Europe's adoption of cloud computing lags behind the United States by about two years due to various cultural, legal, technological, business, and financial factors. OpenStack has the potential to become the dominant cloud platform in Europe if it provides ease of use, access, integration with existing infrastructure, and simplicity. A robust ecosystem of applications, services, and partners can help OpenStack overcome barriers to adoption by reusing existing investments, simplifying deployment and management, and allowing flexibility without disruption to businesses or business models.
