AWS storage service for multi-tenant web app

Question

哪些服务可方便地为每个租户创建特定数量的存储分配，增加/减少容量以及监视可用和已用容量。

Answer 1

The most flexible storage option on Amazon Web Services is S3 - Simple Storage Service.

S3 is an object store storage facility with which you can upload objects of any type. S3 also support multipart uploads for big files.

To separate your different tenants data, you could use folders in a bucket and do some application logic to stop different tenants accessing each others files.

You can use bucket policies to give different IAM users access to different folders, however, it wouldn't make sense to create an IAM user for each of your tenants.

I encourage you to read the docs:
