LinuxCon Japan is the premiere Linux conference in Asia that brings together a unique blend of core developers, administrators, users, community managers and industry experts.
CloudOpen Japan is a conference celebrating and exploring the open source projects, technologies and companies who make up the cloud. It’s built on a belief that open works: for users, for industry and for technology.
OpenStack is one of the most popular Open Source IaaS infrastructure software. Commercial use of OpenStack is already started including large scale environments. By the large number of developer participation, features of OpenStack is evolving with six month release cycle. Increasing number of features itself is great, but for user's viewpoint, it is necessary to consider compatibility between newer and older version to safely upgrade and continue to operate the cloud infrastructure.
This talk will discuss the compatibility issues such as databases, APIs, configuration files, and possible solutions such as compatibility tests, increasing API test coverage and so on. This talk will be intended for developers/users who are interested in developing and using OpenStack.
