As you may know, OpenNebula's approach to cloud bursting (that is, its hybrid cloud model) is quite unique. The reason behind this uniqueness is the transparency to both end users and cloud administrators to use and maintain the cloud bursting functionality. The transparency to cloud administrators comes from the fact that a an AWS EC2 region is modelled as any other host (albeit of potentially a much bigger capacity), so the scheduler can place VMs in EC2 as it will do in any other local host. Of course, the scheduler algorithm can be tuned so the EC2 host (or hosts, more on this below) is picked last, so it will be only used only if there is a real need (ie, the local infrastructure cannot cope with the demand). On the other hand, the transparency to end users is offered through the hybrid template functionality: the same VM template in OpenNebula can describe th... (more)

Researching Cloud Resource Management and Use: The StratusLab Initiative

Formed by CNRS/LAL, GRNET, SixSq Sàrl, and UCM, StratusLab is an informal, open collaboration that focuses on the use cloud technologies in research and commercial environments and on the management of cloud resources in those environments. The key issue with productive use of the technologies is effective management of the cloud resources. For broad adoption, cloud resources must be manageable with the same (or similar) techniques currently used by administrators of data centres. The initial activities of the collaboration will investigate how different management techniques ca... (more)

Release of RESERVOIR Cloud Stack

RESERVOIR, flagship of European projects in cloud computing technology coordinated by IBM, has just announced the release of its cloud stack featuring Claudia Service Manager (Telefonica’s tool for automatic management of service scalability), OpenNebula Cloud Toolkit and security services for cloud federation. The RESERVOIR Cloud Stack supports the delivery of services on an on-demand basis, across countries, at competitive costs and without requiring a large capital investment in infrastructure. RESERVOIR enables the migration of resources across distributed administrative do... (more)

OpenNebula Publishes Its Quality Assurance and Testing Procedures

The OpenNebula Project has just published its Quality Assurance & Testing procedures. OpenNebula QA is the part of the OpenNebula project which covers all testing of the software that makes up an OpenNebula release. Its goal is to improve the quality of OpenNebula releases and updates. Testing & QA of a cloud management tool is particularly challenging as it requires to verify the integration of multiple software components, from different hypervisors and storage architectures to operating systems and DB backends. As part of OpenNebula QA we perform the following activities: Dev... (more)

A Strategic Framework for Cloud Migration

I am often asked about the steps to be taken and the issues to be considered for a successful migration to cloud computing. There is no magic formula to it, the specific steps will depend on your internal structure, industry and differentiation in the market. As general framework, I usually recommend the Decision Framework for Cloud Migration described in the Federal Cloud Computing Strategy together with a thorough study and comparison of cloud providers tailored to your needs and requirements. The three main guidelines would be: Shifting from Infrastructure to Service Manageme... (more)
