With the latest release of Hyper-V, Microsoft has made some great improvements to their Hypervisor. For many reasons, Hyper-V has become a major player in virtualization. In this article, Nicolas Prigent describes new Hyper-V updates and enhanced Hyper-V features that were introduced with Windows 10 and Windows Server 2016.… Read more
So far, in this series, Nicolas has shown how to get simple container instances up and running with just some basic background information. Now we need to understand the differences between Linux containers, Windows Server containers and Hyper-V containers. We can then define, create and run multi-container Docker applications, and port existing Windows Container VMs to Docker.… Read more
Deployments can be made easier, in many different ways, by using Docker and Windows Containers; but how do you set about working with them? As part of his practical series on Windows Containers and Docker, Nicolas shows how to deploy a Container Host to the Microsoft Azure cloud. retrieve Images from Docker Hub, build your own container image, and push your images to the Docker Hub. … Read more
When you begin to work with containers, you will notice many similarities between a container and a virtual machine; but, in fact, these are two quite different concepts. Containers are going to change the way that we do Windows-based development work in the coming year, and they already underpin much of the devops work of speeding the delivery process. Nicolas Prigent explains how to use the Windows Containers feature.… Read more
Windows Server 2016 features support for containers. These are not Linux-based, but containers that run on Windows and run Windows on the inside.
These conform to the Open Container Initiative (OCI). They allow you to run applications insulated from the rest of the system, within portable containers that include everything an application needs to be fully functional. As they did with Linux, containers will change the nature of the software supply chain for Windows users.… Read more
A Hyper-V replica installation provides rapid disaster-recovery by asynchronously replicating a VM running at a primary site to a replica site. Know how to prepare for something to go wrong at the Primary Server/Site? In this article Nirmal Sharma presents the Replication options for a Replica Virtual Machine with a focus on Hyper-V Failover.

A Hyper-V replica installation provides a great opportunity for providing rapid disaster-recovery by asynchronously replicating a VM running at a primary site to a replica site across LAN or WAN to maintain a hot standby VM. Nirmal explains more, and shows how to set it up.… Read more
Hyper-V has become far more sophisticated since the release V3 of Windows 2012, but it means that there are now a number of alternative ways of achieving migration and High-availability. The right method depends on your particular requirements, as Nirmal explains.… Read more
A configuration of Hyper-V networking across two or more Hyper-V Hosts is the most complex type. It needs to be configured according to the business rules and communication between Virtual Machines and the Hyper-V Parent Partition is best configured with VMBUS and VSP/VSC components. Nirmal explains how best to do it… Read more
Hyper-V Networking can be configured to meet a wide range of requirements, but it isn't always obvious which choices are appropriate when configuring the virtual network, and in particular the best ways to implement Virtual Network Switches.… Read more
VMWare VSphere is a virtualisation technology that is best learned by setting up, on a single PC, a VSphere cluster as a virtualisation lab. Once you have it, it will then be a useful tool in many ways. This doesn't need to be an expensive exercise, but can be daunting if you don't have a simple guide to talk you through the process. Here, Sean provides that simple guide

If you need to test new software, configurations, or operating systems, a virtual machine saves time, risk and hardware. You can set up a virtual Test environment for free with some products such as VMware Server 2. All you need is a simple set of instructions about how to set it up; and here it is, thanks to Sean Duffy.… Read more
If you're working with Hyper-V, it's recommended that you use Windows Server 2008 R2 Server Core for your root partition, as its stripped-down nature makes it a more secure option than it's more full-bodied sibling. But it can also be painful to work with. Jaap Wesselius expertly guides us through the pitfalls.… Read more
Virtualization is a powerful technology, but it comes with its own host of monotonous and time-consuming tasks, no matter how big or small your organization is. Eliminating these mind-numbing tasks (and the potential for error which they bring with them) is a goal with striving for, and well within your reach. Jonathan Medd explains.… Read more
If you're using virtualization technology, then at some point you'll have run out of (or will run out of) virtual disk space, leading to the provisioning of extra storage; are you confident that you know how to do that? Sean Duffy makes sure you're doing it right, sharing his recommendations and tips in this step-by-step guide. Follow this advice, and you'll be a virtualization veteran in no time.… Read more
Reliability is one of the great payoffs to virtualization, and failover clustering has got a whole lot better with Windows Server 2008 and Hyper-V. Now, you get failover without any downtime for the virtual machine. Jaap tells you how to implement it.… Read more
The chore of patching operating systems and applications is taking an increasing proportion of the time of a system administrator, so it is a a relief that at least VMware is keen to make the task easier. VMware provide a tool in vCenter Update Manager to assist in keeping VMware up to date. Jonathan Medd explains all.… Read more
The dream of an 'office in a box' has been around for years, but the increasing sophistication of virtualization software has turned the dream into reality. Ben Lye explains the problems and benefits of reducing the amount of physical hardware that were deployed in his organisation's regional offices.… Read more
In the first of a series of articles on Hyper-V Networking, Nirmal explains Hyper-V networking and VLAN tagging, and shows how to set up a Virtual Network switch. Once this is done, the Hyper-V Virtual Network Switches can be used to connect unlimited no. of Virtual Machines. … Read more
By using a virtualized clustering computing environment with failover, you can improve server availability without using as many physical computers. A group of independent computers can work together to increase the availability of virtualised applications and services. If one of the cluster nodes fails, another node takes over to provide the service without disrupting the service. Nirmal Sharma explains the failover process under Hyper-V and how to improve the performance of a failover.… Read more
