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 pro... (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...
