AWS Simple Storage Service (S3)学习笔记

Amazon S3 provides developers and IT teams with secure, durable, and highly-scalable cloud storage.

Common use cases for Amazon S3 storage include:
Backup and archive for on-premises or cloud data
Content, media, and software storage and distribution
Big data analytics
Static website hosting
Cloud-native mobile and Internet application hosting
Disaster recovery

Each Amazon S3 object contains both data and metadata.
Objects reside in containers called buckets,and each object is identified by a unique user-specified key (filename). Buckets are a simple flat folder with no file system hierarchy.

data in an Amazon S3 bucket is stored in that region unless you explicitly copy it to another bucket located in a different region.

Each object consists of data (the file itself) and metadata (data about the file).
Objects can range in size from 0 bytes up to 5TB
This means that Amazon S3 can store a virtually unlimited amount of data.
The metadata associated with an Amazon S3 object is a set of name/value pairs that describe the object.
Every object stored in an S3 bucket is identified by a unique identifier called a key.
The combination of bucket, key, and optional version ID uniquely identifies an
Amazon S3 object.

Amazon S3 is storage for the Internet, and every Amazon S3 object can be addressed by a unique URL formed using the web
