Windows Azure is Microsoft’s cloud platform that enables you to quickly build, deploy and manage applications and store your data across a global network of Microsoft managed datacentres.

Inactivity Period t On & off workloads (e. g. batch job) Over provisioned capacity is wasted Time to market can be cumbersome Growing Fast Compute t Successful services needs to grow/scale Keeping up w/ growth is big IT challenge Cannot provision hardware fast enough Unpredictable Bursting Compute t Unexpected/unplanned peak in demand Sudden spike impacts performance Can’t over provision for extreme cases Predictable Bursting Compute On and Off t Services with micro seasonality trends Peaks due to periodic increased demand IT complexity and wasted capacity

SAN Storage • i. SCSI SAN with auto-tiering (SSD/SAS) • Automated snapshots • Primary dedupe/compress With Cloud Data Management Seamless Cloud Integration for: • Tiered primary + archives • Cloud snapshots: mountable for DR On an Enterprise-Class Platform • Certified: VMware-ready and Microsoft Windows Server-certified • HA: full redundancy + hot swaps + non-disruptive upgrades • • • 17

Total data capacity required = 10 TB • • Maximizes storage of ‘hot or warm data’ on-premise for higher IOPS and/or lower response times for application access. Minimizes size of data transfer and storage in Azure Works at the block-level and replaces duplicate data blocks with a meta data map (pointers to the original block) Data is de-duped in the SSD tier and compressed in the SAS tier before being tiered to Azure • On-premise data capacity can be increased by 2 x – 5 x based on the type of data stored • Backup de-dupe: Cloud snapshots are differential and thereby eliminate copies of redundant blocks across backups Data blocks E F A A B B D A C A D C C B D C 5 x de-dupe ratio Data blocks Capacity used = 2 TB A B D E C F Metadata map + • De-duped • Compressed

Backup, Restore & DR Today: Inefficient, Complex, Laborious, and Risky Primary Volume Snapshot Virtual Tape/ Replication Physical Tape Offsite Tape Storage Backup, Restore & DR with Stor. Simple: Automated, Optimized, Reliable Snapshots Primary Volume Cloud Snapshots 1. Backup copy of data volume created in cloud 2. Changes to local volume automatically transferred 3. Cloud snapshots mountable for restore Benefits • Backup now as easy as snapshots • Very fast restores from off-site backups • Integrated, easy to test disaster recovery • Truly eliminates tape 23
