OpenVZ Delivers Live Migration Capability In Latest Open Source Virtualization Software

Allows System Administrators To Move Virtual Servers Between Physical Servers Without End-User Disruption

The OpenVZ  project announced availability of its operating system-level server virtualization software in the form of a kernel based on Linux 2.6.9, including for the first-time in a stable branch, fully-tested and performance-tuned live migration and Virtual Ethernet device features. Previously, those features were only available in the development branch of OpenVZ software.

Delivery of the checkpointing and live migration functionality as part of OpenVZ brings a capability that no other open source operating system-level virtualization software offers. It allows system administrators to move virtual servers between physical servers without end-user disruption or the need for costly storage capacity.

With checkpointing and live migration, the state of a running virtual environment is frozen and the image stored on disk then restored on another server. The function executes between any two servers on a network, so the capability works for any server and any application. OpenVZ delivers this capability without additional requirements, such as a storage area network (SAN).

Also, the Virtual Ethernet device function allows for network devices to be created inside virtual environments using designated names and hardware (MAC) addresses that are different from the actual physical device.

"Now, the user community can enjoy rock-solid OpenVZ software with advanced features," said Kir Kolyshkin, manager of the OpenVZ project. "This represents months of work on performance tuning and quality testing to ensure delivery of stable software code."

OpenVZ is operating system-level server virtualization software technology, built on Linux, which creates multiple isolated, secure virtual environments on a single physical server – enabling greater server utilization and superior availability with fewer performance penalties. The virtual servers ensure that applications do not conflict and can be re-booted independently.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
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 ...
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...

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.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
