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.”
Servers Storage Network Software Configuration
Surviving a disaster requires geographic dispersion

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

Use case: Spectrum Accelerate for the Cloud

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
