Method and device for realizing S3 standard object storage interface

Aspects of the invention relate to the field of data storage. The invention provides a method and a device for realizing an S3 standard object storage interface. In order to solve the problem of low file storage or reading efficiency of an implementation scheme that an object storage system utilizes a portable operating system interface, the method for realizing the S3 standard object storage interface comprises the following steps: receiving a user side interface calling request, and calling an interface provided by the object storage system by the user side; uploading the user side interfacecalling request to an ordered key value pair storage engine; and calling an interface of the ordered key value pair storage engine based on the user side interface calling request, and realizing theuser side interface calling request through the interface of the ordered key value pair storage engine. When the user side needs to store or read data, an interface of the object storage system is called, the object storage sy
