The need for containers in OpenStack

OpenStack is used by a large number of organizations. Cloud infrastructure vendors have called OpenStack an open source alternative to Amazon Web Services for organizations aiming to maintain a private cloud but with public cloud scalability and agility. OpenStack is popular for Linux-based Infrastructure as a Service (IaaS) offerings. As containers are gaining popularity, it's become necessary for OpenStack to provide various infrastructure resources such as computing, networking, and storage to containers. Rather than creating new vertical silos to manage containers in their data centers, developers and operators can find value in providing a cross plate-form API to manage virtual machines, containers, and bare metals.
