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)
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)
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)
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)
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)
