Amazon Web Services 新的儲存方案:Amazon Glacier

Amazon Simple Storage Service (Amazon S3)AWS 第一代儲存服務。後來 S3 又提供了 Reduced Redundancy Storage,降低可靠度 (一年 99.99%) 換取價錢上的優勢,用在 cache file 之類的還蠻不錯。目前兩者在美東的價錢是 USD$0.125/GB 與 USD$0.093/GB。這兩種都是隨時可以存取的服務。

Amazon Glacier 則是提供超低的價錢與超高的可靠度:USD$0.01/GB 與一年 99.999999999%,而這是靠取回檔案的時間換來的。取回檔案需要排 3.5 到 4.5 小時的時間 (後面傳輸的時間另外計算):

Retrieving archives from Amazon Glacier requires the initiation of a job. Jobs typically complete in 3.5 to 4.5 hours.

是靠著機械手臂與軌道在處理嗎?

但這樣就多了很多用途啊... Data warehouse 是個很明顯的方向。目前可以透過 AWS Import/Export 匯入大量資料:

You can also use AWS Import/Export to accelerate moving large amounts of data into Amazon Glacier using portable storage devices for transport.

之後則是會提供從 S3 搬出去與搬進去的功能:

In the coming months, Amazon Simple Storage Service (Amazon S3) plans to introduce an option that will allow you to seamlessly move data between Amazon S3 and Amazon Glacier using data lifecycle policies.

等工具完整後再來研究 :p

    Amazon 該不會用了類似 Hitachi 曾經實驗用石英玻璃儲存資料的方式儲存資料?如果只單純求穩定,不考慮排除存取效能;用硬碟、晶片以外的材料作為儲存媒介,似乎也不錯..
