The Definitive Guide to Monitoring Virtual Environments
The virtualization of physical computers has become the backbone of public and private cloud computing from desktops to data centers, enabling organizations to optimize hardware utilization, enhance security, support multi-tenancy and more. These environments are complex and ephemeral, creating requirements and challenges beyond the capability of traditional monitoring tools that were originally designed for static physical environments.

OVERVIEW

The virtualization of physical computers has become the backbone of public and private cloud computing from desktops to data centers, enabling organizations to optimize hardware utilization, enhance security, support multi-tenancy and more. These environments are complex and ephemeral, creating requirements and challenges beyond the capability of traditional monitoring tools that were originally designed for static physical environments. But modern solutions exist, and can bring your virtual environment to new levels of efficiency, performance and scale.

This guide explains the pervasiveness of virtualized environments in modern data centers, the demand these environments create for more robust monitoring and analytics solutions, and the keys to getting the most out of virtualization deployments.

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.

The Next Generation VDI Reference Architecture on Cloudistics Ignite
Desktop and application virtualization is one of the primary ways how businesses reduce CapEx and OpEx, improve time to market, efficiency, increase control, and expand connectivity. VDI enables users to now access their desktops hosted in a data center server as virtual machines, which can be accessed from laptops and thin clients. Although desktop virtualization has existed for many years, many implementers of the technology have discovered that significant hurdles need to be overcome to fully

Desktop and application virtualization is one of the primary ways how businesses reduce CapEx and OpEx, improve time to market, efficiency, increase control, and expand connectivity. VDI enables users to now access their desktops hosted in a data center server as virtual machines, which can be accessed from laptops and thin clients. Although desktop virtualization has existed for many years, many implementers of the technology have discovered that significant hurdles need to be overcome to fully reap its benefits.

This document defines a set of architectural blocks for building a multitenant, Virtual Desktop Infrastructure in and application services on the Cloudistics platform.
This document includes 2 major sections:

  • VDI Solution Architecture
  • Overview of Cloudistics Ignite Platform Components (Appendix A)
The primary goal of this VDI architecture is to enable service providers and IT departments to create secure, scalable, and reliable desktop hosting solution offers for small- and medium-sized organizations ranging from 500 to 1,000 users. The intended audience is hosting providers, and IT departments who want to leverage the Cloudistics infrastructure services to deliver desktop hosting services to multiple tenants.

To deliver a desktop hosting solution, service provider partners can leverage Windows Server and the Windows Desktop Experience feature to deliver Windows users a highly performant application experience that is familiar to business users and consumers.

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.
