S3 Multipart Upload

S3 Multipart Upload is an Amazon S3 API built for optimizing performance and upload success rate. In a nutshell, S3 Multipart Upload allows you to upload every single object as a collection of parts.

This is how it works:

1. The object you want to upload is split into smaller parts for efficient uploads.
2. The parts are uploaded independently, in parallel connections.
3. Once all the parts are successfully uploaded, the object is ready to be downloaded back again.

Note: Once a 'part' reaches the server, it goes through all the security steps that make Cubbit geo-distributed technology unique.
