How to navigate between the trenches
Hybrid IT has moved from buzzword status to reality and organizations are realizing its potential impact. Some aspects of your infrastructure may remain in a traditional setting, while another part runs on cloud infrastructure—causing great complexity. So, what does this mean for you? “A Journey Through Hybrid IT and the Cloud” provides insight on:
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!
If you’re here to gather some of the best practices surrounding vSphere, you’ve come to the right place! Mastering vSphere: Best Practices, Optimizing Configurations & More, the free eBook authored by me, Ryan Birk, is the product of many years working with vSphere as well as teaching others in a professional capacity. In my extensive career as a VMware consultant and teacher (I’m a VMware Certified Instructor) I have worked with people of all competence levels and been asked hundreds - if not thousands - of questions on vSphere. I was approached to write this eBook to put that experience to use to help people currently working with vSphere step up their game and reach that next level. As such, this eBook assumes readers already have a basic understanding of vSphere and will cover the best practices for four key aspects of any vSphere environment.
The best practices covered here will focus largely on management and configuration solutions so should remain relevant for quite some time. However, with that said, things are constantly changing in IT, so I would always recommend obtaining the most up-to-date information from VMware KBs and official documentation especially regarding specific versions of tools and software updates. This eBook is divided into several sections, and although I would advise reading the whole eBook as most elements relate to others, you might want to just focus on a certain area you’re having trouble with. If so, jump to the section you want read about.
Before we begin, I want to note that in a VMware environment, it’s always best to try to keep things simple. Far too often I have seen environments be thrown off the tracks by trying to do too much at once. I try to live by the mentality of “keeping your environment boring” – in other words, keeping your host configurations the same, storage configurations the same and network configurations the same. I don’t mean duplicate IP addresses, but the hosts need identical port groups, access to the same storage networks, etc. Consistency is the name of the game and is key to solving unexpected problems down the line. Furthermore, it enables smooth scalability - when you move from a single host configuration to a cluster configuration, having the same configurations will make live migrations and high availability far easier to configure without having to significantly re-work the entire infrastructure. Now the scene has been set, let’s get started!
Each version of Windows and Windows Server showcases new technologies. The advent of PowerShell marked a substantial step forward in managing those features. However, the built-in graphical Windows management tools have largely stagnated - the same basic Microsoft Management Console (MMC) interfaces had remained since Windows Server 2000. Microsoft tried out multiple overhauls over the years to the built-in Server Manager console but gained little traction. Until Windows Admin Center.
WHAT IS WINDOWS ADMIN CENTER?Windows Admin Center (WAC) represents a modern turn in Windows and Windows Server system management. From its home page, you establish a list of the networked Windows and Windows Server computers to manage. From there, you can connect to an individual system to control components such as hardware drivers. You can also use it to manage Windows roles, such as Hyper-V.
On the front-end, Windows Admin Center is presented through a sleek HTML 5 web interface. On the back-end, it leverages PowerShell extensively to control the systems within your network. The entire package runs on a single system, so you don’t need a complicated infrastructure to support it. In fact, you can run it locally on your Windows 10 workstation if you want. If you require more resiliency, you can run Windows Admin Center as a role on a Microsoft Failover Cluster.
WHY WOULD I USE WINDOWS ADMIN CENTER?In the modern era of Windows management, we have shifted to a greater reliance on industrial-strength tools like PowerShell and Desired State Configuration. However, we still have servers that require individualized attention and infrequently utilized resources. WAC gives you a one-stop hub for dropping in on any system at any time and work with almost any of its facets.

The primary goal of a multi-cloud data management strategy is to supply data, either via copying or moving data to the various multi-cloud use cases. A key enabler of this movement is the data management software applications. In theory, data protection applications can perform both of the copy and move functions. A key consideration is how the multi-cloud data management experience is unified. In most cases, data protection applications ignore the user experience of each cloud and use their proprietary interface as the unifying entity, which increases complexity.
There are a variety of reasons organizations may want to leverage multiple clouds. The first use case is to use public cloud storage as a backup mirror to an on-premises data protection process. Using public cloud storage as a backup mirror enables the organization to automatically off-site data. It also sets up many of the more advanced use cases.
Another use case is using the cloud for disaster recovery.
Another use case is “Lift and Shift,” which means the organization wants to run the application in the cloud natively. Initial steps in the “lift and shift” use case are similar to Dev/Test, but now the workload is storing unique data in the cloud.
Multi-cloud is a reality now for most organizations and managing the movement of data between these clouds is critical.
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!
Part 1 explains the fundamentals of backup and how to determine your unique backup specifications. You'll learn how to:
Part 2 shows you what exceptional backup looks like on a daily basis and the steps you need to get there, including:
Part 3 guides you through the process of creating a reliable disaster recovery strategy based on your own business continuity requirements, covering:
Managing Windows user profiles can be a complex and challenging process. Better profile management is usually sought by organizations looking to reduce Windows login times, accommodate applications that do not adhere to best practice application data storage, and to give users the flexibility to login to any Windows Operating System (OS) and have their profile follow them.
Note that additional profile challenges and solutions are covered in a related ProfileUnity whitepaper entitled “User Profile and Environment Management with ProfileUnity.” To efficiently manage the complex challenges of today’s diverse Windows profile environments, Liquidware ProfileUnity exclusively features two user profile technologies that can be used together or separately depending on the use case. These include:
1. ProfileDisk™, a virtual disk based profile that delivers the entire profile as a layer from an attached user VHD or VMDK, and
2. Profile Portability, a file and registry based profile solution that restores files at login, post login, or based on environment triggers.
Ransomware is a growing threat to every organization on the planet; it seems we cannot go a day without seeing another high-profile ransomware attack being detailed in mainstream media.
Cyber-criminals are innovating at a phenomenal pace in this growing ‘industry’ because they have the funds to do so. In fact many cyber-criminal groups have more funds than most enterprises.
The disruption these attacks are causing to businesses is huge with billions of dollars’ worth of revenue being lost due to system outages caused via ransomware attacks.
Research has shown that a 41% increase in attacks has occurred since the beginning of 2021 with a staggering 93% increase year over year.
Companies are getting hit via ransomware every day, but how does it get in? Some of the most common ways ransomware is getting in is via the following methods:
1. Phishing emails that launch ransomware attacks via inline links, links in attachments, or fake attachments.2. Browsing unknown links and websites.3. Downloading and accidentally running infected software.4. Inserting or connecting an infected disk, disc, or drive.5. Operating system based vulnerabilities if the OS is not patched to the latest levels.6. Plugin based vulnerabilities if plugins are not patched to the latest levels.7. Infrastructure vulnerabilities (network, storage etc.) if not patched to the latest levels.
With the shift in the computing paradigm to the cloud, the Azure ecosystem is quickly becoming a critical platform for IT pros to grasp and adopt. But how do you make the leap while maintaining security, manageability, and cost-control?
Whether you’re making new VMs directly in the cloud, have VMs in your own datacenter and are looking to migrate to Azure, or you’re looking to manage VMs with cloud-based tools regardless of where they live, The SysAdmin Guide to Azure Infrastructure as a Service (Iaas) will teach you to set up and maintain a high-performing Azure IaaS environment.
