It is also used for backup and recovery purpose. These objects can be accessed from any part of the world through http or https url.

It offers three types of resources which are storage account(account of users), container(folder for objects) and blob(stored files).

(ii) Azure Files- Azure files is used for storing the files which are highly shareable, i.e that are needed to be accessed by general public(i.e for public purpose).
