google app engine - Can I have multiple versions deployed on openshift? -


for research project comparing paas providers. i'm not sure following. on app engine can have multiple live versions of application. if have new version , deploy can reach on non-default url like: versionx.myapp.appspot.com. can use url test while running on paas. once i'm happy result change default version , visitors see changes.

i wondering if openshift has simular? thing found far deploys on git push , if fails build leave old version live. of course still leaves risk functional errors. if still have install test-server locally still doing system administration , nice if can prevented.

how best resolved when using openshift?

edit: did found article: https://www.openshift.com/blogs/release-management-in-the-cloud

is way or there other common ways this?

the best way re-create google functionality run dev/qa instance on separate gear , add git repositories remotes local git working copy, can git push environment testing before deploy production.
