If you're a system administrator, you've probably already heard of Cfengine, a cross-platform datacenter automation framework used by more than 5,000 companies on millions of machines worldwide. With Cfengine, the sysadmin describes the desired system state and Cfengine takes care of the rest: it will install packages, maintain configuration files, keep permissions and ensure the right processes are running according to your policy. A couple of months ago, Cfengine presented a brief overview of the possibilities of a Cfengine-managed OpenNebula setup at the Large Installation System Administration (LISA) conference in San Jose. The Cfengine team presented how Cfengine may be used on both the physical and virtual sides of an OpenNebula-based cloud. More specifically, they presented how Cfengine can be used to install and configure the physical infrastructure in an O... (more)

Eucalyptus, CloudStack, OpenStack & OpenNebula: A Tale of Two Cloud Models

Over the last five years, since the release of the first open-source version of OpenNebula in March 2008, we have been involved in many presentations, discussions and meetings where people wanted to know how OpenNebula compares with the rest of open-source Cloud Management Platforms (CMPs), mostly with Eucalyptus and OpenStack. The most common understanding is that all CMPs are competing in the same market, trying to fill the same gap. Consequently, people jump to the wrong conclusion that after years of a fierce competition, there will only be one winner, a single open-source CM... (more)

Cloud Computing in Ubuntu

The Ubuntu team announced one month ago their plan to offer a set of new software packages related to cloud computing in Ubuntu 9.04 (Jaunty Jackalope), due to be released in April 2009. One of the target packages, the OpenNebula Virtual Infrastructure Engine, is available for download from the Ubuntu repository. Ruben S. Montero has published a very nice "mini how-to" describing how to set up your own private cloud in only five steps with Ubuntu and OpenNebula. This is the easiest and fastest way to transform a static and rigid physical infrastructure into a flexible, elastic a... (more)

BoF Session on Cloud Computing API at Open Grid Forum 25

A BoF ("birds of a feather") session on Cloud Computing API was organized at Open Grid Forum 25 in Catania (Italy). The session focused on the charter and the creation of a Group inside OGF to work on the development of an API specification for the dynamic deployment, using an appropriate descriptor language, control and monitor of virtual machines. The scope of the specification will be all the high level functionality required for the life-cycle management of virtual machines which is needed to support automated service elasticity. The new specification will facilitate the in... (more)

OpenNebula 4.0 Beta Enterprise Cloud Management Platform Is Out

The OpenNebula Project has just announced the beta release of the fourth major version of its widely deployed OpenNebula cloud management platform, a fully open-source enterprise-grade solution to build and manage virtualized data centers and enterprise clouds. The project has come a long way since the first “technology preview” of OpenNebula five years ago. This latest release is the realization of a vision of simplicity, openness, code-correctness and a sysadmin-centric approach. OpenNebula 4.0 brings valuable contributions from many of its thousands of deployments that includ... (more)
