In Case You Missed It

PayPal’s Sri Shivananda shared the company’s latest milestone on the [PayPal blog]( https://www.paypal-community.com/t5/PayPal-Forward/PayPal-s-Front-End-Cloud-Powered-by-OpenStack/ba-p/959621?utm_source=twitter&awesm=awe.sm_fMRJb&utm_content=13611975&utm_medium=social#.VRHODimi0j0.twitter). PayPal has converted nearly 100 percent of its traffic serving web/application program interface apps and mid-tier services to run on its OpenStack-based private cloud. “OpenStack has been a key choice in our journey to drive agility and operational efficiencies,” says Shivananda. "In leveraging open source technology, it’s important that we engage with the community. We’re doing so as an active contributor to several OpenStack projects"

HP Helion’s Stephen Walli gives a great account as to why OpenStack is different from other open source projects. "Openstack is going through forced growth in a time frame that is a 20%-25% of the time of other large-scale successful open source-licensed infrastructure projects. Openstack continues to demonstrate enormous growth and participation," notes Walli.
