RIM Open Sources Carina Environment Manager for OpenNebula Clouds

Service provisioning and scalability on OpenNebula Clouds

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.

Last week RIM announced through the OpenNebula users mailing list the public availability of a first version of Carina as Apache licensed open-source software. The software, guides, and a variety of sample integrations with distributed middleware and tools like Tomcat, CloudFoundry, Jenkins and HBase are available for download at the Blackberry Github. Moreover there is a new appliance in the OpenNebula marketplace with all the dependencies already installed. This first version allows to automatically deploy, scale and manage the availability of multi-VM application clusters according to policies such as time of day, load-based, service priority, failure events, or custom metrics. The system ensures that an appropriate number of virtual machines are started even in the presence of hypervisor or data center failures to meet application service requirements. Carina is a relatively light-weight tool which is designed to be easy to understand, extensible and adaptable.

Today RIM has contributed its environment manager to the OpenNebula ecosystem and has written a post on the OpenNebula blog with a description of how RIM is using Carina and OpenNebula in their data centers, the features provided by Carina, and its future directions for the project with an open invitation to the OpenNebula community to participate in its development.

Enterprises are moving to the cloud faster than most of us in security expected. CIOs are going from 0 to 100 in cloud adoption and leaving security teams in the dust. Once cloud is part of an enterprise stack, it’s unclear who has responsibility for the protection of applications, services, and data. When cloud breaches occur, whether active compromise or a publicly accessible database, the blame must fall on both service providers and users. In his session at 21st Cloud Expo, Ben Johnson, C...

Today traditional IT approaches leverage well-architected compute/networking domains to control what applications can access what data, and how. DevOps includes rapid application development/deployment leveraging concepts like containerization, third-party sourced applications and databases. Such applications need access to production data for its test and iteration cycles. Data Security? That sounds like a roadblock to DevOps vs. protecting the crown jewels to those in IT.
