Understanding a Linux VM

Why Linux

Our customers have Linux Workloads that they want to run in Windows Azure

IaaS enables us to satisfy this need

Distributions

We will supportSUSE SLES 11 sp2Open SUSE 12.1CentOS 6.2 by OpenLogic* Ubuntu 12.04

Specific versions are endorsedIntegration ComponentsTesting and validation by partnersBring other variants at your own risk**

( at GA only)

*Image provided by OpenLogic based on CentOS 6.2**Integration Work will be needed

Some interesting Python, Bash and Powershell stuff

Simple VM Creation

First Virtual Machine in a NEW Cloud Service (-Location specified)New-AzureQuickVM -Windows -ServiceName $svc -Name $vm1 -ImageName $wimg -Location $location -Password $pwd

New Virtual Machine in an Existing Cloud Service (no –Location)New-AzureQuickVM -Windows -ServiceName $svc -Name $vm2 -ImageName $wimg -Password $pwd

Creating a Linux Virtual Machine in an Existing Cloud ServiceNew-AzureQuickVM -Linux -ServiceName $svc -Name $vm3 -ImageName $limg -LinuxUser $lu -Password $pwd

Configuring VM at Provisioning

Create Configuration Object with New-AzureVMConfigModify with Add-* cmdletsAdd with New-AzureVM

New-AzureVMConfig -Name $vm1 -InstanceSize Medium -ImageName $img | Add-AzureProvisioningConfig -Windows -Password $pwd | Add-AzureDataDisk -CreateNew -DiskLabel 'data' -DiskSizeInGB 10 -LUN 0 | Add-AzureEndpoint -Name 'web' -PublicPort 80 -LocalPort 80 -Protocol tcp | New-AzureVM -ServiceName $newSvc -Location $location

VM Batch Creation

Create Multiple Configured VMs and Pass to New-AzureVM

$vm1 = New-AzureVMConfig -Name 'myvm1' -InstanceSize 'Small' -ImageName $img | Add-AzureProvisioningConfig -Windows -Password $pwd

$vm2 = New-AzureVMConfig -Name 'myvm1' -InstanceSize 'Small' -ImageName $img | Add-AzureProvisioningConfig -Windows -Password $pwd $vm3 = New-AzureVMConfig -Name 'myvm1' -InstanceSize 'Small' -ImageName $img | Add-AzureProvisioningConfig -Windows -Password $pwd New-AzureVM -CreateService -ServiceName $cloudSvcName -VMs $vm1,$vm2,$vm3 -Location $dc

VM Batch Creation (using an array)

Create Multiple Configured VMs and Pass to New-AzureVM

$vmcount = 5$vms = @()for($i = 0; $i -lt 5; $i++){ $vmn = 'myvm' + $i $vms += New-AzureVMConfig -Name $vmn -InstanceSize 'Small' -ImageName $img | Add-AzureProvisioningConfig -Windows -Password $pwd | Add-AzureDataDisk -CreateNew -DiskLabel 'data' -DiskSizeInGB 10 -LUN 0 | Add-AzureDataDisk -CreateNew -DiskLabel 'logs' -DiskSizeInGB 10 -LUN 1 }
