9. CloudStack & Private Cloud
CloudStack is also a choice for private cloud
• Maturity
• Stability
• Relatively easy to maintain
• Rich network features
• Freely customization
• Apache community

10. Private cloud customer focus
 Stability
 Customization
 Local support
 The fancy concept
 Cost

11. What they asked most?
• Virtualization & Cloud
• CloudStack vs. VMware
• CloudStack vs. OpenStack

12. Virtualization & Cloud
• Virtualization technology
• Software on top of OSes
• Infrastructure aware
• Relative small scale
• Maintenance on your own
• Expensive hardware
• Scale up for Performance tuning
• IT admin oriented
Server Virtualization Cloud(IaaS)
• Virtualization is fundamental
• Computing/Storage/Network
• Massive scale, easy operation
• Easy on administration
• Employee self-service
• Commodity hardware

• They got in trouble on OpenStack
• They don’t have extra resources on IaaS
• It’s easy to start with CloudStack
• CloudStack works fine
• They trust Apache community

17. Real case study
• Basic info
• Vision
• E-Gov whole picture
