Application Response Time for Virtual Operations
For applications running in virtualized, distributed and shared environments it will no longer work to infer the performance of an application by looking at various resource utilization statistics. Rather it is essential to define application performance by measuring response and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

Massive changes are occurring to how applications are built and how they are deployed and run. The benefits of these changes are dramatically increased responsiveness to the business (business agility), increased operational flexibility, and reduced operating costs.

The environments onto which these applications are deployed are also undergoing a fundamental change. Virtualized environments offer increased operational agility which translates into a more responsive IT Operations organization. Cloud Computing offers applications owners a complete out-sourced alternative to internal data center execution environments. IT organizations are in turn responding to public cloud with IT as a Service (IaaS) initiatives.

For applications running in virtualized, distributed and shared environments, it will no longer work to infer the “performance” of an application by looking at various resource utilization statistics. Rather it will become essential to define application performance as response time – and to directly measure the response time and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

How to avoid VM sprawl and improve resource utilization in VMware and Veeam backup infrastructures
You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

Getting virtual sprawl under control will help you reallocate and better provision your existing storage, CPU and memory resources between critical production workloads and high-performance, virtualized applications. With proper resource management, you can save money on extra hardware.

This white paper examines how you can avoid potential VM sprawl risks and automate proactive monitoring by using Veeam ONE, a part of Veeam Availability Suite. Veeam ONE will arm you with a list of VM sprawl indicators and explain how you can pick up and configure a handy report kit to detect and eliminate VM sprawl threats in your VMware environment.

FlexApp Application Layering in ProfileUnity enables applications to be virtualized in such an innate way that they look native to the Windows OS and other applications.

Application Layering leads to much higher rates of compatibility than previous technologies which used Application Isolation to virtualize applications. Once applications have been packaged for layering, they are containerized on virtual hard disks (VHDs) or VMDKs.  They can be centrally assigned to users on a machine-level or “context-aware” basis.

This whitepaper provides an overview of FlexApp concepts and ways in which FlexApp can serve as a cornerstone in an application delivery strategy.

Optimizing the way applications are delivered and managed has been an ongoing challenge in enterprise IT, and the variety of approaches over the years have been received with varying degrees of success. While every method has pros and cons, some of the most stubborn issues include time-to-deliver, application conflicts, plug-ins and licensing. The too-frequent result is high IT overhead, too many gold images and excess spending on application licenses.

Too many companies are settling on less than optimal solutions because that is all they are presented with and they are unaware of the true state of the art for application management. It is possible to dramatically reduce the number of Windows gold images, in some cases to a single image. It is possible to deliver exactly what each and every end user needs to do their job, and nothing else. It is possible for a user to log into a random system and instantly be presented with their personal desktop, all the right applications, plugins and add-ons, the right printers, and the right fonts. It is possible and it is simple.

Citrix AppDisk, when integrated with FSLogix Apps, provides a unique set of features that can improve end-user productivity, reduce IT overhead and lower the cost of desktop management. With FSLogix patent pending Image Masking technology, AppDisk gains very granular and powerful user-based policy control over every aspect of a user’s desktop and applications, and enhances the ability to distribute applications on network attached disk images. FSLogix Apps also enable AppDisks to scale to a much greater degree than any other similar technologies available today.

This document details what is possible when FSLogix is combined with Citrix AppDisk and suggests best practices for installing and configuring the products for maximum flexibility and applicability in various environments.

Disaster Recovery Guide: DR in Virtualized Environments
In this guide you will learn about BC/DR planning with Zerto's Disaster Recovery Solutions for Virtualized Environments.
In today’s always-on, information-driven organizations, business continuity depends completely on IT infrastructures that are up and running 24/7. The costs of downtime are huge and data loss can put a company out of business. Data loss is not only caused by natural disasters, power outages, hardware failure and user errors, but more and more by software problems and cyber security related disasters. Therefore thorough security and business continuity strategies are crucial for modern businesses, minimizing data loss and downtime. Especially now, as data centers become more and more software defined, these private, hybrid and public clouds become more vulnerable to these kinds of threats.

This document outlines key findings on how IGEL helps organizations manage entire fleets of thin clients from a single console. In addition, you will see how IGEL Universal Desktop Converter provides IT organizations with the flexibility they need to convert any compatible thin client, desktop or laptop computer into an IGEL thin client solution, wi

UNC Health Care selects IGEL Universal Desktop Converter (UDC) and IGEL Universal Management Suite (UMS) for simplicity, cost-savings and security.

“The need to provide users with access to their desktops from any device anywhere, anytime is driving a growing number of IT organizations to migrate toward VDI environments,” said Simon Clephan, Vice President of Business Development and Strategic Alliances, IGEL. “One of the key advantages that IGEL brings to the table is the simplicity that comes from being able to manage an entire fleet of thin clients from a single console. Additionally, the IGEL Universal Desktop Converter provides IT organizations with the flexibility they need to convert any compatible thin client, desktop or laptop computer into an IGEL thin client solution, without having to make an upfront investment in new hardware to support their virtualized infrastructures.” 

UNC Health Care selected the IGEL UDC and UMS software for its Citrix VDI deployment following a “bake-off” between thin client solutions. “IGEL won hands down due the simplicity and superiority of its management capabilities,” said James Cole, Technical Architect, UNC Health Care. “And, because the IGEL UDC software is designed to quickly and efficiently convert existing endpoint hardware into IGEL Linux OS-powered thin clients, we knew that by selecting the IGEL solution we would also realize a significant reduction in our capital expenditures.”

Since initiating the deployment of the IGEL UDC and UMS software, UNC Health Care has also experienced significant time savings. “Prior to deploying the IGEL UDC and UMS software, it took our team 25-30 minutes to create a virtual image on each system, not counting the personalization of the system for each use case, now that process takes less than 10 minutes, and even less time when converting the system to VDI roaming,” added Cole.

Additionally, the ease of integration between the IGEL UDC and IGEL UMS with Citrix XenDesktop and other solutions offered by Citrix Ecosystem partners, including Imprivata, has enabled secure access to the health care network’s Epic Systems’ Electronic Medical Records (EMR) system.

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.
