and course
●Study easy! and help to take points!
– Requirement
●On the web
●Limited access
●Temporary
●Free or low cost

Cloud Service
■SaaS
■PaaS
■IaaS

Software as a Service
(SaaS)
Using application in Cloud
Ex) Google Apps

Platform as a Service
(PaaS)
Using Cloud environment to develop applications
Ex) CloudFoundry

Infrastructure as a Service
(IaaS)
Using infrastructure (server, network, storage) in Cloud
Ex) AWS, Google Cloud Platform, OpenStack

Merit of Cloud/IaaS
Before After
Create Environment by Person Software Defined
Buy Hardware Resource on demand
Depend on Hardware Not depend on Hardware
Taking Time Linearly Repeat/Reproduce
Hardware Resource is Limited Resource is unlimited
Can NOT do everything! Can do EVERYTHING!

The Beginning of OpenStack
Nova
• IaaS platform NASA developed
for solving the scalability
problem of Eucalyptus
Swift
• Cloud storage service developed by
Rackspace
2010, Summer
Started “OpenStack Project”
with Nova and Swift targeting 100%
Open Source Software

OpenStack Ocata Release
■ One platform: bare metal, VMs, containers
– OpenStack provides one platform to orchestrate bare metal,
containers and virtual machines on a single network allowing
private users to optimize for their application without creating more
silos in their datacenter, and giving service providers more
capabilities.

OpenStack is..
