v3.3.2-pre
Large scale computing has evolved since the present Computer Centre infrastructure and tools were designed to manage the first years of LHC data taking. Today we can see the scaling limitations of some of them and questions are raised over the role of traditional batch systems in the future; many tools and technologies exist in the public domain to manage facilities at large scale. This, together with changes to the way we will provide computing in the future, lead us to reassess the tools used to manage the infrastructure and the way in which services are managed.
The CERN Computer Centre will soon be extended with a remote facility, and virtualization and other technologies allow us to provide services in new ways. This talk will describe the work being done in IT to modernize the tools and infrastructure to allow us to manage machines and services at significantly larger scales than today, how we will make use of virtualization to more effectively use the computing resources, and the implications of the addition of a remote extension to the Computer Centre. It will also cover how we see cloud services playing a role in the future at CERN and how these can be seen as complementary to the grid and traditional services.
