Building Clouds on VMware vSphere This case study assumes you want to build a private cloud on top of an existing virtualized datacenter composed of multiple hosts running vSphere and managed by one or several instances of vCenter. It is understood that you do not want to abandon your investment in VMware by retooling the entire stack. You want to continue managing your infrastructure with already familiar and powerful VMware tools, such as vSphere and vCenter Operations Manager. Your goal is to create a self-service cloud environment on top of your vSphere infrastructure to provide your users with a simple cloud interface featuring elasticity, multi-tenancy and self-service provisioning. This post compares the pricing of two different approaches to build this cloud environment, the deployment of vOneCloud (an open-source replacement for vCloud based on OpenNebula) ... (more)

OpenNebula 3.6 Beta Cloud Management Toolkit Is Out

The OpenNebula project has just announced the availability of the beta release of OpenNebula 3.6 (Lagoon). OpenNebula 3.6 features a new hotpluging mechanism for disk volumes that supports attaching either volatile volumes or existing images to a running VM. OpenNebula 3.6 brings new Quota and Accounting tools, so now they are included in the OpenNebula core to enhance their integration with the existing AuthZ & AuthN mechanisms and other related tools (e.g. Sunstone). There are some other new features like VM rescheduling, hard reboots, cloning of disk images… OpenNebula 3.6 ... (more)

Building Private and Hybrid Clouds with Ubuntu 9.04

Ubuntu Workshop at Cloud Expo April 23, 2009  - Ubuntu 9.04 (Jaunty Jackalope) has been released today bringing highly interesting new features, specially in the Cloud Computing and Virtualization area. The new Ubuntu server distribution includes two complementary cloud tools, OpenNebula and Eucalyptus, so providing the technology required to build the three types of Cloud architectures, namely private, hybrid and public clouds. Eucalyptus can be used to transform an existing infrastructure into an IaaS public cloud, being compatible with Amazon’s EC2 interface. Eucalyptus is fu... (more)

Europe’s Largest Grid Project Moves Closer to Cloud-style Computing

The integration of two clans of computation, ‘grid’ and ‘cloud’ computing, is moving closer through collaboration between the projects Enabling Grids for E-sciencE (EGEE) and  Resources and Services Virtualisation without Barriers (RESERVOIR). The two teams will work together to explore how the institutes providing computing resources to EGEE could benefit from adopting a ‘private cloud’ model to provide resources. Private clouds allow organisations to easily manage their own hardware resources in-house. Using virtualization technology they can alter the provided computing to su... (more)

Interfacing Private Clouds with the libvirt Virtualization API

In my post "Interfaces for Private and Public Cloud Computing", I briefly described the main differences between public and private cloud computing from the perspective of their different application scope and interfaces. My position was that a private cloud interface should provide rich enough semantics, far beyond of that provided by public clouds (such as Amazon EC2 APIs), to ease the integration of the distributed virtual infrastructure in the data-center management stack, including user and administration support. Such interface should provide additional functionality for vi... (more)
