Azure Blob Storage

Azure Blob Storage is Microsoft’s scalable object storage solution for the cloud, ideal for storing large amounts of unstructured data. In Blober, Azure paths use:

container-name/path/to/blob.ext
  • ✅ Browse containers and blobs
  • ✅ Upload files
  • ✅ Download files
  • ✅ Delete files
  • ✅ Copy between containers
  • ✅ Move blobs
  • ✅ Change blob tier (Hot/Cool/Cold/Archive)
  • An Azure account (create one free)
  • An Azure Storage account
  • Storage account access keys or connection string

  • Option key: connectionString
  • Format: A connection string containing account name, key, and endpoint

Example:

DefaultEndpointsProtocol=https;AccountName=myaccount;AccountKey=mykey;EndpointSuffix=core.windows.net

  • Option key: storageTier
  • Default: Cool
  • Values: Hot, Cool, Cold, Archive
