Azure Blob - An Overview

Azure Blob storage is Microsoft's object storage solution for the cloud. Blob storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that doesn't adhere to a particular data model or definition, such as text or binary data.

Prerequisites for Creating an Azure Storage account

If you don't have an Azure subscription, you can create a free account before you begin.For more details refer the following link.

https://docs.microsoft.com/en-us/azure/storage/common/storage-account-create?tabs=azure-portal

After signing into the portal, create a storage account.
A storage account provides a unique namespace in Azure for your data. Every object that you store in Azure Storage has an address that includes your unique account name as seen in the following example:

http://mystorageaccount.blob.core.windows.net

Guidelines for creating a Container

 A container organizes a set of blobs, similar to a directory in a file system. A storage account can include an unlimited number of containers, and a container can store an unlimited number of blobs.

Before you can upload a blob, you must first create a container.

Naming conventions

A container name must be a valid DNS name, as it forms part of the unique URI used to address the container or its blobs. Follow these rules when naming a container:

  • Container names can be between 3 and 63 characters long.
  • Container names must start with a letter or number, and can contain only lowercase letters, numbers, and the dash (-) character.
  • Two or more consecutive dash characters aren't permitted in container names.

Guidelines  For Generating Access Keys

When you create a storage account, Azure generates two 512-bit storage account access keys. These keys can be used to authorize access to data in your storage account via Shared Key authorization.

Two access keys are assigned so that you can rotate your keys.

Note:  The account name, Container name and key are essential for  using the activities in the Azure Blob Automation package. Ensure not to share the keys with anyone.
