A Solution for A Disaster Recovery Service System in Multi-cloud Environment

The current enterprise information architecture is becoming more complex. As a result, user business data is lost or destroyed, services are interrupted, and systems crash, all of which harm users’ businesses. These factors include equipment failure, network attacks, and human error. Data disaster recovery has become an important method to ensure the sustainability of enterprise business. It is an inevitable trend toward disaster recovery services and technologies that “business in the cloud, cloud disaster recovery, and multi-cloud disaster recovery.” Traditional disaster recovery services systems and single-cloud disaster recovery services systems are unsatisfied with users’ current demands for business system deployment in multi-cloud environments, cloud resource sharing, and cross-cloud disaster recovery. We discuss the structure, composition, and functional ideas of a solution for a disaster recovery service system in multi-cloud environments. To provide cross-cloud disaster recovery management service in a multi-cloud environment with full-stack virtualization in response to user business requirements, it combines conventional disaster recovery technology, blockchain distributed multi-copy data storage and security audit, and system security state awareness.

At the moment, cloud disaster recovery is gradually supplanting traditional data disaster recovery. Government agencies, businesses, and institutions are increasingly choosing to use virtualization technology to create cloud data backup, business sustainability assurance, and disaster recovery services through cloud disaster recovery services offered by cloud service providers.
