About Azure Blob Storage
Azure Blob Storage is the object storage service in Microsoft Azure. It is meant for large amounts of unstructured data, including documents, images, backups, logs and analytics datasets, and it is described by Microsoft as scalable and cost-efficient for demanding workloads.
Blob Storage is commonly used as the foundation for backup and archive, content delivery origins and data lakes, and it integrates with other Azure services for analytics, machine learning and security monitoring. Customers access it through APIs, SDKs and tools from within the Azure portal and developer environments.
Azure Blob Storage is proprietary and available only as a cloud service within an Azure subscription, so there is no self-hosted version. Costs depend on the amount of data, the access tier and operations used, and are described on the Azure pricing pages.
