The document discusses the OpenStack Kilo release from the OpenStack Foundation. Some key points: - Kilo aimed to create a stable core platform for interoperability and integrating new technologies. - It focused on defining stable core services and saw key growth in integrated projects like Ironic for bare-metal provisioning. - Major components like Nova, Keystone, Glance, Cinder, Neutron, Ceilometer, and Horizon received new features, improvements, and bug fixes related to areas like performance, security, manageability and advanced networking services. - The discussion section raises questions about factors that would motivate upgrading to Kilo like improved stability, performance and flexibility, and challenges that may come with

- performance, scalability
- flexibility, manageability
- interoperability
- …
2. Which features we currently lack of, and has implemented in Kilo?
3. Which bugs we haven't fixed yet, but resolved in Kilo?
17

18. Questions
4. If upgrade, …
- what challenges we have to overcome?
- what impacts we have to deal with?
- how much budget (time, human) we need?
5. If not upgrade, …
- DIY everything!
- waiting for a release more preferable than Kilo?
