OpenNebula 4.4 Retina Bringing Simplicity to Enterprise Cloud Computing

Simple but feature-rich, customizable and open solution to manage enterprise private clouds

The OpenNebula Project has just announced the nineteenth stable release of its widely deployed OpenNebula cloud management platform, a fully open-source solution for data center management and enterprise cloud computing. With a sysadmin-centric approach, OpenNebula is the open operating system of choice in the converged data centre, combining a powerful virtualization manager that supports traditional IT features such as fault tolerance and failover, with the dynamic provisioning, elasticity and multi-tenancy of the enterprise cloud.

OpenNebula 4.4 Retina includes support for multiple system datastores, which enables the definition of scheduling policies for storage load balancing. The monitoring subsystem has switched from a pulling mechanism to a massively scalable pushing model, being now able to monitor hundreds of thousands of VMs in a few minutes. An important effort has been also made in enhancing the support for cloud bursting to Amazon, enabling a transparent offload of computing power whenever the local infrastructure cannot cope with the demand. Moreover, the Amazon EC2 and EBS interfaces implemented by OpenNebula have been revisited and extended to support new functionality.

"OpenNebula's roadmap is completely driven by users needs with features that meet real demands, not features that result from an agreement between IT vendors planning to create their own proprietary solution", said Ruben S. Montero, Chief Architect of OpenNebula. "An active and engaged community, along with our focus on solving real user needs in innovative ways and the involvement of the users in a really vendor-agnostic project, constitute the OpenNebula's recipe to success", said Ignacio M. Llorente, Director of OpenNebula.

With tens of thousands of deployments around the globe, OpenNebula is parked in some of the biggest organizations including research leaders like FermiLab, European Space Agency and SurfSARA, and industry leaders like Produban - Bank Santander, Akamai, CentOS, BBC, Blackberry and China Mobile. The first OpenNebula Conference, held in Berlin in October 2013, served as a meeting point of cloud users, developers, administrators and builders, and featured talks with experiences and use cases from these organizations.

IoT & Smart Cities Stories
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...

Business professionals no longer wonder if they'll migrate to the cloud; it's now a matter of when. The cloud environment has proved to be a major force in transitioning to an agile business model that enables quick decisions and fast implementation that solidify customer relationships. And when the cloud is combined with the power of cognitive computing, it drives innovation and transformation that achieves astounding competitive advantage.
Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
In his keynote at 19th Cloud Expo, Sheng Liang, co-founder and CEO of Rancher Labs, discussed the technological advances and new business opportunities created by the rapid adoption of containers. With the success of Amazon Web Services (AWS) and various open source technologies used to build private clouds, cloud computing has become an essential component of IT strategy. However, users continue to face challenges in implementing clouds, as older technologies evolve and newer ones like Docker c...
