2. Windows Azure Storage Services Saranya Sriram, Technology Evangelist, Microsoft, India

4. Windows Azure Storage Storage in the Cloud  Scalable, durable, and available  Anywhere at anytime access  Only pay for what the service uses Exposed via RESTful Web Services  Use from Windows Azure Compute  Use from anywhere on the internet

5. Windows Azure Storage Account User specified globally unique account name US Europe Asia Can choose geo-location to host storage account:

6. Windows Azure Storage Account Can CDN Enable Account  Blobs delivered via 24 global CDN nodes Can co-locate storage account with compute account  Explicitly or using affinity groups Accounts have two independent 512 bit shared secret keys 100 TBs per account

7. New Features Geo-Replication Storage Analytics  Logs: Provide trace of executed requests for your storage accounts  Metrics: Provide summary of key capacity and request statistics for Blobs, Tables, and Queues Improved HTTP headers for Blobs

8. Storage in the Development Fabric Provides a local “Mock” storage Emulates storage in cloud Allows offline development Requires SQL Express 2005/2008 or above

9. The Storage Client API In this presentation we’ll cover the underlying RESTful API  Can call these from any HTTP client e.g. Flash, Silverlight, etc… Client API from SDK Microsoft.WindowsAzure.StorageClient  Provides a strongly typed wrapper around REST services

10. Storage Libraries in Many Languages

11. Storage Security Windows Azure Storage provides simple security for calls to storage service  HTTPS endpoint  Digitally sign requests for privileged operations Two 512bit symmetric keys per storage account  Can be regenerated independently More granular security via Shared Access Signatures

23. Higher durability 3 local replicas in primary location Local replicas – synchronously replicated Common failures (disk, node, rack) – use local copies to recover Major disasters – contact customer about potential data loss Reduced Price – 23-34% based on how much you store Turn off Geo for your storage account in portal Non-critical data that can be recreated on major disasters Application manages its own replica Companies have limitations on geo locations Locally Redundant Storage Highest level of durability 3 local replicas each in primary and secondary locations Local replicas – synchronously replicated Geo replica – asynchronously replicated Common failures (disk, node, rack) – use local copies to recover Major disasters – use geo replicated copy (400+ miles apart) Price remains the same as before Enabled by default Geo Redundant Storage
