"customised data centre solutions and managed IT services"

"The Grid", in this context, really means a collection of infrastructure based on standards that will allow researchers to use remote, probably large, compute and data engines without having to know specific details about them. With more and more research depending on heavy duty ICT capabilities, it's unreasonable to expect researchers to develop and maintain the necessary skills to use all these systems.

Instead, the grid aims to present the researcher with a reasonably uniform interface, one that's well documented, easy to learn and hopefully static. When HPC (high performance computing) or Data systems change, it's up to the operators of that equipment to make sure they connect the interface that the end use expects to the new system.
As they say, "it just works" !

Grid computing offers the possibility to effectively use computing resources country wide.
