Nano Server – The future of Windows Server – Just enough OS

Share on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInPin on PinterestShare on TumblrShare on RedditEmail this to someone

Finally, Microsoft released Windows Server 2016 and with Windows Server 2016 we also get the first version of Nano Server. I had the opportunity to speak on several different events and conferences about Nano Server, so I tried to create a quick summary of my presentation in this blog post.

Nano Server installation option Just enough OS

Nano Server - Just enough OS

Nano Server is a redesign version of Windows Server which is very lightweight, very small footprint and fully remote managed and it is designed to solve some of the datacenter challenges we have today. Nano Server is a headless, 64-bit only deployment option of Windows Server. Microsoft basically removed all components from the base image. Roles and feature are not directly included in the base image and they have to be added while creating a new Nano Server Image or online using PowerShell Package Management. Not even the drivers are included in the base image, since you don’t want the physical drivers in a virtual machines, and you don’t want the virtual drivers on a physical machine This is also the reason why Nano Server does not show up during the installation dialog when you boot the Windows Server 2016 ISO file.

Nano Server Key Scenarios

The first version of Nano Server is designed for the following key scenarios:

  1. Born-in-the-cloud applications – support for multiple programming languages and runtimes. (e.g. ASP.NET Core, C#, Java, Node.js, Python, etc.) running in containers, virtual machines, or on physical servers.
  2. Microsoft Cloud Platform infrastructure – support for compute clusters running Hyper-V and storage clusters running Scale-out File Server and Storage Spaces Direct.
  3. But Microsoft also added some other roles like DNS and IIS to the Nano Server and we can expect more roles and features in the future.

In this version Nano Server will of course not replace Windows Server Core and Windows Server (Full or Server with Desktop Experience), but it will be definitely be they way going forward.

Nano Server Footprint

Nano Server has a very small foot print, The default WIM file has a size around 170 MB and if you create a Nano Server VHD or VHDX file it can be only around 400 MB in size. If you add more roles, features and drivers the size of the image gets bigger, but even if you add more stuff the size will be around 800 MB for an Hyper-V server including the Hyper-V role, Failover Clustering Feature, DCB feature, Physical OEM drivers and additional network adapter and storage controller drivers. If you compare Nano Server to Windows Server you can see some of the following changes:

  • 93 percent lower VHD size
  • 92 percent fewer critical bulletins
  • 80 percent fewer reboots

Nano Server Servicing Improvements

Nano Server Servicing Improvments

Nano Server Deployment Improvements

Nano Server Deployment Improvments

This not only reduced deployment time and gives you some operational improvements, it also reduces the attack surface by a lot and this is a huge security improvement.

To achieve these results, Microsoft removed some parts of Windows Server such as:

  • GUI stack
  • 32 bit support (WOW64)
  • MSI support
  • RDP
  • Some default Server Core components
  • Basic OEM Drivers
  • and more

Nano Server Management

By removing the User Interface stack, Microsoft made this server to a true headless server, without any login screen or RDP support. By removing the Graphic User Interface, Windows Administrator have to learn new ways how they manage servers, or better use existing ways to manage a Nano Server environment. The answer is simple and is the best practice for managing servers for a long time called Remote Management. Nano Server will offer some advanced remote Management features such as:

  • WMI
  • PowerShell Remoting
  • PowerShell Direct
  • PowerShell Desired State Configuration
  • RSAT Tools (Server Manager, Hyper-V Manager, Failover Cluster Manager, …)
  • System Center and other Management tools
  • Server Management Tools (Azure Web-based management tools to replace local inbox management tools)

With that, existing Remote Management Tools, such as Server Manager and other RSAT tools, will continue to work. But Microsoft also improved PowerShell Remoting and introduces the Azure Serivce for Server Management Tools.

Server Management Tools

Microsoft Azure Server Management Tools Topology

This service allows you to manage your servers directly from Azure using a web-based HTML5 portal. I personally think that this could also replace Server Manager and allows you to easily manage non-GUI servers such as Windows Server Core and Nano Server.

Azure Remote Server Management Nano Server

If you want to know more about the Sever Management Tools, check out my blog post: Manage Nano Server and Windows Server from Azure using Remote Server Management Tools

The Server Management Tools do not only support Nano Server, they also support Windows Server 2016, Windows Server 2012 R2 and Windows Server 2012 with WMF 5.0 and higher.

Remote Manage Nano Server with PowerShell

Nano Server PowerShell Remoting

The simplest way to manage Nano Server is by using PowerShell Remoting using for exmaple the following command.

If you are directly on a Hyper-V Server you can also use PowerShell Direct which allows you to directly connect to a Virtual Machine using the Hyper-V VMBus.

If you want to know more about Managing Nano Server check out the following blog posts How to Remote Manage your Nano Server using PowerShell or Hyper-V PowerShell Direct.

Manage Nano Server using System Center

Nano Server can also be managed using System Center Virtual Machine Manager and System Center Operations Manager. With SCVMM you can deploy new Hyper-V and Storage Spaces Direct hosts as well as Virtual Machines.

Deploy Nano Server

To deploy Nano Server as a virtual machine or as a physical host you have to create a new Nano Server Image. For this you have basically have two option. The first one is using the built in Nano Server Image Generator PowerShell module and the second option is the Nano Server Image Builder UI wizard.

Nano Server Image Generator PowerShell module

New-NanoServerImage

The Nano Server Image Generator PowerShell module allows you to create new Nano Server Images. You can find this on the Windows Server 2016 media in the Nano Server folder. Here is a quick example how to create a new VHDX using the PowerShell module.

Nano Server Image Builder

Nano Server Image Builder

The Nano Server Image Builder is a UI based wizard to create Nano Server Images in VHDX, VHD, WIM or ISO to install Nano Server on all possible systems.

The Nano Server Image Builder can help you with the following tasks:

  • Graphical UI to create Nano Server Images
  • Adding drivers
  • Choose Windows Server Edition
  • Adding roles and features
  • Adding drivers
  • Adding updates
  • Configuration of Network Settings
  • Configuration of Domain settings
  • Set Remoting Options
  • Create an ISO file to boot from DVD or BMC (remote connection like HP ILO)

First download and install the Windows Assessment and Deployment Kit (ADK) and the Nano Server Image Builder.

If you need more information about deploying Nano Server check my blog post about Create a Nano Server using the Nano Server Image Builder and How to create a Nano Server Image using PowerShell.

Nano Server Packages

Nano Server Packages

Roles, Features and Drivers live outside of the basic Nano Server Image have to be added while creating the Nano Server Image or after that using PowerShell Package Management.

You can find and install Windows Packages from the online package repository by using the NanoServerPackage provider of PackageManagement (OneGet) PowerShell module.

Troubleshooting Nano Server

Nano Server Recovery Console

Hyper-V Nano Server Console

When you boot Nano Server you can not really login to Nano Server and browse the file system. What you can do is login to the Nano Server Recovery Console which allows you to do some basic tasks:

  • Shows computer info like Name, IP Configuration, OS Version and more
  • Reset Networking to DHCP
  • Reset basic Windows Firewall rules
  • If the Server is a Hyper-V Server you can see the VM running on the system and remove the Virtual Switch

Sysinternals for Nano Server

Sysinternals for Nano Server

There is also a Sysinternals version for Nano Server.

Nano Server over a serial port with Emergency Management Services

Emergency Management Services (EMS) lets you perform basic troubleshooting, get network status, and open console sessions (including CMD/PowerShell) by using a terminal emulator over a serial port. This replaces the need for a keyboard and monitor to troubleshoot a server.

You can include this using the following cmdlets

Nano Server Servicing

Nano Server Servicing

Windows Server are usually from the Long Term Servicing Branch and have 5 + 5 years of servicing and only get security and quality fixes, no new features. In Windows Server 2016 Server Core and Server with Desktop Experience follow this traditional servicing model. Nano Server on the other hand will be in a new servicing branch called Current Branch for Business (CBB).

  • Nano Server will not have an LTSB with Windows Server 2016 and therefore not have 5+5 years of servicing
  • Nano Server installations will have to move forward to future CBB releases of Nano Server to continue to be serviced
  • Licensing Nano Server will require Software Assurance (SA)
  • Installation of new CBBs are always controlled by administrators, no forced upgrades

Nano Server Key Wins

  • Easy and fast to deploy
  • Lightweight
  • Easily integrates with our automated approach
  • Reduces attack surface
  • Works with existing deployment tools (WDS, SCVMM, SCCM and boot from VHDX)
  • Reduces operational overhead
  • Highly stable
  • Delivers on scale and performance

Conclusion

In my opinion the effort Microsoft does with Nano Server really makes sense and will help Service Providers as well as Enterprise companies to deploy clouds even faster, more secure, more efficient and with less management overhead. Of course it is still early and Nano Server may not fit every case and scenario today, but definitely in the future.

Hyper-V Nano Server Console

How to deploy Nano Server

Share on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInPin on PinterestShare on TumblrShare on RedditEmail this to someone

Two weeks Microsoft released Windows Server 2016 and with that the first version of Nano Server. Now in this blog post I want to quickly show you how you can deploy Nano Server in Virtual Machines or on Physical Servers. Nano Server is following the zero-footprint model, so know roles and features as well as no drivers are included by default. With this you always have to create a new Nano Server Image and include the physical drivers or the virtual machine drivers and of course the roles and features.

To create new Nano Server Images you have basically two options, you can choose between the Nano Server Image Generator PowerShell module or the Nano Server Image Builder UI tool. With both you can create VHD, VHDX and WIM files which can be used to deploy Nano Server.

Create a Nano Server Image using the Nano Server Image Generator PowerShell module

New-NanoServerImage

This is the built in PowerShell module which can be found on the Windows Server 2016 media in the Nano Server folder.

  • MediaPath – The location with the Windows Server 2016 files
  • BasePath – Temporary folder to mount the WIM file
  • TargetPath – Where the new Image file gets stored. You can create a .wim, .vhd or .vhdx file
    • .vhd creates a Image for a Generation 1 VM (BIOS boot)
    • .vhdx create a Image for a Generation 2 VM (UEFI boot)
  • DeploymentType allows you to choose between Guest and Host
    • Guest creates a Virtual Machine
    • Host creates a Physical Image
  • Edition can be Standard or Datacenter
  • ComputerName adds the server name of the Nano Server
  • MaxSize changes the Partition size, if you are not using this parameter it will create a default partition of 4GB

This post shows you how you can install a VPN Server on Windows Server 2016 Step-by-Step. It shows you how you can easily setup a VPN server for a small environment or for a hosted server scenario.

This is definitely not a guide for an enterprise deployment, if you are thinking about a enterprise deployment you should definitely have a look at Direct Access.

I already did similar blog posts for Windows Server 2008 R2, Windows Server 2012 and Windows Server 2012 R2.

You can simply follow this step by step guide:

First install the “Remote Access” via Server Manager or Windows PowerShell.

Install Remote Access Role VPN

Select the “DirectAccess and VPN (RAS)” role services and click next.

Share on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInPin on PinterestShare on TumblrShare on RedditEmail this to someone

Last week Microsoft released Windows Server 2016 to the public and at the weekend Microsoft released the Nano Server Image Builder. I already wrote a few blog posts how you can create new Nano Server Images using PowerShell. The Nano Server Image Builder is a UI based wizard to create new Nano Server Images. The Nano Server Image Builder helps you create a custom Nano Server image and bootable USB media with a graphical interface. Based on the inputs you provide, it generates images for deployment and it also creates reusable PowerShell scripts that allow you to create installations of Nano Server.

The Nano Server Image Builder can help you with the following tasks:

  • Graphical UI to create Nano Server Images
  • Adding drivers
  • Choose Windows Server Edition
  • Adding roles and features
  • Adding drivers
  • Adding updates
  • Configuration of Network Settings
  • Configuration of Domain settings
  • Set Remoting Options
  • Create an ISO file to boot from DVD or BMC (remote connection like HP ILO)

First download and install the Windows Assessment and Deployment Kit (ADK) and the Nano Server Image Builder.

I will not go trough all the options but here is just quickly how you can use it.

First create a new Nano Server Image (this can be a VHD, VHDX or WIM file. If you want to use it on a USB drive or ISO save it as a WIM file)

Nano Server Image Builder

Make sure you have prepared everything like the Windows Server 2016 files and drivers etc

Prepapre Nano Server Files

Select the Windows Server 2016 source
