Challenge
• HA for VMs and Web applications or
services
• Requests burst during weekends and
holiday, promotion seasons
• 7x during weekends
• 30x during promotion seasons
Demo Scenario
• VM failure discovery and recovery
• Cross-region VM group scaling
1
Suning Cloud Based on IBM Technologies
OpenStack & IBM Together
• Nova to poll and notify host and VM
failure events
• Ceilometer to consolidate notifications
and signal to Heat
• Heat to orchestrate VM recovery and
auto-scaling (policy based)
Benefits
• Business continuity in case of physical
resource failures and overload
• Cost saving from on-demand resource
provisioning
