Blobs Storage• Storage Account
• An account can have many Containers
• Container• A container is a set of blobs
• Sharing policies are set at the container level • Public READ or Private
• Associate Metadata with Container• Metadata is
<name, value> pairs
• Up to 8KB per container
• List the blobs in a container

Table StorageTable
A storage account can create many tables
Table name is scoped by account
Data is stored in tablesA table is a set of entities (rows)
An entity is a set of properties (columns)
EntityTwo “key” properties that together
are the unique ID of the entity in the
tablePartitionKey – enables scalability
RowKey – uniquely identifies the
entity within the partition

A Queue contains messagesNo limit on number of messages stored in a queue
A message is stored for at most a week in a queue
http://<Account>.queue.core.windows.net/<QueueName>
MessagesMessage size <= 8 KB
To store larger data, store data in blob/entity storage, and the blob/entity name in the message
