One of the goals of cloud computing is to allow developers to reduce the complexity of understanding and managing the hardware and software infrastructure so that they can focus on the functionality of the application. This goal has been achieved to varying degrees through the infrastructure, the service (IaaS) cloud and Peace Platform (PaaS)
have been successful.
Today, with more than 189 organizations and more than 9,100 individuals involved, OpenStack is the world's largest active open source and cloud project community. This massive global collaboration between developers and cloud computing technicians is designed to create a ubiquitous infrastructure as a service (IaaS) Open-source cloud Platf
