Jeff Barr, Amazon Web Services evangelist, explains their new service – : “You can now break your larger objects into chunks and upload a number of chunks in parallel. If the upload of a chunk fails, you can simply restart it. You’ll be able to improve your overall upload speed by taking advantage of parallelism. In situations where your application is receiving (or generating) a stream of data of indeterminate length, you can initiate the upload before you have all of the data.”
Amazon S3 presents the data as a single object when all parts of the object get uploaded. Also, if transmission of any part fails, users can re-transmit that part without affecting other parts.
