Cells allows Nova to scale to thousands of compute nodes through database and message queue sharding which helps eliminate single points of failure and enables failure domain segregation. They have been used by the largest OpenStack Clouds, however missing features, lack of testing, complex configuration and duplicated code paths, have limited wide adoption. During recent cycles the Nova project has been working on """"Cells version 2"""", a different approach to solve the same problem which is
