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 has just announced the beta release of its version 4.8, code named
Lemon Slice, which brings significant improvements in different aspects.
Sticking with its vision of bringing simplicity to cloud management, this
release comes with improvements in the recently added Cloud View portal,
designed for end users. One significant advantage of the new portal is the
ability to control flows, groups of interconnected Virtual Machines that
conform a service. Based on this Cloud View, a Virtual Datacenter
administrators view has been included (VDCAdmin View), which enables VDC ... (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)
This is the second article covering the functionality provided by the new
OpenNebula Zones (oZones) component available in the third major release of
OpenNebula. In a previous article, we described its Virtual Data Center
(VDC) functionality that is helping many IT organizations make the transition
toward the next generation of cloud infrastructures supporting multiple
fully-isolated VDCs with advanced multi-tenancy. This article elaborates on
its support for building multi-tier cloud architectures consisting of
multiple OpenNebula Zones.

The OpenNebula Project has just announced the beta release of OpenNebula 4.2,
the first update of the fourth series of its widely deployed OpenNebula cloud
management platform, a fully open-source solution for data center management
and enterprise cloud computing. With a sysadmin-centric approach, OpenNebula
is the open operating system of choice in the converged data centre,
combining a powerful virtualization manager that supports traditional IT
features such as fault tolerance and failover, with the dynamic provisioning,
elasticity and multi-tenancy of the enterprise cloud.
