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)

Grids and Cloud as Complementary Computing Paradigms

This is the title of the new GridBriefing just released by GridTalk to introduce Grids and Clouds as complementary computing paradigms. A clear understanding of their relationship will help the development and efficient use of existing academia and commercial e-infrastructures. It is especially interesting the table comparing Grid and Clouds side by side, as well as the strategy recommended in the chapter devoted to Grids and Clouds of the new white paper by the e-Infrastructure Reflection Group to ensure a healthy future for European e-infrastructures: Investigate the integrati...

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)

High Performance and Grid Computing in the Cloud

The HPCcloud discussion group has been created in order to address the growing interest in High Performance Computing and Grid Computing in the Cloud. The purpose of this group is to present experiences and scenarios by individuals, organizations and projects to illustrate how Cloud computing can enhance the different types of distributed and high performance computing infrastructures in science and engineering. The group covers the following aspects about innovative potential, benefits and challenges of new Cloud technologies and services in High Performance Computing (HPC) and ... (more)

A Flexible and Interoperable Cloud Operating System

OpenNebula Cloud on Ulitzer Future enterprise data centers will look like private clouds supporting a flexible and agile execution of virtualized services, and combining local with public cloud-based infrastructure to enable highly scalable hosting environments. The key component in these cloud architectures will the cloud management system, also called cloud operating system (OS), being responsible for the secure, efficient and scalable management of the cloud resources. Cloud OS are displacing "traditional" OS, which will be part of the application stack. Flexibility in Cloud ... (more)
