--tips
You can configure buckets so that they are created in a specific Region.

eventual consistency
read-after-write consistency
--關於這兩個概念今天前面有一片博文有介紹

Amazon S3 does not keep copies or move it to any other region.
不跨區儲存，也不會自動的在資料中心間移動框和物件。

Two ways of controlling access to buckets and objects :
access control list (ACLs)
bucket prolicies
Policies are a collect of statements that define a user's permissions to access amazon S3 resouces .

S3目前不支援物件鎖，如果兩個put請求對一個物件操作，
則時間戳晚的生效，如果這樣有問題，需要在你自己的應用中構建物件鎖機制。

The following features are currently unavailable in the AWS Management Console:
Requester pays
BitTorrent
Versioning

PART ONE::::::::::Working with Buckets
====================================================================
S3與不同的網路儲存的區別在哪裡？

the storage class of the objects in the buckets

Note:You are not charged for creating a bucket,you are only charged for storing
objects in the bucket and or transfering objects in and out of the bucket.

Bucket names requirements:
Can contain lowercase letters,numbers,periods(.),underscores(_),and dashes(-)
Must start with a number or letter
Must be between 3 and 255 characters long
Must not be formatted as an IP address (e.g.,192.168.5.4)

request access log:
request type
the resources specified in the request worked
the time and date the request was processed
--
However,by default,S3 does not collect server access logs

Note
A check box enable you to configure your bucket as a website.
If you clear the Enabled check box,Amazon S3 removes any existing website configuration
from the bucket,and the bucket is not accesiable via the website endpoints.

PART TWO::::::::::::Working with Objects
====================================================================
Objects can be any file type:image_backup,data,movies,etc

There are two types of metadata:system and user.
S3 never process user metadata. User metadata is stored with the object and
returned with it.The maximum size for user metadata is 2KB,and both the keys and their
values must conform to US-ASCII standards.
