A2U, an IGEL Platinum Partner, recently experienced a situation where one of its large, regional healthcare clients was hit by a cyberattack. “Essentially, malware entered the client’s network via a computer and began replicating like wildfire,” recalls A2U Vice President of Sales, Robert Hammond.
During the cyberattack, a few hundred of the hospital’s PCs were affected. Among those were 30 endpoints within the finance department that the healthcare organization deemed mission critical due to the volume of daily transactions between patients, insurance companies, and state and county agencies for services rendered. “It was very painful from a business standpoint not to be able to conduct billing and receiving, not to mention payroll,” said Hammond.
Prior to this particular incident, A2U had received demo units of the IGEL UD Pocket, a revolutionary micro thin client that can transform x86-compatible PCs and laptops into IGEL OS-powered desktops.
“We had been having a discussion with this client about re-imaging their PCs, but their primary concern was maintaining the integrity of the data that was already on the hardware,” continued Hammond. “HIPAA and other regulations meant that they needed to preserve the data and keep it secure, and we thought that the IGEL UD Pocket could be the answer to this problem. We didn’t see why it wouldn’t work, but we needed to test our theory.”
When the malware attack hit, that opportunity came sooner, rather than later for A2U. “We plugged the UD Pocket into one of the affected machines and were able to bypass the local hard drive, installing the Linux-based IGEL OS on the system without impacting existing data,” said Hammond. “It was like we had created a ‘Linux bubble’ that protected the machine, yet created an environment that allowed end users to quickly return to productivity.”
Working with the hospital’s IT team, it only took a few hours for A2U to get the entire finance department back online. “They were able to start billing the very next day,” added Hammond.
This eBook explains how to identify problems with vSphere and how to solve them. Before we begin, we need to start off with an introduction to a few things that will make life easier. We’ll start with a troubleshooting methodology and how to gather logs. After that, we’ll break this eBook into the following sections: Installation, Virtual Machines, Networking, Storage, vCenter/ESXi and Clustering.
ESXi and vSphere problems arise from many different places, but they generally fall into one of these categories: Hardware issues, Resource contention, Network attacks, Software bugs, and Configuration problems.
A typical troubleshooting process contains several tasks: 1. Define the problem and gather information. 2. Identify what is causing the problem. 3. Fix the problem, implement a fix.
One of the first things you should try to do when experiencing a problem with a host, is try to reproduce the issue. If you can find a way to reproduce it, you have a great way to validate that the issue is resolved when you do fix it. It can be helpful as well to take a benchmark of your systems before they are implemented into a production environment. If you know HOW they should be running, it’s easier to pinpoint a problem.
You should decide if it’s best to work from a “Top Down” or “Bottom Up” approach to determine the root cause. Guest OS Level issues typically cause a large amount of problems. Let’s face it, some of the applications we use are not perfect. They get the job done but they utilize a lot of memory doing it.
In terms of virtual machine level issues, is it possible that you could have a limit or share value that’s misconfigured? At the ESXi Host Level, you could need additional resources. It’s hard to believe sometimes, but you might need another host to help with load!
Once you have identified the root cause, you should assess the impact of the problem on your day to day operations. When and what type of fix should you implement? A short-term one or a long-term solution? Assess the impact of your solution on daily operations. Short-term solution: Implement a quick workaround. Long-term solution: Reconfiguration of a virtual machine or host.
Now that the basics have been covered, download the eBook to discover how to put this theory into practice!

Scripting and PowerCLI are words that most people working with VMware products know pretty well and have used once or twice. Everyone knows that scripting and automation are great assests to have in your toolbox. The problem usually is that getting into scripting appears daunting to many people who feel like the learning curve is just too steep, and they usually don't know where to start. The good thing is you don't need to learn everything straight away to start working with PowerShell and PowerCLI. Once you have the basics down and have your curiosity tickled, you’ll learn what you need as you go, a lot faster than you thought you would!
ABOUT POWERCLI
Let's get to know PowerCLI a little better before we start getting our hands dirty in the command prompt. If you are reading this you probably already know what PowerCLI is about or have a vague idea of it, but it’s fine you don’t. After a while working with it, it becomes second nature, and you won't be able to imagine life without it anymore! Thanks to VMware's drive to push automation, the product's integration with all of their components has significantly improved over the years, and it has now become a critical part of their ecosystem.
WHAT IS PowerCLI?
Contrary to what many believe, PowerCLI is not in fact a stand-alone software but rather a command-line and scripting tool built on Windows PowerShell for managing and automating vSphere environments. It used to be distributed as an executable file to install on a workstation. Previously, an icon was generated that would essentially launch PowerShell and load the PowerCLI snap-ins in the session. This behavior changed back in version 6.5.1 when the executable file was removed and replaced by a suite of PowerShell modules to install from within the prompt itself. This new deployment method is preferred because these modules are now part of Microsoft’s Official PowerShell Gallery. 7 These modules provide the means to interact with the components of a VMware environment and offer more than 600 cmdlets! The below command returns a full list of VMware-Associated Cmdlets!
There are many new challenges, and reasons, to migrate workloads to the cloud.
For example, here are four of the most popular:
Whether it is for backup, disaster recovery, or production in the cloud, you should be able to leverage the cloud platform to solve your technology challenges. In this step-by-step guide, we outline how GCP is positioned to be one of the easiest cloud platforms for app development. And, the critical role data protection as-as-service (DPaaS) can play.
The cloud computing era is well and truly upon us, and knowing how to take advantage of the benefits of this computing paradigm while maintaining security, manageability, and cost control are vital skills for any IT professional in 2020 and beyond. And its importance is only getting greater.
In this eBook, we’re going to focus on Infrastructure as a Service (IaaS) on Microsoft’s Azure platform - learning how to create VMs, size them correctly, manage storage, networking, and security, along with backup best practices. You’ll also learn how to operate groups of VMs, deploy resources based on templates, managing security and automate your infrastructure. If you currently have VMs in your own datacenter and are looking to migrate to Azure, we’ll also teach you that.
If you’re new to the cloud (or have experience with AWS/GCP but not Azure), this book will cover the basics as well as more advanced skills. Given how fast things change in the cloud, we’ll cover the why (as well as the how) so that as features and interfaces are updated, you’ll have the theoretical knowledge to effectively adapt and know how to proceed.
You’ll benefit most from this book if you actively follow along with the tutorials. We will be going through terms and definitions as we go – learning by doing has always been my preferred way of education. If you don’t have access to an Azure subscription, you can sign up for a free trial with Microsoft. This will give you 30 days 6 to use $200 USD worth of Azure resources, along with 12 months of free resources. Note that most of these “12 months” services aren’t related to IaaS VMs (apart from a few SSD based virtual disks and a small VM that you can run for 750 hours a month) so be sure to get everything covered on the IaaS side before your trial expires. There are also another 25 services that have free tiers “forever”.
Now you know what’s in store, let’s get started!
The driving force for organizations today is digital transformation, propelled by a need for greater innovation and agility across enterprises. The digital life-blood for this transformation remains computers, although their form-factor has changed dramatically over the past decade. Smart devices, including phones, tablets and wearables, have joined PCs and laptops in the daily toolsets used by workers to do their jobs. The data that organizations rely on increasingly comes from direct sources via smart cards, monitors, implants and embedded processors. IoT, machine learning and artificial intelligence will shape the software that workers use to do their jobs. As these “smart” applications change and take on scope, they will increasingly be deployed on cloud infrastructures, bringing computing to the edge and enabling swift and efficient processing with real-time data.
Yet digital transformation for many organizations can remain blocked if they do not start changing how their workspaces are provisioned. Many still rely on outmoded approaches for delivering the technology needed by their workers to make them productive in a highly digital workplace.In this paper, Liquidware presents a roadmap for providing modern workspaces for organizations that are undergoing digital transformation. We offer insights into how our Adaptive Workspace Management (AWM) suite of products can support the build-out of an agile, state-of-the-artworkspace infrastructure that quickly delivers the resources workers need, on demand. AWM allows this infrastructure to be constructed from a hybrid mix of the best-of-breed workspace delivery platforms spanning physical, virtual and cloud offerings.
