Open Source Summit Japan

Today many OSS services provide APIs and users can extend their applications for catching business opportunities.
For example, Mesos and OpenStack provides REST APIs and users can deploy applications on these clouds.

On cloud-native APPs, users want to switch between public and private clouds for cost-efficiency, high-performance, etc. However, users face an interoperability issue at the time.
In general, developers consider that backwards compatible changes are not painful and cloud providers tend to customize the OSS by adding some features. However, backwards compatible changes also are painful against the interoperability, because users cannot switch to different cloud if the application depends on the provider's features.

In this talk, the speaker will explain how to keep OpenStack interoperability and get ideas from different OSS for stable interoperability.
