12 Blobs mechanism for storing named files and associated metadata Tables place for structured data, containers of entities Queues reliable storage and delivery of messages between service roles Drives durable NTFS volumes for Windows Azure services (coming soon)

13 Blobs are stored in Containers Also can be stored at root level Hierarchical naming Two kinds of blobs Block optimized for streaming Page optimized for random read/write access One or more Containers per account Blobs and Containers have associated Metadata Name/Value pairs (8KB total) CRUD, snapshot, copy, lease (lock) Custom domain names and CDN Private or public Container and Blob access Shared Access Signatures Granular permissions for Blobs and Containers Encoded in blob and container URLs

14 Table is a set of Entities (rows) Entity can be up to 1MB in size No limit on number of tables or entities Entity is a set Properties (columns) Supported types - bool, int32/64, double, string, DateTime, Guid, byte[] Maximum of 255 Properties per Entity PertitionKey, RowKey, and Timestamp are mandatory Tables are automatically partitioned based on PartitionKey values Load balancing Query efficiency vs. scalability No limit on number of partitions Entities are uniquely identified by PartitionKey + RowKey Both are strings under 1KB Determine entities sort order (lexicographical) Not a relational database No schema, constraints, relations, stored procedures, triggers, etc. Optimistic concurrency, high availability, automatic load management, in partition transactions

15 Queues contain Messages Message size is up to 8KB Can have associated metadata No limit on number of Queues or Messages Limit for Message expiration Provide reliable message delivery Retrieved and processed at least once Dequeue with timeout Dequeue multiple messages Polling model
