2. Sorry
My English is very poor.
Maybe, there are some spelling
miss and grammar problem in
this slide and my speaks.

3. This is just a toy
I’m rewrite the nova-compute by Java. What’s mean?
A picture is worth a thousand
words.
Let’s take a demo!!

4. Demo structure
OpenStack
Running the openstack on
Amazon EC2 by using
devstack
Amazon EC2
This is my localrc

5. Disable n-cpu??
This is key point
Where the nova-compute
running ?

6. My Windows laptop change to n-cpu
OpenStack
RabbitMQ
Amazon EC2
Internet
nova-compute

7. Technology Issue
• Which hypervisor do I use in Windows?
• VirtualBox
• This is an Open Source Hypervisor and provide HTTP based
API
• What feature do I implement in?
• Boot Server, Stop Server and Boot by volume.
• VirtualBox iSCSI API is not open to public.
• Is Neutron support?
• Completely unsupported!
• OpenFlow… Virtual switch… Linux Bridge…
• They are not work on windows.
• This project reach a dead end by Neutron.

8. Conclusion
• Java is not suite for OpenStack
• ex) JSON format
• Java needs static type in JSON
• Completely define the all JSON input and output
• Or, all treat as Object type
• Cast and Cast and Cast…
Like a computer
virus?
• One day, this program grow world wide
• All machine controlled by OpenStack
• Grid Computing and OpenStack?
