Introduction

There are lots of posts regarding Hyper-V networking. But there doesn’t seem to be a single compiled and up to date guide covering fundamentals and some advanced topics alike. This article aims to fill that gap, without a wall of text but a few easy to understand diagrams, tables, and PowerShell snippets. We will take a look at Hyper-V’s basic networking concept, NIC teaming (Network Interface Card) and different approaches to let VMs (Virtual Machines) talk to specific VLANs or even VLAN trunks.

The first article in the Hyper-V Networking 101 series will cover everything you need to know about virtual switches and NICs. The last post is planned as a real-world example: A way to implement a secure Wi-Fi (and/or wired) guest network on top of a virtual firewall.

Windows Server 2016 Nano Server – Installation and Management

Time to continue our conversation about that “scaled down even further” Server 2016 installation option. In my previous article, I covered general concepts around Nano Server, now I want to switch gears and talk about more practical aspects: installation and management. At the end of the day, you would agree that the best way to learn new technology it is trying to use it – this way you will be exposed to its strengths and weaknesses directly, and can get the real understanding of whether it works for you or not. Though at this point even Microsoft admits that despite all its greatness, at the moment, Nano Server has quite limited utility as it supports only a small subset of roles and features out of those which you can find in full GUI version of Windows Server.

Azure Container Service

Azure Container Service is a new technology, on Microsoft Azure, and that help you to deploy quickly and in production, with the ARM technology, a Docker cluster, orchestrated by Marathon and DC/OS, Docker Swarm, or Kubernetes to give your applications highly available, but also to deploy many nodes quickly and without any problems. The Microsoft’s documentation is available here: https://docs.microsoft.com/en-us/azure/container-service/container-service-intro

How can you Leverage the Azure Security Center and the Vulnerability Assessment
Posted by Augusto Alvarez on December 26, 2016
5/5 (2)

We’ve discussed in previous posts about Azure and the security topic as being one of the most critical ones for customers and therefore to Microsoft as well. Because of that, the Redmond based company has been including several new enhancements and features into Azure Security Center. One of the latest is the integrated vulnerability assessmentAzure Security Center

VMworld Europe 2016 main announcements – all you need to know about new versions of VMware products in just one article
Posted by Alex Samoylenko on November 1, 2016
4.5/5 (4)

Just recently one of the main virtualization conferences VMworld Europe 2016 has finished. Traditionally, it has been held a while after the main VMworld in the USA. While in the USA VMware was speaking about the new technologies and the future of datacenters, in Europe much more attention was paid to the new features of updated VMware products. The main of them is, of course, VMware vSphere 6.5 server virtualization platform. We’ll start our overview with it.

Introduction

Security is a critical requirement of any organization’s system. With the release of Windows Server 2016, Microsoft puts a lot of efforts around security and added a lot of new features. One hot feature that will add a lot of benefits to any small, medium and enterprise business environments is Shielded Virtual Machines and Key Storage Drive (KSD). Be sure that’s going to help you to increase the security whether you are a service provider or enterprise customer.

How VMware sees IT future. VMworld 2016. Day 1.
Posted by Alex Samoylenko on September 1, 2016

As you know, the main virtualization conference VMworld 2016 arranged by VMware is now being held in Las Vegas. On the first day of the conference several interesting announcements were made. For example, VMware Cloud Foundation, which soon will be available on the IBM platform and later with other vendors, as well, was presented. It allows to get a ready-made infrastructure at customer’s site with both necessary software and hardware components and ready, configured and integrated control and automation tools like NSX, Virtual SAN and vRealize:

vSphere Replication traffic isolation
Posted by Askar Kopbayev on July 27, 2016
4.25/5 (4)

vSphere Replication has proved to be a great bonus to any paid vSphere license. It is an amazing and simple tool that provides cheap and semi-automated Disaster Recovery solution. Another great use case for vSphere Replication is migration of virtual machines.

vSphere Replication 6.x came with plenty of new useful features:

  • Network traffic compression to reduce replication time and bandwidth consumption
  • Linux guest OS quiescing
  • Increase in scalability – one VRA server can replicate up to 2000 virtual machines
  • Replication Traffic isolation – that is what we are going to talk today.

The goal of traffic separation is to enhance network performance by ensuring the replication traffic does not impact other business critical traffic. This can be done either by using VDS Network Input Output Control to set limits or shares for outgoing or incoming replication traffic. Another benefit of traffic isolation addresses security concern of mixing sensitive replication traffic with other traffic types.

VMware Photon OS + Docker Volume Driver = containers architecture on vSphere virtualization platform
Posted by Alex Samoylenko on July 4, 2016
4.33/5 (3)

Many of you know that VMware has a technology called vSphere Integrated Containers (VIC). It involves launch of Docker (and others) virtualized containers in small virtual machines with a lightweight operating system based on Linux distribution.

This operating system is VMware Photon OS 1.0, which has been finally released just recently. This is the first release version of this operating system from VMware, but in the long view it can become the main platform for virtual appliances by replacing the everlasting SUSE Linux.

Manage storage QoS Policies from VMM 2016
Posted by Romain Serre on June 17, 2016
5/5 (1)

The QoS policy was a feature included in Windows Server 2012 R2 that enabled to set a minimum and a maximum IOPS on a VHD(X). These policies were not centralized and you had to set the QoS policy on each VHD(X) independently.

In Windows Server 2016, Microsoft has improved this feature because the policy can now be stored in the cluster database. You can create a policy based on a minimum / maximum IOPS and/or a bandwidth. This policy can be applied to a VHD(X) (Dedicated Policy Type) or to a set of VHD(X) (Aggregated policy Type).
