Multi-site disaster recovery mechanism for distributed cloud orchestration software

摘要

Multi-site disaster recovery mechanism performed by the following steps: (i) providing a disaster recovery (DR) system that includes a plurality of sites where each site of the plurality of sites actively serves infrastructure-as-a-service to a set of tenant(s); (ii) for each site of the plurality of sites, determining the following characteristics of the site: workloads that require DR, workloads characteristics, tenants and capabilities; (iii) for each site of the plurality of sites, determining a plurality of associated sites; and (iv) on condition that a disaster occurs which impacts a first site of the plurality of sites, distributing a primary site workload of the first site across the associated sites of the first site. The determination of the plurality of associated sites associated with each site is based upon at least one of the following characteristics: capacity, workloads that require DR, workloads characteristics, tenants and/or capabilities.

1. A method comprising:
providing a disaster recovery (DR) system that includes a plurality of sites where each site of the plurality of sites actively serves infrastructure-as-a-service to a set of tenant(s), and all workloads associated with each tenant, respectively, are collocated on a single site; for each site of the plurality of sites, determining characteristics of the site: workloads that require DR, workload characteristics, tenants, and capabilities; for each site of the plurality of sites, determining a plurality of associated sites and sharing site metadata and site pairing information with the plurality of associated sites for at least one of automated disaster recovery via an external DR orchestrator and a manual disaster recovery process; and on a condition that a disaster occurs which impacts a first site of the plurality of sites, distributing a primary site workload of the first site across the associated sites of the first site; wherein: the determination of the plurality of associated sites associated with each site is based upon at least one of: capacity, workloads that require DR, workload characteristics, tenants, and capabilities.
