Scalable - You will run out of money before disk. Exposed 15 cents per gigabyte to store. RESTful Web Services - Use Azure or local apps. Asian data centres are more expensive for data. . Can CDN Enable Account Account is secured with a 512 bit shared secret key. 500 TB per account. Storage in the Development Fabric - good for developing offline. - costs minimal (cents) if developing with less than 1 GB of data a month.Storage Security
- HTTPS - Digitally sign requests for privileged operations.Azure Storage Abstractions
Blobs - Could be used to serve static content. 60 MB/s output speed. Account Container - Grouping of blobs. Limited throughput per container. Blob - Identified by name Pages / Blocks - two types of blob. Blob is always accessed by name. Special $root container. - Allows for definition of clientaccesspolicy.xml http://[account].blob.core.windows.net/[containter]/[blobname] Can use prefix/delimiter and special blob naming to simulate directory structure. Pagination - returns continuation token (MarkerValue) to continue beyond page. Use Affinity group to keep computing and storage together and avoid paying for extra network traffic. Block Blob - used for streaming an entire file. ETags - versioning support over HTML Block blobs - can be uploaded in parallel via blocks and then recombined in Windows Azure Storage. Makes retry more efficient. Page Blob - targeted at random read/write workloads. Fixed 512 bytes Shared Access Signatures - E.g. Grant read access to a certain blob for a period of time and then pass to client as a URL. Revoke by timeout or via a container level policy that can be deleted. Ad Hoc Signatures. Policy Based Signature - container level policy allows revoking. Drives - Wrap the blob storage and allow NTFS volumes Tables - Queues -
Content Delivery Network (CDN)
Public blobs can be served via the Windows Azure CDN URL. Could map custom domain to the CDN.
