Working with Windows Containers and Docker: Up and Running

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

Working with Windows Containers and Docker: The Basics

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

VMware Lab setup – A virtualized lab for testing HA and DRS

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 … Read more

Virtual Machine Storage Provisioning and Best Practises

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

Increasing the Availability of Virtualised Applications and Services

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

A Beginner’s Guide to Virtualizing Exchange Server, Part 2

It isn't easy to measure the consumption of physical resources by servers in virtual machines, since each partition has its' own virtualised view of system resources. Not only that, but there is a subtle difference between virtual processors and physical processors. Brien Posey explains the special performance counters that can be used to get an accurate assessment, and goes on to describe how to test your physical servers to see if they are good candidates for virtualization. … Read more

Windows Server Virtualisation: Hyper-V, an Introduction

For SQL Server and Exchange Server, Windows Server Virtualization is going to be increasingly important as a way for the administrator to allocate hardware resources in the most efficient way, to offer more robust services, and for deploying services. Jaap Wesellius starts his new series on Hyper-V by explaining what Hyper-V is, how it relates to Windows Server 2008 and how it compares to ESX, Virtual Server and Virtual PC. .… Read more
