Azure Storage was the first service built among the Azure services. It is the fundamental building block of Azure. Following are the offerings of this service:
Scalability: It is easily scalable. You can start with a small-size blob and scale to an infinite size depending on the demand without affecting production.
Durability: Data in Azure storage is very durable with multiple levels of redundancy in which you have just to mention the type of redundancy and Azure does the rest of the work for you.
Availability: The replication option enables you to store copies of your data in different availability zones, and in the event of zone or node destruction, the data is still available.
