Here are e-mail threads which keeps the history of LBaaS decisions:
LBaaS IIRC meeting minutes:
LBaaS e-mail discussion:
As you see there was a comparison of existed at that moment LBaaS solutions:
* Mirantis LBaaS
* eBay LBaaS
Git history shows that the initial commit for Libra was on September 10th
2012. This commit contains few files without any LBaaS functionality.
I think it is quite fair to say that OpenStack community did a great job on
carefully evaluating existing and working LBaaS projects and made a
decision to add some of existing functionality to Quantum.
