"OpenStack has launched its 32nd major release, called Flamingo. The open source cloud platform is taking a clear step towards modernization, as one of the most significant changes is the complete removal of the Eventlet library. Eventlet was developed almost two decades ago to enable concurrency in Python. This was at a time when the language itself did not yet have async capabilities. Over the years, this feature has become obsolete, and its maintenance has been neglected."
"A concrete result is evident in the bare-metal module, Ironic. From now on, it can run as a fully-fledged multi-threaded application, which improves performance and scalability. This is more than just an internal clean-up: it opens the door to more reliable and faster bare-metal provisioning, a crucial feature for organizations that deploy their cloud infrastructure on a large scale. The Flamingo release includes a total of more than 8,000 changes, but it is the strategic implications that stand out most."
"OpenStack is explicitly positioned as an alternative to VMware, a scenario that is becoming increasingly attractive due to the uncertainty surrounding the future of that platform. Additionally, Flamingo aims to make OpenStack more attractive for modern workloads in the fields of artificial intelligence, machine learning, and high-performance computing. OpenStack is currently running on more than 55 million cores worldwide in production environments."
Flamingo is OpenStack's 32nd major release and removes the legacy Eventlet library to modernize concurrency handling. Eventlet, developed nearly two decades ago, became obsolete as Python gained async features and created maintenance and compatibility risks. The removal enables components such as Ironic to run as true multi-threaded applications, improving performance, scalability, and bare-metal provisioning reliability for large-scale deployments. Flamingo comprises over 8,000 changes and explicitly positions OpenStack as an alternative to VMware while targeting AI, machine learning, and high-performance computing workloads. OpenStack runs on more than 55 million cores in production, and Flamingo aims to expand that base while preparing the platform for the next fifteen years.
