Performance Optimization

• Single PUT Upload:

  • Upload a single object all as one part.

  • If transmission fails, then you have to restart the whole upload.

• Multipart Upload:

  • Upload a single object as a set of parts.

  • Each part is a separate portion of the object's data.

  • If transmission of any part fails, you can retransmit that part without affecting other parts.

  • After all parts of your object are uploaded, Amazon S3 assembles these parts and creates the object.

  • When object size is above 100 MB, you should use multipart uploads instead.

  • Maximum object size = 5 TB

  • Maximum number of parts per upload = 10,000

• Transfer Acceleration:

  • Designed to optimize transfer speeds from across the world into S3 buckets.

  • Uses globally distributed edge locations.

  • As the data arrives at an edge location, data is routed to Amazon S3 over an optimized network path.

  • The name of the bucket used must be DNS-compliant and must not contain periods/dots.
