External Collaboration in SharePoint Online 2013

I have seen the future and it’s SharePoint Online 2013. I am not totally biased because I love Office 365. A lot has changed since the BPOS days. SharePoint Online 2007 was a start for Microsoft in the Enterprise Cloud business. The platform was descent and many customers were able to create Intranet portals. There were some issue such as no search over multiple site collections and no My Sites. The next step was Office 365 and SharePoint Online 2010. The gap with the big on premise brother became even smaller. A couple years later we get another update: SharePoint Online 2013 and the gap is almost gone. The new online version comes with a set of features that enables external collaboration with customers or partners.
