Azure Blob Uploader

The Azure Blob Uploader application was designed to be a tool for uploading large size blobs, as blocks of data to the Windows Azure Blob storage. If the upload fails in the middle, the tool should resume the upload from where it failed (rather than starting over).

The file to be uploaded is broken down into individual blocks. Each block has a specified size (as specified by the user), and is specified by a unique ID. Each block is scoped by a blob name (which is same as the file name). The upload process uploads each block individually and maintains the information of the current uploading position (specified by the stream position in bytes) in an XML file (uploadmetadata.xml created in the directory from which the tool executable was invoked).

The tool required the following input from the user: - Account Name: Windows Storage account name - Account Key: Windows Storage account key - URI: Endpoint URI of the BLOB storage service - Container Name: BOB Storage container, where the blob needs to be uploaded to. The tool creates the container if it does not exists - Input File: The name of the file to be uploaded. - Block Size: The size of each individual block
