Windows Azure Content Delivery Network (new)

bull Windows Azure Content Delivery Network (CDN) provides high-bandwidth global blob content deliverybull 18 locations globally (US Europe Asia Australia and South America) and growing
bull Blob service URL vs CDN URLndash Windows Azure Blob URL httpsallyblobcorewindowsnetndash Windows Azure CDN URL httpltguidgtvomsecndnet ndash Custom Domain Name for CDN httpeventscohowinerycom
Windows Azure XDrive (new)
bull Provides a durable NTFS volume for Windows Azure applications to usendash Use existing NTFS APIs to access a durable drive
bull Durability and survival of data on application failover
ndash Enables migrating existing NTFS applications to the cloud
bull A Windows Azure Drive is a Page Blobndash Example mount Page Blob as X
bull httpltaccountnamegtblobcorewindowsnetltcontainernamegtltblobnamegt
ndash All writes to drive are made durable to the Page Blobbull Drive made durable through standard Page Blob replicationbull Drive persists even when not mounted as a Page Blob
Windows Azure Drive Capabilities
bull A Windows Azure Drive is a Page Blob formatted as a NTFS single volume Virtual Hard Drive (VHD)ndash Drives can be up to 1TB
bull A VM can dynamically mount up to 8 drivesbull A Page Blob can only be mounted by one VM at a time for
readwrite
bull Remote Access via Page Blobndash Can upload the VHD to its Page Blob using the blob interface and
then mount it as a Drivendash Can download the Drive through the Page Blob interface
Windows Azure Drive Client Interface
bull Create Drivendash Create a Page Blob and format it as a NTFS single volume VHD

Windows Azure XDrive Summary
bull Provide Durable NTFS volumes via a VHDndash All NTFS non-buffered writes and flushescommits are made
durable to the Page Blob
bull Drives are NTFS formatted Page Blobsndash Can upload and download the drive via the Windows Azure Blob
interfacendash Can backup and share drives via Blob Snapshot and Copy
bull Drive mounting scenariosndash A Page Blob can only be mounted by one VM at a time for
readwrite accessndash Can mount a read-only snapshot with any number of VMs
Storage Durability
1 Replicate within the same geo-location ndash PDCrsquo08
2 Allow applications to choose geo-location ndash MIXrsquo09
3 Geo-replicate data across geo-locations ndash Commercial Availabilityndash Maintain multiple copies of your data in 2 geo-
locations within the same geo-region (US Europe Asia)
Geo-Replication
bull Still choose the Primary Geo-Location for your storage account via the Dev Portalndash This is where your data is served from
bull Updates to data are immediately replicated and committed at primary geo-locationndash No change in existing performance
bull Asynchronously geo-replicate data updates from primary to secondary geo-location
