Is there any free online maven repository?

Question

Is there any free online private maven2 or maven3 repository? So that team can access the repository from various region.

Answer 1

I recently wrote a lightweight Google App-Engine application to host my private repositories, backed by Google Cloud Storage (which is multi-regional per default):

Thanks to Google App-Engine free quotas, and depending on the scale needed, you won't have to pay anything.
