OpenNebula 4.6 Beta Released

On-demand Provisioning of Virtual Data Centers

The OpenNebula project has just announced the availability of OpenNebula 4.6 Beta (Carina). This release brings many new features and stabilizes features that were introduced in previous versions.

OpenNebula 4.6 introduces important improvements in several areas. The provisioning model has been greatly simplify by supplementing user groups with resource providers. This extended model, the Virtual Data Center, offers an integrated and comprehensive framework for resource allocation and isolation.

Another important new feature has taken place in the OpenNebula core. It has undergone a minor re-design of its internal data model to allow federation of OpenNebula daemons. With OpenNebula Carina your users can access resource providers from multiple data-centers in a federated way.

With Carina the OpenNebula team has started a journey to deliver a more intuitive and simpler provisioning experience for users. Their goal is level the final user usability with the system administration and operation ones. First, the Sunstone graphical interface has been tweaked to help the user workflows. It has also been improved in order to support the new Marketplace version, which makes even easier for a user to get a virtual application up and running.

Finally, some other areas has received the attention of the OpenNebula developers, like for example a better `Gluster <gluster_ds>` support through libgfapi, improved access to large pools pagination, or optionally limit the resources exposed by a host, among many others are included in Carina.

As usual OpenNebula releases are named after a Nebula. The Carina Nebula (NGC 3372) is one of the largest nebulae the sky. It can only be seen from the southern hemisphere, in the Carina constellation.

The OpenNebula Project thanks the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.

One of the biggest impacts of the Internet of Things is and will continue to be on data; specifically data volume, management and usage. Companies are scrambling to adapt to this new and unpredictable data reality with legacy infrastructure that cannot handle the speed and volume of data. In his session at @ThingsExpo, Don DeLoach, CEO and president of Infobright, will discuss how companies need to rethink their data infrastructure to participate in the IoT, including: Data storage: Understanding the kinds of data: structured, unstructured, big/small? Analytics: What kinds and how responsiv...
Since 2008 and for the first time in history, more than half of humans live in urban areas, urging cities to become “smart.” Today, cities can leverage the wide availability of smartphones combined with new technologies such as Beacons or NFC to connect their urban furniture and environment to create citizen-first services that improve transportation, way-finding and information delivery. In her session at @ThingsExpo, Laetitia Gazel-Anthoine, CEO of Connecthings, will focus on successful use cases.
Sensor-enabled things are becoming more commonplace, precursors to a larger and more complex framework that most consider the ultimate promise of the IoT: things connecting, interacting, sharing, storing, and over time perhaps learning and predicting based on habits, behaviors, location, preferences, purchases and more. In his session at @ThingsExpo, Tom Wesselman, Director of Communications Ecosystem Architecture at Plantronics, will examine the still nascent IoT as it is coalescing, including what it is today, what it might ultimately be, the role of wearable tech, and technology gaps stil...
The true value of the Internet of Things (IoT) lies not just in the data, but through the services that protect the data, perform the analysis and present findings in a usable way. With many IoT elements rooted in traditional IT components, Big Data and IoT isn’t just a play for enterprise. In fact, the IoT presents SMBs with the prospect of launching entirely new activities and exploring innovative areas. CompTIA research identifies several areas where IoT is expected to have the greatest impact.
Wearable devices have come of age. The primary applications of wearables so far have been "the Quantified Self" or the tracking of one's fitness and health status. We propose the evolution of wearables into social and emotional communication devices. Our BE(tm) sensor uses light to visualize the skin conductance response. Our sensors are very inexpensive and can be massively distributed to audiences or groups of any size, in order to gauge reactions to performances, video, or any kind of presentation. In her session at @ThingsExpo, Jocelyn Scheirer, CEO & Founder of Bionolux, will discuss ho...

The IoT market is projected to be $1.9 trillion tidal wave that’s bigger than the combined market for smartphones, tablets and PCs. While IoT is widely discussed, what not being talked about are the monetization opportunities that are created from ubiquitous connectivity and the ensuing avalanche of data. While we cannot foresee every service that the IoT will enable, we should future-proof operations by preparing to monetize them with extremely agile systems.
There’s Big Data, then there’s really Big Data from the Internet of Things. IoT is evolving to include many data possibilities like new types of event, log and network data. The volumes are enormous, generating tens of billions of logs per day, which raise data challenges. Early IoT deployments are relying heavily on both the cloud and managed service providers to navigate these challenges. Learn about IoT, Big Data and deployments processing massive data volumes from wearables, utilities and other machines.
