What is the primary purpose of a container in Azure?

The primary purpose of a container in Azure is to group blobs and organize them in a hierarchical structure. In Azure Blob Storage, containers serve as a way to logically organize and group related blobs, making it easier to manage storage and apply permissions. Each container can hold an unlimited number of blobs, which can be of various types, including block blobs, append blobs, and page blobs.

By using containers, users can effectively categorize and separate different types of data within the same storage account, simplifying data retrieval and management processes. This structure allows for better organization and potentially more straightforward security and access control configurations, as permissions can be applied at the container level.
