OpenNebula 4.2 Beta Released

Multi-tier Cloud Application Orchestration and Auto-scaling

The OpenNebula Project has just announced the beta release of OpenNebula 4.2, the first update of the fourth series 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.

As usual OpenNebula releases are named after a Nebula. The Flame Nebula (catalogued as NGC 2024 and Sh2-277) is an emission nebula in the constellation Orion. It is located about 900 to 1,500 light-years away from Earth.

OpenNebula 4.2 gives users and administrators an easy way to create, publish, share, and manage multi-tier cloud applications and automatically define auto-scaling policies based on service level metrics and time schedule. The new service flow functionality converts an infrastructure cloud into a powerful environment for the execution of elastic business applications.

OpenNebula Flame also includes a more polished Sunstone interface, after its redesign in 4.0; with important usability enhancements. Datastore capacity is now monitored and used to limit the amount of storage size used by images. This is a first step to also control the runtime storage used by the VMs. The VMware backend has been completely redesigned with a more comprehensive storage scheme, more functionality and less dependencies. Also we have upgraded the Xen backend to support the new interfaces introduced in Xen 4.0. More details in its Release Notes.

OpenNebula 4.2 will be shown at OpenNebula Conference 2013, from 24 to 26 of September in Berlin. This first ever OpenNebula Conference will serve as a meeting point of cloud users, developers, administrators, builders, integrators and researchers, featuring talks with experiences and use cases from organizations like Produban – Bank Santander Group, China Mobile, FermiLab, Deutsche Post E-Post, European Space Agency, CentOS Project, Akamai, and BBC. The Conference agenda also includes a hands-on tutorial, lightning talks, and hacking and open space sessions that will provide an opportunity to present and discuss burning ideas, and meet face to face to discuss development.

Is advanced scheduling in Kubernetes achievable? Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations? In his session at @DevOpsSummit at 21st Cloud Expo, Oleg Chunikhin, CTO at Kublr, will answer these questions and demonstrate techniques for implementing advanced scheduling. For example, using spot instances ...

As hybrid cloud becomes the de-facto standard mode of operation for most enterprises, new challenges arise on how to efficiently and economically share data across environments. In his session at 21st Cloud Expo, Dr. Allon Cohen, VP of Product at Elastifile, will explore new techniques and best practices that help enterprise IT benefit from the advantages of hybrid cloud environments by enabling data availability for both legacy enterprise and cloud-native mission critical applications.

When it comes to cloud computing, the ability to turn massive amounts of compute cores on and off on demand sounds attractive to IT staff, who need to manage peaks and valleys in user activity. With cloud bursting, the majority of the data can stay on premises while tapping into compute from public cloud providers, reducing risk and minimizing need to move large files. In his session at 18th Cloud Expo, Scott Jeschonek, Director of Product Management at Avere Systems, discussed the IT and busine...
Organizations do not need a Big Data strategy; they need a business strategy that incorporates Big Data. Most organizations lack a road map for using Big Data to optimize key business processes, deliver a differentiated customer experience, or uncover new business opportunities. They do not understand what’s possible with respect to integrating Big Data into the business model.
Companies are harnessing data in ways we once associated with science fiction. Analysts have access to a plethora of visualization and reporting tools, but considering the vast amount of data businesses collect and limitations of CPUs, end users are forced to design their structures and systems with limitations. Until now. As the cloud toolkit to analyze data has evolved, GPUs have stepped in to massively parallel SQL, visualization and machine learning.
Recently, REAN Cloud built a digital concierge for a North Carolina hospital that had observed that most patient call button questions were repetitive. In addition, the paper-based process used to measure patient health metrics was laborious, not in real-time and sometimes error-prone.
