Will outsourcing IT to us benefit your business?
- Your business is not in technology services provisioning?
- You find technology management time consuming and have higher priorities to deal with?
- There is too much to have to be an expert in when it comes to business technology?
- Technology decisions often don’t get made until they become major issues?
- Technology is more than just a convenience in your business. It enables your business processes and protects your market position?
- Multiple parties provide services upon a common infrastructure, your network?
- Architecture a supportive technology architecture based on business goals and best practices is beyond the capability of part-time technology stakeholders (the director who has technology as a portfolio responsibility, but is probably not a dedicated IT Director)?
- Employing IT staff is too expensive?
- Dealing with IT staff leave coverage and HR issues is a drain on your resources?
- Keeping technology staff appropriately trained and aligned to business benefits is too complicated?
- Complicated and expensive recruitment processes make employing IT staff a virtual minefield?
- IT Directors are not architects, architects won’t do IT support and technicians are not architects or IT Directors (but they may tell you that they are)

What is the Microsoft Nano Server and What are the Benefits of use
This will be the
Future Operating System which we are installing in our Datacenter. As of right
now, it is targeted as an OS for born-in-the-cloud applications and cloud
OS. The majority of Company corporate strategy is a concerted push toward the cloud,
whether it's public, private, or a hybrid cloud environment. Nano Server is
another key component of Microsoft's strategy to be highly competitive in the
private cloud market. Nano Server, a stripped down version of Windows Server
2016 that's designed specifically for cloud environments.
Unlike Server Core,
Nano Server is intended to be a completely headless installation (no local UI
and no local console). Also, where the Windows UI can be installed on top of
Server Core, Nano Server has no such capability.
What are the Benefits Of Microsoft Nano Server
1. Secure Server
The attack surface
is much smaller now. There is no Internet Explorer, no Windows Explorer, and no
GUI to exploit. Also, the default ports open with a base install is 12 as
opposed to 34 ports open by default with a full Windows GUI Server install.
This makes Nano Server a much more secure OS than its predecessors.
2. Costs
Because this server
creates such little overhead, the amount of resources needed to run Nano Server
VMs on a Hyper-V host will be miniscule. With its potential to lower costs and
increase margins, this will be one of the biggest reasons for companies to use
Nano Server VMs whenever appropriate. Allowing companies to get the most out of
every dollar spent on hardware is huge.
3. Faster boot times
Nano Server is only
installed with the components that are going to be used, so the startup time is
significantly faster. The boot IO is around 150MB. In fact, at Microsoft Ignite
when Snover presented a demo of a Hyper-V Nano Server cluster, the servers were
powering up faster than the switch was!
4. Fewer reboots
required
IT Admins will no
longer be frustrated by unnecessary reboots caused by patching windows
components that aren’t even used on their servers. Since only the components
needed are installed, the amount of patches and updates that are pushed out to
Nano Server will be much less. With the current Nano Server build, the
estimated amount of reboots a year are 3, and Microsoft is working diligently
to try to get this down to 2. Fewer reboots on Hyper-V hosts and their
VMs means less interruptions, which also means less “after hours” work for
some environments.
5. Easier remote
management
With Nano Server
there is no local logon, it will be managed entirely remotely. This direction
on Microsoft’s part requires them to focus on improving the remote
administration capabilities of Windows Server. They have recently been working
on improving some of the remote management aspects that were previously
lacking. For example, as part of the Azure stack, there is now a remote task
manager that allows admins to connect to VMs and view performance and processes
running. This will benefit IT Admins by improving the remote administration
experience when managing Hyper-V hosts and VMs.
6. Smaller server
image
Nano Server is 20x
smaller than the full Windows Server with a GUI. Because of this, storing Nano
Server VMs on a SAN or Hyper-V local storage will not consume large amounts of
space. Mass deployments of Nano Server VMs will not take as long to
install and configure; and copying server images over to Hyper-V nodes will
take less time. The small footprint of this OS is what really makes it shine.
Nano Server Use Cases
The obvious downside
of having a stripped-down version of Windows Server is that it has limited
capabilities. At this time, Nano Server supportability and compatibility we can
listed as below.
Role/Feature
- Hyper-v
- Failover Clustering
- File Server and Storage
- Internet Information Server (IIS)
- Desired State Configuration (DSC)
- System center Agent
- DNS Server
- Secure Startup
- Shielded VM
- RAM Disk supportability
Nano Server Management
The big news in
regards to Nano Server is on the management front. Clearly, as a completely
headless version of Windows Server, all management of Nano Server is
accomplished remotely. A variety of Microsoft management tools are available to
use, including MMC (Microsoft Management Console) Snap-Ins like Hyper-V Manager
or Services, Windows PowerShell, Desired State Configuration (DSC), Server
Manager, and Microsoft System Center. Microsoft also states that third party
management tools, such as Puppet and Chef, Nano will be supported.
Microsoft has
designed Nano Server to be fully manageable through automated means in keeping
with their cloud strategy, but fully realizes that some organizations will
prefer to perform some administration with GUI tools. It's important to
recognize the distinction between the headless nature of Nano Server and a
system that is only manageable through a command line. Nano Server does offer
support for management through GUI tools using remote management.

What's new in Hyper-V Private Cloud on Windows Server 2016
1. IN place Cluster upgrade
Finally, we can have in-place cluster upgrade feature, you can now add a node running Windows Server 2016 to a Hyper-V Cluster with nodes running Windows Server 2012 R2. The cluster continues to function at a Windows Server 2012 R2 feature level until you upgrade all of the nodes in the cluster and you upgrade the cluster functional level with the following Windows PowerShell cmdlet, Update-ClusterFunctionalLevel.
After you update the cluster functional level, you can't downgrade it back to Windows Server 2012 R2. Seems it’s going to work as Active Directory functional level.
When the Hyper-V Cluster has a mix of both Windows Server 2012 R2 and Windows Server 2016 nodes, you can still move virtual machines between all of the nodes in the Hyper-V Cluster.
After you upgrade the cluster functional level to Windows Server 2016, the following applies:
· To enable new virtual machine features, you need to manually upgrade the virtual machine configuration level of the virtual machines using the Update-VmConfigurationVersion cmdlet.
· You can enable new Hyper-V features.
· You can't add a node to the Hyper-V Cluster that runs Windows Server 2012 R2.
2. Nested virtualization
Yes, you can have this feature now. It will let you use a virtual machine as a Hyper-V host and create virtual machines within that virtualized host. This can be especially useful for development and test environments. To use nested virtualization, you'll need:
· At least 4 GB RAM available for the virtualized Hyper-V host.
· To run at least Windows Server 2016 or Windows 10 build 10565 on both the physical Hyper-V host and the virtualized host. Running the same build in both the physical and virtualized environments generally improves performance.
· A processor with Intel VT-x (nested virtualization is available only for Intel processors at this time).
3. Hot add and remove for network adapters and memory
Yes, finally this also available in VM G2 version, now you can add or remove a network adapter while the virtual machine is running, without incurring downtime. And its support Windows or Linux operating systems.
You can also adjust the amount of memory assigned to a virtual machine while it's running, even if you haven’t enabled Dynamic Memory. This works for both generation 1 and generation 2 virtual machines.
4. Networking features
New networking features include:
· Remote direct memory access (RDMA) and switch embedded teaming (SET). You can set up RDMA on network adapters bound to a Hyper-V virtual switch, regardless of whether SET is also used. SET provides a virtual switch with some of same capabilities as NIC teaming. For details, see Remote Direct Memory Access (RDMA) and Switch Embedded Teaming (SET).
· Virtual machine multi queues (VMMQ). Improves on VMQ throughput by allocating multiple hardware queues per virtual machine. The default queue becomes a set of queues for a virtual machine, and traffic is spread between the queues.
· Quality of service (QoS) for software-defined networks. Manages the default class of traffic through the virtual switch within the default class bandwidth.
5. Linux Secure Boot
Linux operating systems running on generation 2 virtual machines can now boot with the Secure Boot option enabled. Ubuntu 14.04 and later, SUSE Linux Enterprise Server 12 and later, Red Hat Enterprise Linux 7.0 and later, and CentOS 7.0.
6. Production checkpoints
Production checkpoints allow you to easily create “point in time” images of a virtual machine, which can be restored later on in a way that is completely supported for all production workloads.
7. Guest Integration services through Windows Update
Yes, you can have Guest Integration service updates through Windows Update.
8. Shielded Guest virtual machines
Shielded virtual machines use several features to make it harder for datacenter administrators and malware to inspect, tamper with, or steal data and the state of these virtual machines. Data and state is encrypted.
9. Windows PowerShell Direct
This will be easy and reliable way to run Windows PowerShell commands inside a virtual machine from the host operating system. There is no network, firewall requirements, or special configuration. It works regardless of your remote management configuration. To use it, you must run Windows 10 or Windows Server 2016 Technical Preview on the host and the virtual machine guest operating systems.
10. Windows Containers
Windows Containers allow many isolated applications to run on one computer system.

How/Why: Hyper-V Server failover cluster
Microsoft has long
offered a version of Hyper-V Server, but, for whatever reason, Hyper-V Server
has gained a reputation for only being appropriate for use in a lab environment.
Believe it or not, it is possible to deploy the Hyper-V Server in a way that
allows your Hyper-V virtual machines to be made highly available.
In order to build a
fault-tolerant Hyper-V deployment, there are a few things that you'll need.
First, you will need a storage
array that can be used for shared storage (CSV). These storage
requirements are the same as for any other Hyper-V deployment. Next, you need a
copy of Hyper-V Server, which can be found on the Microsoft website.
Third, you require a
basic understanding of how failover
clustering is normally deployed and configured. Having some up-front
knowledge of failover clustering will make it much easier to build a cluster
based on Hyper-V Server.
Finally, to build a
fault-tolerant Hyper-V
deployment, you must have a general knowledge of PowerShell.
If your PowerShell comprehension is a little rusty, I recommend taking
advantage of the Sconfig.cmd
utility. This utility provides a menu-driven interface for
configuring a server. Employing this utility will minimize the amount of
PowerShell that you will have to use.
The first step in
building a failover cluster using the Hyper-V Server is to install Hyper-V
Server on each server that will act as a cluster node. Once it has been
installed, you will need to use the Sconfig.cmd to establish the initial
configuration for each server. This means assigning an IP address to each network
interface card (NIC), giving each node a unique and meaningful computer name,
joining an Active Directory domain, and enabling remote management. All of
these tasks can be easily completed using the Sconfig.cmd utility.
Once you complete the
initial configuration process, you must make a few decisions regarding your
failover cluster. You will need to choose a name and an IP address
for the cluster. You will also need to figure out how you are going to connect
the cluster nodes to the shared storage. The easiest solution is to create two
Server Message Block file shares. One of these shares will be used as shared
storage, while another is used as a File Share
Witness.
For the sake of
demonstration, let's pretend that you wanted to create a cluster with a cluster
name of "Cluster1" and a cluster IP address of 192.168.0.1. Let's
also assume that the NIC that you want to use for cluster communications on
each cluster node is named "Ethernet 2" -- you can get the actual NIC
name by using the Get-NetAdapter cmdlet. Now imagine that your cluster nodes
are named "Hyper-V-1," "Hyper-V-2" and
"Hyper-V-3". Finally, we will need a Universal Naming Convention path
for our File Share Witness. We will also need to assign a name to the Hyper-V
virtual switch. For the sake of this demonstration, I will use
"Switch1" as the virtual switch name -- each node must use the same
virtual switch name -- and I will use "\\storage\witness" as the File
Share Witness path. Given those conventions, the commands used to build a
failover cluster would be:
Install-WindowsFeature
–Name Failover-Clustering –IncludeManagementTools
New-VMSwitch "Switch1" –NetAdapterName "Ethernet 2" –AllowManagementOS:$True
Test-Cluster –Node Hyper-V-1,Hyper-V-2,Hyper-V-3
New-Cluster –Name Cluster1 –Node Hyper-V-1,Hyper-V-2,Hyper-V-3 –StaticAddress 192.168.0.1
Set-ClusterQuorum –Cluster Cluster1 –NodeAndFileShareMajority \\Storage\Witness
New-VMSwitch "Switch1" –NetAdapterName "Ethernet 2" –AllowManagementOS:$True
Test-Cluster –Node Hyper-V-1,Hyper-V-2,Hyper-V-3
New-Cluster –Name Cluster1 –Node Hyper-V-1,Hyper-V-2,Hyper-V-3 –StaticAddress 192.168.0.1
Set-ClusterQuorum –Cluster Cluster1 –NodeAndFileShareMajority \\Storage\Witness
The only thing left to do
at this point is to connect your shared storage to the cluster. The method that
you will use to do so will vary depending on the type of storage that you are
using. You can use the Add-ClusterDisk cmdlet to get the job done, but I advise
installing the Failover Cluster Manager onto another Windows Server, one that
has a graphical user interface, and use that tool to add storage to the
cluster. That way you won't have to worry about the complexities of configuring
shared storage from the command line.
As you can see, it is
possible to achieve high
availability using the Hyper-V Server. That being the case, you may
be wondering why any organization would pay for a Windows Server license for
their Hyper-V nodes. The answer usually comes down to VM licensing. Windows Server
2012 R2 Datacenter Edition for instance allows a properly licensed Hyper-V host to run an unlimited number of
Windows Server 2012 R2 VMs. Without such a license, VM licensing must be
handled separately, which can be costly and complicated.
