Provision VM from Image or Disk using portal, script or API

Use Cases• Forklift Migration of VMs

• Sys Prepped Images

VHD Must Be Fixed Disk * CSUpload Can Convert on Upload

Application Migration

Migration Approaches

Build Virtual Machine in the CloudLowers upload time and dependency riskRequires upload and installation of application and data

Migrating an Existing Virtual MachineApplication, Configuration and Data in an installed Working State Requires uploading a large amount of data and a higher risk of drivers or other hardware dependencies on VM not available in the cloud

Migrating a Multi-VM ApplicationCloud Service Acts as a Networking BoundaryAll VMs in the same service can communicate directlyName resolution between VMs is automatic with Windows Azure provided DNSCloud Service

Windows Azure Supports VHD File FormatOther formats will have to be converted or migrated before upload

Upload Existing VHDs using CSUpload.exeSupports Resuming Failed Transfers Converting from Dynamic to Fixed Disk on UploadEfficient Upload – does not send empty bytes

Migration Steps1) Upload VHDs CSUpload or other Tools

2) Create VM OS Disk=APP-OS.vhd

3) Configure Data Disks Data Disk 1 = APP-Data.vhd Data Disk 2 = App-Logs.vhd

4) Adjust App for Drive Letters

5) Add Endpoint(s) 80, TCP, http 443, TCP, https

TCP Endpoints 80 and 443

Deploying Enterprise Applications

Windows Azure Virtual Network

Persistent IP Address RequirementsVirtual Machines deployed into a virtual network have an infinite DHCP lease.

Hybrid On-Premises Cloud AppsRequirement for connectivity between your data center and the public cloud.

Connectivity between cloud services. Deploying Active Directory in the Cloud or connecting a PaaS to IaaS Service.

Managing VMs

Managing Windows Azure VMs

Windows Azure Virtual Machines are not “different”Existing Monitoring and Management Applications will continue to work

Connectivity Will Be KeyUsing Windows Azure Virtual Networks to bridge the connectivity divideManagement Applications may have more streamlined solutions such as the System Center Gateway Service

For Azure Specific Automation Tasks Use PowerShell

Scripting CapabilitiesFull Support for IaaS• Windows Azure PowerShell Cmdlets• Cross Platform Scripting Built on node.js

Capabilities• Provisioning, Removal• Reboot, Start• Import and Export VM settings• Support for Windows and Linux VMs• Domain Join at Provision for Windows• Fully Customize VM with Data Disks

and Endpoint Configuration• Automate Virtual Network Settings
