Cloud-based Architecture Design of Conventional Applications

A small or micro enterprise intends to use Huawei Cloud Elastic Cloud Server (ECS) to deploy a small web-based forum for technical and experience sharing and enterprise promotion. The enterprise wants data to be stored separately from ECSs and to support independent access. Which of the following storage services are recommended as cost-effective options?

Choose two
Explanation

Object Storage Service (OBS) and Scalable File Service (SFS) are both storage services that exist independently of any ECS instance and can be accessed directly — via HTTP/HTTPS API for OBS, or as a shared network file system for SFS — by multiple clients without requiring the data to reside on an ECS's own attached volume, making them cost-effective choices for a small forum website that needs uploaded files and static content kept separate from the compute instance. Elastic Volume Service (EVS) is block storage that must be attached to a specific ECS and therefore is not independently accessible apart from that instance, and Dedicated Distributed Storage Service (DSS) provisions dedicated, exclusive storage resource pools intended for large enterprises with strict performance and isolation requirements, making it a costly option unsuitable for a small or micro enterprise.
