Behind every cloud service or cloud-based solution, there are real people... A robust ecosystem of solutions providers has emerged around cloud computing. But who are the CEOs & CTOs behind those providers, who are the internal and external entrepreneurs driving companies involved in the Cloud, who are the leading engineers, developers, analysts, researchers, marketing professionals, authors...who, in short, are the people behind the cloud? This list will be updated weekly between now and November 4-7, 2013, when 13th Cloud Expo | Cloud Expo Silicon Valley opens its doors in the Santa Clara Convention Center, in the heart of California's Silicon Valley. Here are some highly prominent "Cloud People" to kick off with... RANDY BIAS | @randybias "Randy Bias is visionary. He sees things others don't." [Emphasis added.] That is how Mårten Mickos puts it, as succinctly as ever.... (more)

OpenStack Hits First Milestone

Three months after publicly starting down the road to imprint its NDA on the cloud by establishing a large-scale open source cloud platform called OpenStack free for anybody to use, Rackspace Hosting, its BFF NASA and a reportedly growing OpenStack community made their first official code drop Thursday. The milestone is called Austin - they're doing this alphabetically so presumably they have a ways to go - and it includes the all-important Amazon EC2-challenging OpenStack Compute provisioning engine that's supposed to blend the best of the Rackspace Cloud Servers widgetry that underlies its public cloud offering with NASA's own home-made Nebula cloud platform. OpenStack Compute, which has commanded most of the work these last few months, is the engine that provisions virtual machines complements of either Xen or KVM and basically supplies the glue that holds a clo...

The Role of Cloud Computing

Let me show how I see Cloud (and virtualization as enabling technology) and Grid as complementary technologies that will coexist and cooperate at different levels of abstraction in future infrastructures. I will first clearly state my position about Cloud and Grid, which are complementary technologies. There is a growing number of posts and articles trying to show how cloud computing is a new paradigm that supersedes Grid computing by extending its functionality and simplifying its exploitation, even announcing that Grid computing is dead. It seems that new technologies and paradigms have always the mission objective to substitute existing ones. Some of these contributions do not fully understand what grid computing is, focusing their comparative analysis on simplicity of interfaces, implementation details or basic computing aspects. Others posts define Cloud in th... (more)

OpenNebula vs. OpenStack: User Needs vs. Vendor Driven

This post is a reprint of a post at OpenNebula.org We've crafted this post to answer a recurring question we've been hearing lately, specially from organizations planning to build their own private cloud: How do you compare OpenNebula with OpenStack?... This is indeed a complex question. There is no single answer because open-source projects and technologies present several dimensions. But we are far from afraid to answer it: the short, tl;dr version would be that they represent two different open-source models. While OpenNebula is an open-source effort focused on user needs, OpenStack is a vendor-driven effort. This is neither a question of one being better than the other, they simply represent different approaches. Let us compare both open source options based on the following criteria: internal organization, governance model, roadmap definition, contributor pro... (more)

Interfaces for Private and Public Cloud Computing

An entire ecosystem is evolving around cloud computing. Interface standardization efforts, commercial products, cloud infrastructure and management services, virtual appliance providers and open-source solutions are filling niches in the cloud ecosystem. The role and position of a component or a service in the ecosystem are defined by its capabilities, the consumers of those capabilities and its relationship with other components and services. This article presents public and private cloud computing from the perspective of their different application scope and interfaces. Interfaces for Public Cloud Computing Public or external clouds offer virtualized resources as a service, enabling the deployment of an entire IT infrastructure without the associated capital costs, paying only for the used capacity. Amazon EC2,ElasticHosts, GoGrid and FlexiScale are examples of comm...

OpenNebula Cloud Computing Topic Launched on Ulitzer

OpenNebula Cloud topic launched today on Ulitzer, as the leading information source for this open source Cloud Computing platform. OpenNebula, which was was born as a research project in 2005 by Dr. Rubén S. Montero,  Dr. Ignacio M. Llorente, is an open and flexible tool that fits into existing data center environments to build any type of Cloud deployment. OpenNebula can be primarily used as a virtualization tool to manage your virtual infrastructure in the data-center or cluster, which is usually referred as Private Cloud. OpenNebula supports Hybrid Cloud to combine local infrastructure with public cloud-based infrastructure, enabling highly scalable hosting environments. OpenNebula also supports Public Clouds by providing Cloud interfaces to expose its functionality for virtual machine, storage and network management. The OpenNebula Cloud Toolkit is a widely used o... (more)

StratusLab - European Initiative to Integrate Cloud with Grid Technologies

Researchers from a collaboration of six European organisations have attracted funding worth €2.3million to develop a new Internet-based software project called StratusLab. The two year project, headed up by Project Coordinator Dr Charles Loomis from CNRS, was launched in Paris on the 14th of June 2010. It aims to enhance distributed computing infrastructures, such as the European Grid Infrastructure (EGI), that allow research and higher education institutes from around the world to pool computing resources. Funded through the European Union Seventh Framework Programme (FP7), the two year project aims to successfully integrate ‘cloud computing’ technologies into ‘grid’ infrastructures. Grids link computers and data that are scattered across the globe to work together for common goals, whilst cloud computing makes software platforms or virtual servers available as a ... (more)

NASA's Nebula Cloud Technology to Play Key Role in Open Source Initiative

The core technology developed for NASA's Nebula cloud computing platform has been selected as a contributor for OpenStack, a newly launched open source cloud computing initiative. It will pull together more than 25 companies to play a key role in driving cloud computing standards for interoperability and portability. Cloud computing is a way to deliver computing resources, such as software, storage and virtual computing power, as services over the Internet. NASA launched the Nebula cloud computing platform to provide agency researchers with a range of services powerful enough to manage NASA's large-scale scientific data sets. Nebula offers unparalleled compute capability, storage and bandwidth to users at NASA's Ames Research Center in Moffett Field, Calif., and Goddard Space Flight Center in Greenbelt, Md. "We hope that OpenStack will form the foundation of a new o... (more)

More details (and screenshots) soon at the OpenNebula blog. ... (more)

Why Is OpenNebula the Solution for Private Cloud Computing?

OpenNebula comes with several characteristics that makes it a unique software for the management of private clouds. This is actually not a mere coincidence, but rather a consequence of the design principles followed by the OpenNebula team at the time of creating the architecture and whenever a new feature is planned. So, without a shred of a doubt, we can claim that OpenNebula has the ability of managing Private Clouds embedded in its DNA. Let’s see the three stronger points of OpenNebula when managing a local set of physical and virtual resources, for in-house consumption: Data models adjusted to the datacenters. The entities that OpenNebula work with, as abstractions of the physical and virtual resources, are a reflection of the typical resources found in traditional datacenters. In this way, the command-line interface (CLI) and the APIsoffered by OpenNebula are ab... (more)
