Connect Azure Cloud Shell to Virtual Network vNet

Posted in Cloud, Containers, Microsoft, Microsoft Azure, PowerShell

As you know, Azure Cloud Shell is a great management tool to manage your Azure resources. Azure Cloud Shell is an interactive, authenticated, browser-accessible shell for managing Azure resources. It provides the flexibility of choosing the shell experience that best suits the way you work, either Bash or PowerShell. You can learn more about Azure Cloud Shell here. If you wanted to manage Azure resources such as Azure virtual machines (VMs), you needed to connect to a public IP address of a virtual machine, which really didn’t work in all scenarios. With the latest update, you can now connect Azure Cloud Shell to an Azure virtual network (vNet). With the new method, you can now deploy the Azure Cloud Shell container within your virtual network (vNet), which now allows you to use PowerShell remoting, SSH, or other command-line tools such as kubctl using private IP addresses.

Requirements

Before you can use Cloud Shell in your own Azure Virtual Network, you will need to create some resources to support this functionality.

Virtual Network – The virtual network in which the resources are located you want to manage or the network that peers with a virtual network where your Azure resources are.
Subnet – In that virtual network you will need a dedicated subnet to host Cloud Shell containers.
Network profile
Azure Relay – An Azure Relay allows two endpoints that are not directly reachable to communicate.
Storage Account – The storage account needs to be accessible from the virtual network that is used by Cloud Shell.

There are also some considerations you need to be aware of, such as currently supported Azure regions during the preview, Azure Relay adds additional cost and slower startup speed of Cloud Shell containers. You can learn more about the requirements here.

Connect Azure Cloud Shell to a virtual network

To make the deployment easy, there are Azure Resource Manager templates available to deploy the necessary network and storage resources. In my step by step guide, I already have a virtual network deployed within my subscription with the resources I manage. If you don’t have that yet, and you want to try this out, you will need to create a resource group and a virtual network.

Simply the deploy the following two templates:

Deploy Azure Cloud Shell Network ARM template

You can get the Azure Container Instance OID by running the following command:

Get-AzADServicePrincipal -DisplayNameBeginsWith 'Azure Container Instance'

Also, make sure that the subnet ranges are part of the address range in your virtual network.

Reconnect Cloud Shell

If you have used Azure Cloud Shell before, you will need to reconnect that to the specific resources. You can simply run the command “cloudrive unmount” or “dismount-cloudrive”.

After that you can reconnect your Cloud Shell and select the isolated network option. Keep in mind this feature is currently in preview, and only available in West US and West Central US.

Connect Azure Cloud Shell to virtual network

This will then take a moment to deploy.

Requesting a container

After the Cloud Shell container is deployed within the virtual network, you can now start using private IP addresses within that virtual network or virtual networks that are peered.

SSH into Azure VM with Private IP address from Cloud Shell

I hope this blog gives you a short overview of how you can integrate Cloud Shell in your private Azure virtual network. If you have any questions, feel free to leave a comment.

Automate your Cisco UCS with System Center Orchestrator

Posted in Cisco, Cloud, Hardware, Hyper-V, Microsoft, PowerShell, Private Cloud, Server, System Center, UCS, Virtual Machine Manager, Virtualization, Windows Server, Windows Server 2012, Windows Server 2012 R2, Work

Some days ago I posted an article how you can manage your Cisco UCS Blade Center directly from System Center Virtual machine Manager. Cisco also offers an Integration Pack for System Center Orchestrator which allows you to automate your Cisco UCS via Orchestrator Integration Packs, which is great if you are building your own Private Cloud based on Cisco hardware.

First step you have to download the Cisco UCS PowerTool (PowerShell Module) and the Cisco UCS Microsoft System Center Orchestrator Integration Pack.

After you have installed the Cisco UCS PowerTool on your System Center Orchestrator Runbook servers you now an import the Integration Pack via the System Center Orchestrator Deployment Manager. With a right click on Integration Packs you can Register the Cisco UCS IP.

After that you also have to deploy the IP to the Orchestrator Runbook servers.

You can start to create new Orchestrator Run Books with the Runbook Designer. First open the SCO Runbook Designer and in the Options menu select Cisco UCS to added the Path to the Cisco UCS PowerTool module (PowerShell module). The default path the Cisco UCS PowerTools are installed is: “C:\Program Files (x86)\Cisco\Cisco UCS PowerTool\Modules\CiscoUcsPS\CiscoUcsPS.psd1”

You can now start to automate your Cisco UCS with System Center Orchestrator.

If you are interested in how you monitor your Cisco UCS system with System Center Operations Manager Stefan Roth blogged about that.

Hyper-V Converged Fabric with System Center 2012 SP1 – Virtual Machine Manager

Posted in Hyper-V, Microsoft, PowerShell, Private Cloud, Server Core, System Center, Virtual Machine Manager, Virtualization, Web, Windows, Windows Server, Windows Server 2012, Work

This blog post is a part of a series of blog posts about System Center 2012 Virtual Machine Manager, I am writing together with Michel Luescher (Consultant from Microsoft Switzerland).

Hyper-V Converged Fabric

Last year I already wrote a blog post about Windows Server 2012 Hyper-V Converged Fabric or Converged Networking. Hyper-V Converged Fabric in a simple way allows you to use network adapters for different type of traffic. In Windows Server 2008 R2 Hyper-V we didn’t really had this capabilities because the network teaming relied on 3rd party software and Hyper-V itself didn’t offered a mature QoS solution. In other words, we had to go with what I now would call a traditional Hyper-V host design.

Traditional Design

Each dedicated Hyper-V network such as CSV communication or the Live Migration network used an own dedicated physical network interface. These different network interfaces could also be teamed with third party software, example with the software from HP, Broadcom or Intel. This design is still a good design in Windows Server 2012 but there are other configurations which are a lot more flexible.

In Windows Server 2012 you can get much more out of your network configuration. First of all NIC Teaming is now integrated and therefor out-of-the-box supported in Windows Server 2012. Another cool feature is the use of virtual network adapters in the Management OS (a.k.a. Parent Partition). This allows you to create a Hyper-V Hosts with all the necessary networks (Management, Live Migration, Cluster,…) by teaming just two or more physical adapters for a virtual switch and then create the additional virtual network adapters (vNICs) for the Hyper-V Management OS.
