The Carina Environment Manager is a service management tool developed by Research In Motion (RIM) that allows for the automated deployment, elastic scaling and high-availability management of interconnected application clusters based on policies on OpenNebula clouds. The Carina project was motivated by the need to speed up the deployment of services onto the OpenNebula private cloud at RIM. Different teams are in the process of on-boarding their services, which are composed of multiple scale-out clusters that are networked together, onto RIM’s OpenNebula-based cloud. Thanks to Carina, these services will operate in an elastic and highly available manner in order to take advantage of the flexibility to rapidly provision new machines.
