DKOS Situation
• Active cluster : 400
• Total compute node : 4000 (vm+pm)
• Container counts : 8800
• Managed by?
DKOS Situation
• Why use DKOS(container)?• Container easy• Container cool• dc/os is great
• Nop!• Very summit point of integrated/automated infra platform

Before tackling CloudS?
Abstractionshould come first
Fully abstracted operation

• Service catalog
• notification
• scheduling
