Public clouds get the headlines, but private clouds are alive and well for businesses that want to keep a tight grip on their data. So, OpenStack, the leading Infrastructure-as-a-Service (IaaS) cloud software, stackers are happy to welcome Ussuri, the 21st version of this open-source cloud infrastructure software stack.
OpenStack isn’t just private clouds, though. OpenStack software now powers more than 75 public cloud data centers and thousands of private clouds with over 10 million compute cores. A major reason for its popularity is it can be deployed on multiple architectures: Bare metal, virtual machines (VMs), graphics processing units (GPUs), and containers.
