What it is: A feature that speeds up transfers between clients on the internet and a single S3 bucket by using CloudFront edge locations and the AWS global network. :contentReference[oaicite:2]{index=2}

What it’s for:

• Faster uploads/downloads over long distances (e.g., global users uploading large files). :contentReference[oaicite:3]{index=3}

Key ideas:

• Uses the `s3-accelerate` endpoint (e.g., `bucket-name.s3-accelerate.amazonaws.com`). :contentReference[oaicite:4]{index=4}
• Pricing depends on edge location; it’s “extra” compared to normal data transfer. :contentReference[oaicite:5]{index=5}

Exam cue (super important):

• If AWS determines S3TA is not likely faster than normal S3 transfer, AWS won’t charge S3TA for that transfer (and may bypass acceleration). :contentReference[oaicite:6]{index=6}

Hard words (English + IPA + Vietnamese meaning):

• *acceleration* /əkˌseləˈreɪʃn/: tăng tốc
• *edge location* /edʒ loʊˈkeɪʃn/: điểm biên (edge) của mạng
• *bypass* /ˈbaɪpæs/: bỏ qua
