27 Mar 2015 Mark Hinke: An Overview of Cloud Computing Architectures - Thursday April 9th @NSU [41655]
Einstein's from 6:30PM to 7:30PM; Presentation at 7:30PM

This crash course is designed to give an overview of cloud computing architecture and the open source software that can be used to deploy and manage a cloud computing environment.

Speaker: Mark R. Hinkle, Senior Director, Open Source Solutions, Citrix Systems

Please RSVP at

Topics to be discussed in this session will include virtualization (KVM, LXC, and Xen Project), orchestration (Apache CloudStack, Eucalyptus, Open Nebula, and OpenStack), and storage (GlusterFS, Ceph, and others). The talk will also provide insight into how to deliver Platform-as-a-Service (PaaS) and what technologies can be used to compliment this evolving cloud computing paradigm.

Systems administrators and IT generalists will leave the discussion with a general overview of the options at their disposal to effectively build and manage their own cloud computing environments using free and open source software and understand the capabilities and benefits of a host of technologies.

06 Nov 2014 Oracle VM.Built for Virtualizing Enterprise Applications [39248]
White Paper (10-pages)

Virtualization technologies offer well-established benefits: consolidation, improved utilization, and greater IT flexibility in applying resources to workloads. But Oracle VM is the only virtualization solution that Oracle tests extensively at extreme scale and fully certifies for Oracle Database deployments on x86 servers.

Oracle VM is designed specifically for Tier-1 applications deployed as virtual guests. Oracle continues to make design decisions in line with enterprise requirements for security, performance, scalability, stability, and supportability. The lightweight Xen hypervisor offers clear advantages for security, reliability, and performance. Open source Xen and Linux technologies enhance the product's stability, providing a strong code base to which Oracle and other community developers can contribute ongoing security, performance, and reliability improvements. And lastly, the cost model for Oracle VM helps IT managers conserve today's shrinking budgets. Oracle VM is free to download and use, and Oracle charges only a low annual fee for enterprise support...

12 May 2014 How to install Oracle VM server (x86)? [36390]
Step By Step Guide

Lingeswaran writes, "Oracle VM for X86 is a native hypervisor which is directly runs on the host's hardware. This hypervisor is based on xen technology and it requires very small footprint on the hard drive to install it. Oracle VM server is directly installed on the baremetal computer and it contains the oracle VM agent to manage the communication with oracle VM manager. By default, this hypervisor system is called dom0 (Domain zero) which also be called privileged domain since it has direct access with hardware. Virtual machines will be called as domU which is unprivileged domain and doesn't have direct control on the hardware..."
