This paper addresses the increasingly prominent issues of data compliance in cloud computing environments

taking the perspective of cloud service providers to delve deeply into the rational allocation and effective implementation mechanisms of data compliance responsibilities. It begins by examining and synthesizing domestic and international relevant laws and regulations

thereby clarifying the legal responsibility boundaries for cloud service providers during the processes of data processing

storage

transmission

and protection. Subsequently

the article constructs a comprehensive data compliance responsibility allocation model tailored for cloud services

considering the roles and obligations of cloud service providers

cloud clients

and third-party service providers. Finally

the research proposes a multi-faceted fulfillment mechanism encompassing policy formulation

application of technical means

internal management improvements

and enhanced external collaboration. The aim is to provide theoretical guidance and reference for cloud service providers to establish and improve their data compliance management systems through this study.
