Linux on Windows Azure Andreas Wasita

Today’s Session Supported Linux Distributions. Setting up and accessing a new Linux VM. Securing your access to the VM. Managing Windows Azure (any service) from a Linux shell. Other Linux options on Azure (VMDepot).

Supported Distributions SUSE and Open SUSE: http://www.suse.com/suse-linux-enterprise-server-on-azure Canonical Ubuntu: http://www.ubuntu.com/cloud/azure OpenLogic CentOS: http://www.openlogic.com/azure Subject to Azure SLA and Azure support can manage break/fix tickets. Vendors above will work to rectify OS-level challenges. http://support.microsoft.com/kb/2805216

Demo: Create Linux VM We’ll create our first VM from Windows using PowerShell. Set-AzureSubscription -SubscriptionName "free trial" -CurrentStorageAccount kloudblob $Images = Get-AzureVMImage | Where-Object { $_.PublisherName -eq 'OpenLogic'} $affinityGroup = 'kloudnet' $vxName = Read-Host -Prompt 'Enter virtual machine name' $lxUser = Read-Host -Prompt 'Enter Admin UserName' $password = Read-Host -Prompt 'Enter Password' –AsSecureString New-AzureQuickVM -Linux -ServiceName $vxName -Name $vxName -ImageName $Images[0].ImageName -AffinityGroup $affinityGroup -InstanceSize Small -LinuxUser $lxUser -Password $password

Azure Access Control - PowerShell $acl = New-AzureAclConfig Set-AzureAclConfig -AddRule Permit -RemoteSubnet "10.0.0.0/26" -Order 1 ` -ACL $acl -Description "Lock down SSH" Get-AzureVM -ServiceName $vxName -Name $vxName | Set-AzureEndpoint -Name ssh -Protocol tcp -PublicPort 22 ` -LocalPort 22 -ACL $acl | Update-AzureVM

Securing access to a Linux VM Certificate-based security with SSH (hint: use openssl). Set an appropriate ACL on the Azure Cloud Service. Use a non-standard SSH port on your Cloud Service Endpoint. Use a bastion (or jump) host. Does this VM need to be publicly visible?

Management Cross-platform command line (node.js commandline). https://www.windowsazure.com/en-us/manage/linux/other-resources/command-line-tools/ PowerShell. Azure Management Portal.
