One of the desirable properties which users expect in a modern cloud-hosted application is portability. Users want to migrate portable applications between private and public clouds or between different cloud regions. With container images as portable application implementations and emerging sophisticated container runtimes, this should be an easy task. But when a containerised application starts to become more complex, a container platform or an orchestration tool needs to be deployed. This add specifics blueprints and together with the persistent data makes the migration of the application tough. This means that the application is not in a condition to be moved as easily between clouds or even between the orchestration tools or container platforms, losing the desirable portability property. With the idea in mind that the next generation of Cloud-Native Applications must be deployable to different cloud providers as the requirements change, we are proud to announce the first proof of concept release of os2os, a tool to migrate cloud-native applications between OpenShift installations. While our research on application migration is not limited to this single container platform, we see it as one of the more popular and technically interesting ones.
