What is OpenStack?
OpenStack is a free and open-source software platform for cloud computing, mostly deployed as an infrastructure-as-a-service (IaaS). It is a popular choice for building private and public clouds, and is widely used by organizations of all sizes. OpenStack provides a scalable and flexible platform for managing compute, storage, and networking resources, making it an ideal choice for virtualization and containerization.
OpenStack was founded in 2010 by Rackspace Hosting and NASA, and has since grown to become one of the largest and most active open-source communities in the world. With over 500 contributing companies and 20,000 individuals, OpenStack is constantly evolving and improving to meet the needs of its users.
