Amazon S3 provides API for multipart upload of large files. Multipart upload allows you to upload a large object as a set of small parts/portion of the object's data. You can upload these small object parts independently. If transmission of any part does not succeed, you can retransmit it without affecting other parts.
Finding the way to store ,distribute and manage the data are big challenge. We know that the building and maintaining our own storage repository is expensive and time consuming. Amazon Simple Storage Service (amazon-s3 is the better way) provides developers and IT teams with secure, durable, highly-scalable object storage
