-connected to storage appliance) and the “Scalable” architecture (traditional multi-tiered, with Cisco Nexus 5000 as intermediating switch fabric between storage and server).  Additionally we have our Converged Infrastructure models leveraging VCE vBlock and FlexPod that offer convenient, modularized packaging of the complete infrastructure needed to rapidly deploy VDI.

2.)    The architecture suite mentioned above would not be possible without a comprehensive portfolio of technology partners, especially where storage is concerned.  Cisco enjoys a strategic relationship with industry leaders CitrixVMwareNetApp and EMC, and together we’ve made VDI one of the top workloads deployed on UCS with over 1,200 VDI customers in place thus far.  As we expand our market reach, we’ve converged on a select group of technology partners who help us expand our value proposition, offering new exciting capabilities that intercept the flash-based trend, and with whom our customers have sought validated design guidance based on Cisco.  This group currently includes: Atlantis ComputingFusion-io,NexentaNimble StorageTegile, and more on the way!

Clearly there’s a lot going on here with Cisco UCS and VDI…  and with our commitment to anticipate and intersect meaningful technology trends, and the leading solution capabilities of our strategic partner ecosystem, we’re refusing to take our eyes off the VDI-ball, regardless of whether this is the Year of VDI, next year, or the year after that.

Lastly – are you going to Cisco Live at the end of the month?  If so, we’ll have some great news on desktop virtualization content to be had at the event, and how you can connect with helpful demos, sessions and expertise.  Stay tuned!
