Ways to deploy Openstack● Linux packages

● DevOps Installers

● Developer Installers

● OpenStack as a Service

● Commercial Distributions

"A documented shell script to build complete OpenStack development environments."

Build your cloud in 4 steps:● Install Ubuntu 11.10 (Oneiric), 12.04 (Precise) or

Fedora 16● Download DevStack● Describe your configuration to localrc● Install running stack.sh

Installed and debugged:

○ Nova (LXC-based)○ Keystone○ Glance○ Horizon○ Quantum (OpenVSwitch, Linux Bridge)○ EC2 support

Problems you will face

● BUGS!● Finding complete up-to-date docs● Prerequisite knowledge (linux,virtualization)● Authenticating with keystone● Defining working images ● Booting images using nova-api● Using LXC with libvirt● Using LXC with libvirt through nova● Time is never your ally

Outline

● Openstack● Quantum● Our Experience● Conclusion

Conclusions

● Openstack is still evolving. Will be:○ More productive○ More automated○ More customizable

● Deployment in AWS:○ Interesting○ But very challenging

Future

● Explore Quantum

● Experiment with Quantum Plugins

● Fix LXC support

● Compare with KVM deployment
