Storage accounts were put into place to help provide a filesystem style structure for data/blob object repositories in the cloud. Their pricing tiers cover physical storage and ingress/egress. These data objects are usually stored in the following fashion:
- Azure blobs are used for text and binary data
- Azure files are for file shares in the cloud
- Azure Queues are used for reliable messaging
- Azure tables are for the schema-less storage of structured data
There are currently two types storage media:
- Standard: Storage on magnetic storage devices
- Premium: Storage on SSD
All data is written to the stores with Storage Service Encryption (SSE) and can leverage RBAC from AAD to manage access.
You will need to manage CORS rules for your resource that access resources from other domains. CORS, or Cross-Origin Resource Sharing, is not an authentication mechanism but an access one from other domains.
They have three storage account options:
- General Purpose v2 (GPv2): Support all the latest features, and you can choose better hot and cold storage tiers
- General Purpose v2 (GPv1): For high churn or read rates
- Blob Storage: Supports all blob features
