Create Azure Dedicated Host

Azure Dedicated Host for your Azure VMs

Last week Ziv Rafalovich, Principal Program Manager in the Azure Compute team, announced the Azure Dedicated Host Public Preview. Azure Dedicated Host is a new Azure service which enables customers to run Windows and Linux virtual machines on single dedicated physical servers. Usually, the Azure host is used by multiple tenants, and the virtual machines are isolated using a multi-tenant hypervisor, with Azure Dedicated Host, the physical server only runs workloads from one tenant/customer. This gives customers the visibility and control on what physical hardware their virtual machines are running, and it allows to address corporate compliance and regulatory requirements.

Azure Dedicated Host Preview provides physical servers that host one or more Azure virtual machines. Your server is dedicated to your organization and workloads—capacity isn’t shared with other customers. This host-level isolation helps address compliance requirements. As you provision the host, you gain visibility into (and control over) the server infrastructure, and you determine the host’s maintenance policies.

You can find more information on Azure.com.

Azure Dedicated Host scenarios

The Azure Dedicated Host offers a couple of benefits and enables some new scenarios.

  • Host-level isolations for compliance requirements
  • Visibility and control over the server infrastructure to manage host maintenance policies, load on the server, fault domain count.
  • You get control over the full performance and capacity from a single Azure host which is not shared with other customers.
  • You get the advantage of unlimited virtualization for Windows Server and SQL Server with Azure Dedicated Hosts using the Azure Hybrid Benefit.

If you need these scenarios, then the Azure Dedicated host is an excellent option for you. However, if you don’t need them, you are more flexible with the shared Azure virtual machine experience.

Licensing and Pricing

Dedicated Hosts are charged at the host level and not on the number of Azure VMs you run on the host. However, software licenses are billed separately from compute resources at a VM level based on usage. There are no upfront costs or termination fees. Currently, the Azure Dedicated Host is a pay-as-you-go service, and you only pay for what you need.

You will have different dedicated host types and VM series/families available. During the preview period, you will be able to choose between Dsv3, Esv3, and Fsv2 VM series.

Dedicated Host Typ 1

Dedicated Host Type 1 is based on the 2.3 GHz Intel Xeon® E5-2673 v4 (Broadwell) processor and can achieve up to 3.5 gigahertz (GHz). Type 1 host has 64 available vCPUs.

    • Dsv3 Series
    • Esv3 Series

Dedicated Host Type 2

Dedicated Host Type 2 is based on the Intel Xeon® Platinum 8168 (Skylake) processor, which can achieve maximum single-core clock speeds of 3.7 GHz and sustained all core clock speeds as high as 3.4GHz with the Intel Turbo Boost Technology 2.0. Type 2 host has 72 available vCPUs.

    • Fsv2 Series

Dedicated Host configuration table

This is the Dedicated Host configuration table during the Public Preview. This might change later, and you can find the current pricing information on Azure.com.

Additional cost reduction

You can use your on-premises Windows Server and SQL Server licenses with Software Assurance benefits, or subscriptions with equivalent rights, when you migrate your workloads to Dedicated Host (Azure Hybrid Benefit).  Different the before is that with the dedicated host you get unlimited virtualization rights for Windows Server and SQL Server. For more information on the updated Microsoft licensing terms for dedicated hosted cloud services, check out this blog post. With this running Windows Server 2019 in Azure becomes even more attractive.

We are also expanding Azure Hybrid Benefit so you can take advantage of unlimited virtualization for Windows Server and SQL Server with Azure Dedicated Hosts. Customers with Windows Server Datacenter licenses and Software Assurance can use unlimited virtualization rights in Azure Dedicated Hosts. In other words, you can deploy as many Windows Server virtual machines as you like on the host, subject only to the physical capacity of the underlying server. Similarly, customers with SQL Server Enterprise Edition licenses and Software Assurance can use unlimited virtualization rights for SQL Server on their Azure Dedicated Hosts.

You’ll also get free extended security updates for Windows Server and SQL Server 2008 and 2008 R2.

Azure Reserved VM Instances are not available for purchase during the preview on Azure Dedicated Host.

Deploy VMs to an Azure Dedicated Hosts

To deploy a new Azure Dedicated Host, we first need to create a host group. After that, we can add hosts to this group, which will be used for our Azure virtual machines. In this blog post, I am going to show you how you can deploy a new host and after that, how you deploy Azure VMs on that host using the Azure portal. If you want to know more and if you want to see how you do this using Azure PowerShell, an Azure Resource Manager (ARM) template or the Azure CLI, check the Microsoft Docs.

Create a host group

Azure Host Groups

Azure Host Groups

You can find a new Azure resource called Host Group. Create a host group and configure the host group with specific settings like availability zones and fault domain count.

After you have created your host group, you can start creating new hosts and add them to your host group.

  • Select the location (region) of the host
  • Select the dedicated host VM family and hardware generation. You will only be able to provision VMs on this host in the same VM family. During the preview, we will support the following host SKU values: DSv3_Type1 and ESv3_Type1.
  • Configure the fault domain for the host.
  • Enable or disable of automatically replacing the host on a failure.
  • Configure cost savings like the Azure Hybrid Benefit.

Create Azure Dedicated Host

Your host will be deployed in a couple of minutes. Important, your Azure subscription will need to have enough resources (CPU/Cores) enabled. Some subscriptions are limited to a specific amount of cores you can deploy in your subscription, in that case, you will need to open a support ticket, to raise the number of cores available in your subscription.

Create a VM

Now you can create a virtual machine on the Azure Dedicated Host. There area few things to consider about that VM. First, make sure the VM is created in the region you have created the host. Secondly, choose a virtual machine size of the VM family you had configured when you created the host.

During the creation process, you will find the section Host in the Advanced tab. Here you can select your host group and your host where the VM will be deployed on.

For more information, check out the Microsoft Docs.

Conclusion

The Azure Dedicated Host service enables new scenarios and addresses, especially customers with host-level isolations for compliance requirements. It makes the Azure IaaS platform even more exciting, and together with Azure Migrate, you can quickly move your virtual machines to Azure. If you have any questions, feel free to leave a comment.

Docker Desktop WSL 2 Tech Preview

Run Linux Containers with Docker Desktop and WSL 2

Today, Docker launched the first Tech Preview of the Docker Desktop WSL 2. This means you can now use Docker Desktop and the Windows Subsystem for Linux 2 (WSL2) which is using the hypervisor in the background to run Linux containers on Windows 10. With the significant changes to the Windows Subsystem for Linux 2, you can now take advantage of these improvements with your Docker Desktop client.

Docker Desktop WSL 2 is currently in Tech Preview, and it also requires the Windows 10 Insider Preview builds. That means you should only use for not production environments.

WSL 2 introduces a significant architectural change as it is a full Linux kernel built by Microsoft, allowing Linux containers to run natively without emulation. With Docker Desktop WSL 2 Tech Preview, users can access Linux workspaces without having to maintain both Linux and Windows build scripts.

Docker Desktop also leverages the dynamic memory allocation feature in WSL 2 to greatly improve the resource consumption. This means, Docker Desktop only uses the required amount of CPU and memory resources, enabling CPU and memory-intensive tasks such as building a container to run much faster.

You can find more information about the Tech Preview here.

Prerequisites

To run the Docker Desktop WSL 2 Tech Preview, you will need to set up the Windows Subsystem for Linux 2 (WSL 2) first. You can do that using the following guide, or follow these steps:

Install Windows 10 Insider Preview build 18932 or later.

Install the Windows WSL feature and the Windows Virtual Machine Platform feature running the following commands:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
 
Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform

Download WSL Linux distribution based on Ubuntu 18.04 from the Microsoft Store. You can read more about Linux on Windows 10 here. The distribution needs to be set as the default WSL distro.

Enable Virtual Machine Platform

Enable Virtual Machine Platform

Make sure that the WSL distro is running in WSL 2 mode. You can check the list of distros installed on your Windows 10 machine, with the following PowerShell command:

wsl -l -v

To set the distro to WSL 2, you can run the following command. Change the name of the distro:

wsl --set-version DistroName 2
Install WSL 2

Install WSL 2

To find out more about installing WSL 2, check out the Microsoft Docs page.

How to set up Docker and WSL 2

First, you will need to download the Docker Desktop WSL 2 Tech Preview here. Make sure you already configured all the WSL 2 steps described in the prerequisites, before you install the Docker WSL 2 Tech preview. If you are prompted if you want to use Linux containers or Windows containers during the installation, select Windows containers. If you choose Linux containers, you will have the classic Docker experience with a Hyper-V VM.

Docker Desktop WSL 2 Tech Preview Menu

Docker Desktop WSL 2 Tech Preview Menu

Run the installation wizard, and after a successful installation, the Docker Desktop menu displays the WSL 2 Tech Preview option. You can select WSL 2 Tech Preview from that menu to start and configure the daemon running WSL 2.

SSH Remote Edit File with Visual Studio Code

Remote Edit Files on Azure Linux VMs using VS Code

There are a lot of different ways to remote manage your Azure virtual machines using various tools and technics. In this blog post, I am going to show you how you can remotely edit files on Azure Linux virtual machines using Visual Studio Code. Visual Studio Code has a new Remote Development Extention which allows you to open any folder in a container, on a remote computer, or in the Windows Subsystem for Linux (WSL) and take advantage of the VS Code feature set. With the Remote – SSH extensions, you can easily browse and edit files on an Azure VM or any other system where you can connect using SSH.

Installation

As mentioned to edit the files on the Azure Linux virtual machine remotely, we are using the light-weight, cross-platform, opensource editor Visual Studio Code. You can download and install VS Code from the official website.

Visual Studio Code Remote Development Extension

In addition to Visual Studio code, we need to install the Remote – SSH extension, which comes with Remote Development Extension Pack. This also includes remote extensions for containers or the Windows Subsystem for Linux (WSL).

If you are running on a Windows 10 machine, you will also need to install the OpenSSH client on your machine. You can do that going through this blog post, or by running this command.

# Install the OpenSSH Client
Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

Azure VM connection using SSH

The Remote – SSH extensions currently only supports connecting to x86_64 Linux-based SSH servers using key-based authentication.

Optional: Create Azure Linux VM with key-based SSH authentication using the Azure CLI

Create Azure Linux VM Azure CLI SSH Keys DNS Name

If you want to try it out, and you haven’t set up a Linux VM SSH and key-based authentication. This Azure CLI command here helps you to create a new Azure virtual machine and sets up ssh keys as well as an optional unique Azure DNS name.

az vm create --resource-group demosshvm --name tomsVM --image UbuntuLTS --admin-username thomas --generate-ssh-keys --public-ip-address-dns-name tomsazurelinuxvm

In this example, you can use the public IP address or the Azure FQDN to connect to the Azure VM. If you have a VPN or Express Route set up, you can also use private IP addresses and DNS names. If you are using public IP addresses in production, make sure you are using a service like Azure Just in Time VM access.

Connect Visual Studio Code to Azure VM using SSH

After you have installed Visual Studio Code, the Remote – SSH extension, the SSH client and have a VM with key-based authentication, you can now easily connect. Open Visual Studio Code, on the bottom left, you see the Remote connection button. If you press it, you will find the remoting options. Select “Remote-SSH: Connect to Host…

Visual Studio Open Remote SSH Connection

This will ask you for the username and IP address or DNS name of the virtual machine. In my case, I am going to use the DNS name.

Visual Studio Code SSH Remoting Connection

 

After pressing enter, this will connect your Visual Studio Code environment to the Azure virtual machine.

Visual Studio Code SSH Connection

 

Remote edit files on Azure Linux VMs using VS Code

You can start opening folders and files on the remote Azure Linux VM and begin browsing the file system. On the bottom left, you see the name or IP address of the machine you are connected with.

SSH Remote File System Visual Studio Code

You can also open files and start remote edit files on your Azure Linux VM. If you save the changes you made to the file, this is directly saved on the remote Azure virtual machine.

SSH Remote Edit File with Visual Studio Code

You get all the advanced VS Code features you know from your local Visual Studio Code like syntax-highlighting and more.

I hope this shows you an easy way to remotely edit files on your Azure Linux virtual machines using Visual Studio Code and SSH. If you have any questions, please let me know in the comments.



Hyper-V Server 2019 Install now

How to Install Hyper-V Server 2019

A couple of weeks ago Microsoft released the installation media, and you can download Hyper-V Server 2019 right now. In this blog post, I am going to show you how to install and configure Hyper-V Server 2019 step by step. This should especially help beginners with Hyper-V Server 2019. Hyper-V Server 2019 ships only a core option, so there won’t be desktop experience version of Hyper-V Server like you would have with Windows Server 2019.

Hyper-V Server 2019 Requirements

Hyper-V has specific hardware requirements to run virtualization in a secure and performant way.

  • 64-bit processor with second-level address translation (SLAT)
  • Minimum of 4GB of RAM. You will need more RAM for virtual machines on the Hyper-V Server.
  • Virtualization features and support needs to be enabled in BIOS or UEFI
    • Hardware-assisted virtualization – Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
    • Hardware-enforced Data Execution Prevention (DEP)  Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).

Specific features, like Discrete device assignment (DDA) or Shielded Virtual Machines, will also have other hardware requirements. You can find more about the Hyper-V Server 2019 requirements on Microsoft Docs.

Download ISO

You can download Hyper-V Server directly from the Microsoft evaluation center. This SKU does not require a license key, and it also doesn’t expire. It is a fully supported version of Hyper-V for free. However, if you run workloads like Windows Server, Windows 10, or other operating systems on top of it, they need to be correctly licensed.

Install Hyper-V Server 2019

After you have download the ISO file, you will need to install this on your machine. There are multiple options to do this:

You can also follow this guide to add drivers to a Windows Server Image; this also works for Hyper-V Server.

Now you can boot your server with the Hyper-V installation media. This will start the step by step installation. Select the language and region settings you want to use for your Hyper-V Server.

Install Hyper-V Server 2019

Install Hyper-V Server 2019
