Solution Guide for Sennheiser Headsets, IGEL Endpoints and Skype for Business on Citrix VDI
Topics: IGEL, Citrix, skype, VDI
Enabling voice and video with a bundled solution in an existing Citrix environment delivers clearer and crisper voice and video than legacy phone systems. This solution guide describes how Sennheiser headsets combine with Citrix infrastructure and IGEL endpoints to provide a better, more secure user experience. It also describes how to deploy the bundled Citrix-Sennheiser-IGEL solution.

Virtualizing Windows applications and desktops in the data center or cloud has compelling security, mobility and management benefits, but delivering real-time voice and video in a virtual environment is a challenge. A poorly optimized implementation can increase costs and compromise user experience. Server scalability and bandwidth efficiency may be less than optimal, and audio-video quality may be degraded.

Ovum: Igel's Security Enhancements for Thin Clients
Thin client vendor Igel is enhancing the security capabilities of its products, both under its own steam and in collaboration with technology partners. Ovum sees these developments as important for the next wave of thin client computing, which will be software-based – particularly if the desktop-as-a-service (DaaS) market is to take off.

With hardware-based thin client shipments in the region of 4–5 million units annually, this market is still a drop in the ocean compared to the 270 million PCs shipping each year, though the latter figure has been declining since 2011. And within the thin client market, Igel is in fourth place behind Dell and HP (each at around 1.2 million units annually) and China’s Centerm, which only sells into its home market.

However, the future for thin clients looks bright, in that the software-based segment of the market  (which some analyst houses refuse to acknowledge) is expanding, particularly for Igel. Virtual desktop infrastructure (VDI) technology has stimulated this growth, but the greatest promise is probably in the embryonic DaaS market, whereby enterprises will have standard images for their workforce hosted by service providers.

The Next Generation Clusterless Federation Design in the Cloudistics Cloud Platform
Is there another way to manage your VMs? Yes, the introduction of the Cloudistics Cloud Platform has an innovative approach – non-clustered (or clusterless) federated design.The clusterless federation of the Cloudistics Cloud platform uses categories and tags to characterize computer nodes, migration zones, and storage groups (or blocks). With these benefits: ⦁ Node Limits Are A Thing of the Past. ⦁ Locking limitations are removed. ⦁ Flexibility is Enhanced. ⦁ Ladders of Latency are Removed. ⦁

This paper is written in the context of modern virtualized infrastructures, such as VMware or Nutanix. In such systems, a hypervisor runs on each compute node creating multiple virtual machines (VMs) per compute node. A guest OS runs inside each VM.

Data associated with each VM is stored in one or more virtual disks (vDisks). A virtual disk appears like a local disk, but can be mapped to physical storage in many ways as we will discuss.

Virtualized infrastructures use clustering to provide for non-disruptive VM migration between compute nodes, for load balancing across the nodes, for sharing storage, and for high availability and failover. Clustering is well known and has been used to build
computer systems for a long time. However, in the context of virtualized infrastructures, clustering has a number of significant limitations. Specifically, as we explain below, clusters limit scalability, decrease resource efficiency, hurt performance, reduce flexibility and impair manageability.

In this paper, we will present an innovative alternative architecture that does not have these limitations of clustering. We call our new approach clusterless federation and it is the approach used in the Cloudistics platform.

The rest of this paper is organized as follows. In Section 2, we describe the limitations of clustering and in Section 3, we drive the point home by using the specific example of VMware; other virtualized systems are similar. In Section 4, we present the clusterless federated approach and show how it avoids the limitations of clustering. We summarize in Section 5.

Application Lifecycle Management with Stratusphere UX
Enterprises today are faced with many challenges, and among those at the top of the list is the struggle surrounding the design, deployment, management and operations that support desktop applications. The demand for applications is increasing at an exponential rate, and organizations are being forced to consider platforms beyond physical, virtual and cloud-based environments.
Enterprises today are faced with many challenges, and among those at the top of the list is the struggle surrounding the design, deployment, management and operations that support desktop applications. The demand for applications is increasing at an exponential rate, and organizations are being forced to consider platforms beyond physical, virtual and cloud-based environments. Users have come to expect applications to ‘just work’ on whatever device they have on hand. Combined with the notion that for many organizations, workspaces can be a mix of various delivery approaches, it is vital. to better understand application use, as well as information such as versioning, resource consumption and application user experience. This whitepaper defines three major lifecycle stages—analysis, user experience baselining and operationalization―each of which is composed of several crucial steps. The paper also provides practical use examples that will help you create and execute an application-lifecycle methodology using Stratusphere UX from Liquidware.

Application & Desktop Delivery for Dummies
In this book, you learn how solutions, such as Parallels Remote Application Server (RAS), replace traditional application deployment with on-demand application delivery, and why it's right for your organization.
Applications are essential to the businesses and organizations of all sizes and in all industries. End-users need to have continuous and reliable access to their applications whether working in the office or remotely, at any time of the day or night, and from any device. With the advent of cloud computing, office desktops with installed applications (that had to be constantly updated) have become a thing of the past — application streaming, virtual desktop infrastructure (VDI), and hosted applications are the future (and the present, for that matter). Application virtualization is an easy way to manage, distribute, and maintain business applications. Virtualized applications run on a server, while end-users view and interact with their applications over a network via a remote display protocol. Remote applications can be completely integrated with the user’s desktop so that they appear and behave like local applications. Today, you can dynamically publish applications to remote users in several ways. The server-based operating system (OS) instances that run remote applications can be shared with other users (a terminal services desktop), or the application can be running on its own OS instance on the server (a VDI desktop).
Switch to Parallels Remote Application Server and Save 60% Compared to Citrix XenApp
This article will explain how Parallels Remote Application Server can easily act as a business’s desktop and application delivery solution, offering the same qualities as other leading solutions such as Citrix XenApp, but at an entirely different and affordable price. As a result, companies who opt to use Parallels Remote Application Server could save up to 60%, while gaining added flexibility and maneuverability for their devices.
A few years ago, Citrix had two separate products for its virtualization solutions: XenApp and XenDesktop. In 2016, Citrix merged them into a single product; XenDesktop 7. The change was not well received by Citrix customers, and Citrix has split them again into XenApp and XenDesktop from version 7.5 onward. The major difference between XenApp and XenDesktop is the type of virtual desktop delivered to the user. XenDesktop includes all XenApp features and also has a VDI solution, so from this point on we will use the XenDesktop term in this document to refer to Citrix virtualization solution: published applications and virtual desktop infrastructure. Although XenDesktop is the most popular solution in the industry, it has several shortcomings coupled with a very expensive price tag. Due to migration from Independent Management Architecture (IMA) to Flexcast Management Architecture (FMA), there is no option in place to upgrade to XenDesktop 7.x from previous versions of XenApp (5 or 6.X). Therefore, now is the right time to jump ship. In this white paper, we examine how migrating to Parallels Remote Application Server can reduce the costs of an application and virtual desktop delivery solution by more than 60%. Parallels RAS is an easy-to-use, scalable application and desktop delivery solution which has the lowest total cost of ownership amongst its competitors. Considered an industry underdog by many, Parallels Remote Application Server has been in the industry since 2005, and many Citrix customers have already switched to Parallels RAS.
How Parallels Remote Application Server Enhances Microsoft RDS
The revolutionary potential of remote desktops is just being tapped. This article will illustrate how remote desktops can help companies work more efficiently and effectively, reducing costs and harmoniously integrating solutions such as thin clients. In addition, by delivering applications and data straight to thin clients, remote desktops simplify digital policies by centralizing data directly onto the company’s server.
In 2001, Microsoft introduced the RDP protocol, a proprietary protocol that allowed users to access an operating system’s desktop remotely. Since then, Microsoft has come a long way, developing Remote Desktop Services to facilitate remote desktop access. Formerly known as Terminal Services, RDS consists of a number of tools and services that allow businesses to build an application and virtual desktop delivery solution that their users can access remotely. However, the Microsoft RDS solution leaves a lot to be desired. This white paper looks at the pain points of Microsoft RDS solutions, and how systems administrators can use Parallels® Remote Application Server to enhance their RDS infrastructure and provide the functionality their businesses need to give their users the flexibility they need to be more productive.
