What is Disaster Recovery?

According to Wikipedia, Disaster Recovery (DR) is "the process, policies and procedures . . . for recovery . . . of technology infrastructure . . . after a natural or human-induced disaster.”

Project Goals and Milestones

❑ Goal: Disaster Recovery for OpenStack Clouds

❑ Phase 1: Using backup and restore ❑ ships with IBM Cloud manager With Openstack

•  Support for disaster recovery via backup and restore

❑  Included in European FP7 ORBIT Research project •  Disaster recovery to a remote site – 260km •  http://www.orbitproject.eu/

❑ Phase 2: Using real time replication for zero downtime recovery ❑  Proof of Concept

Cloud to Cloud •  Off-premises services & storage •  Storage replication between two

cloud locations

Physical to Cloud •  On-premises service & storage •  Storage replication / extension into

cloud

• Spectrum Accelerate provides replication between on-premises and cloud

Use case: Bursting to the Cloud with Spectrum Accelerate

• Spectrum Accelerate provides replication between on-premises and cloud •  Move application 2 to run on the cloud – the data is already there

•  We now freed both storage resources (IOPS) and compute resources on our on-premises

Project Highlights

•  Create disaster recovery enablement in OpenStack •  Protect selected application(s) and their data

•  instances, volumes, networks, SSH keys, etc. •  Recover in an alternative cloud upon disaster

•  Architecture •  Built as an OpenStack project •  Utilize existing OpenStack projects

•  Heat for orchestration •  Swift as 3rd party object storage

•  Pluggable architecture

•  API •  Protect, failover, failback
