Application Research on Container Technology in DRaaS

The application scope of container technology has gradually expanded in cloud computing in recent years, because container technology is more lightweight and agile than virtualization technology. Based on the analysis of backup for disaster recovery preparedness and cloud computing service level, this paper summarizes the concept of disaster recover as a service, then principle and key technology of container are analyzed. Finally, the container thinking and DRaaS concept are combined, and DRaaS cloud service platform architecture based on container technology is proposed, also the advantages and service modes of this architecture are analyzed.
