一些規則,規定誰可以做些什麼事情。
如何驗證你是誰
bucket name: johnsmith key: photos/puppy.jpg will produce s3 url: http://johnsmith.s3.amazonaws.com/photos/puppy.jpg
eventually consistency 某些未先查過的 put new object 是 read-after-write consistency
atomic (讀取非新即舊,不停止服務)
do not support object locking (幾乎同時寫的話,後寫者勝)
eventually consistency 有更大的彈性,例如 latency 可能增加,因為不用再去檢查其他 replica 是否是最新的了。throughput 也可能增加,但我不知道為什麼,文件寫的。
