云存储不经常访问的文件？

Question

I'm creating an app for hosting files and photos. Files that have been uploaded recently will be accessed numerous times, so something like Amazon S3 would be excellent for this.

But as files grow older I expect them to be accessed very infrequently. However , when they are accessed, I still would like them to be available immediately, so Amazon Glacier doesn't work in this regard because restoration takes hours and hours.

Is there a storage solution somewhere in between the cost of S3 and Glacier where the price gets reduced dramatically because the files are accessed, say, once a year versus numerous times an hour, while still preserving instant access?

Answer 1

Azure提供[热和冷存储层] [1] [1]： https : //azure.microsoft.com/en-gb/documentation/articles/storage-blob-storage-tiers/用于blob存储，即冷层提供与热层相同的访问时间，同时提供不同的成本模型。

Answer 2

S3 has an infrequent access storage class, priced at a bit under half the cost of normal storage.

The tradeoffs you make are that objects under 128k are billed as if they are 128k and the availability target is 99.9% rather than 99.99%
