Introduction
Before
moving into Azure Data Factory (ADF), we need some general knowledge regarding
Azure storage. The ADF can Extract and Load data from Azure storage.
So, it is necessary to take little bit of knowledge about it.
Type of Azure Storage
There are two type of Azure Storage
ü Azure Standard Storage
ü Azure Premium Storage
Azure Standard Storage Account
Blog Storage
Blog Storage is basically storage for unstructured data that can include
pictures, videos, music files, documents, raw data, and log data…along with
their meta-data. Blobs are stored in a directory-like structure called a “container”. We can store any
number of blob files up to a total size of 500 TB and we can also apply
security policies.
Azure Table Storage
Table storage, as the name indicates, is preferred for tabular data,
which is ideal for key-value NoSQL data storage. Table Storage is massively scalable
and extremely easy to use.
Azure File Storage
Azure File Storage is meant for legacy applications. Azure VMs and
services share their data via mounted file shares, while on-premise
applications access the files using the File Service REST API. Azure File
Storage offers file shares in the cloud using the standard SMB protocol and
supports both SMB 3.0 and SMB 2.1.
Azure Queue Storage
The Queue Storage service is used to exchange messages between components
either in the cloud or on-premise (compare to Amazon’s SQS). We can store large
numbers of messages to be shared between independent components of applications
and communicated asynchronously via HTTP or HTTPS. Typical use cases of Queue
Storage include processing backlog messages or exchanging messages between
Azure Web roles and Worker roles.
Azure Premium Storage account
The Azure Premium Storage service is the most recent storage offering
from Microsoft, in which data are stored in Solid State Drives (SSDs) for
better IO and throughput. Premium storage only supports Page Blobs.
