2. Cloud Storage
• Consumer oriented cloud storage services – mainly
from consumer product vendors
• Cloud infrastructure / platform oriented storage
services – mainly from cloud service vendors

3. Cloud Storage in Azure
Azure Storage
Blob Table Queue File Storage (preview)

4. Azure Blob Storage
Blob
Block Blobs
(streaming binary objects)
Page Blobs
(disks used in Azure VMs)

5. Azure Blob Storage – Demo
Containers
Monitoring
Alerts
Logs
Tools (Storage Explorer)
Azure SDK Sample
Import/Export

6. Azure Blob Redundancy
• LRS – Local Redundant Storage – 3 copies in single DC
• ZRS - Zone Redundant Storage – 3 copies in different DCs in same region
or different regions.
• GRS – Geo Redundant Storage – 6 copies. 3 in LRS mode and 3 in DCs in
different geo regions.
• RA GRS – Read Access Geo Redundant Storage – 6 copies same as GRS
but the 3 copies in different geo DC also have read access.

7. Cloud Storage in AWS
AWS Storage
S3 Glacier

8. AWS S3 – Demo
Buckets

9. S3 Redundancy
• Standard – Replication among DCs in the same region
• Reduced Redundancy Storage – Replication within single DC
• Cross Region Replication – Replication with DCs in a different selected
region
