Azure Blob Storage

Azure Blob Storage is Microsoft’s object storage service, part of the Microsoft Azure cloud platform. It stores vast amounts of unstructured data — files, images, video, backups, logs, and training datasets and model weights for machine learning. It offers access tiers (hot, cool, cold, archive) for cost optimization, high durability and availability, integration with Azure AI and analytics services, and security and access-control mechanisms. It is a foundational data-infrastructure component for AI workloads in the Azure ecosystem.
