The document provides an overview of OpenStack presented by Takashi Torii at a seminar in Myanmar in August 2017. It begins with an introduction to cloud computing concepts like IaaS, PaaS, and SaaS. It then discusses what OpenStack is, including its origins, projects, architecture, and releases. The remainder covers the OpenStack community and user groups globally, the OpenStack Foundation and events, and opportunities for using and contributing to OpenStack.

5. What is Cloud?
■From user’s view
– On-Demand
– Pay-per-Use
■From operator’s view
– Standardized
– Low cost operation
6. Use Case
■Past Test Search System
– Purpose
●Students can search past test of each professor
and course
●Study easy! and help to take points!
– Requirement
●On the web
●Limited access
●Temporary
●Free or low cost
9. Software as a Service
(SaaS)
Using application in Cloud
Ex) Google Apps
10. Platform as a Service
(PaaS)
Using Cloud environment to develop applications
Ex) CloudFoundry
11. Infrastructure as a Service
(IaaS)
Using infrastructure (server, network, storage) in Cloud
Ex) AWS, Google Cloud Platform, OpenStack
12. Cloud Service

13. 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!

16. 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

18. 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.
