クラウド管理者は、現在の CSR 内に新しいシステムを実装する必要があります。このシステムには、大量のデジタル ファイルと画像を割り当てるストレージ サービスが必要です。ストレージ サービスは、分散アクセス用にファイルを保持し、ユーザーのブラウザに画像を直接提供する必要があります。これらの要件を最もよく満たすソリューションは次のどれですか?
正解:B
Explanation
One possible solution for the cloud administrator is to use object storage. Object storage is a type of cloud storage service that stores data as objects, which consist of data, metadata, and a unique identifier. Object storage can allocate a large number of digital files and images, as it can scale to petabytes of capacity and handle billions of objects. Object storage can also keep files for distributed access, as it can store data across multiple regions and zones, and provide high availability and durability. Object storage can also serve images directly to the user's browser, as it can generate public URLs for each object that can be accessed over the internet12.
NAS storage, file storage, and block storage are not the best solutions for these requirements, as they have some limitations compared to object storage. NAS storage and file storage store data as files in a hierarchical structure, which can be inefficient for managing a large number of files and images. Block storage stores data as blocks in a fixed structure, which can be wasteful for storing variable-sized files and images. NAS storage, file storage, and block storage also require a file system or a protocol to access the data, which can add complexity and overhead to the system12.
