PayPal is the world's most successful e-commerce payment platform.
In Fall of 2012 PayPal embarked on a pilot OpenStack project aimed at transforming its global infrastructure into an agile, open and robust cloud platform.
Today the first PayPal production applications are running on OpenStack. By end of fall 2013, we expect several thousand instances in production supporting web and mid-tier applications. Along the way, PayPal solved several technical challenges making OpenStack high available, scalable and easy to operate at scale.
