An introduction to the European Grid Infrastructure

EGI Community Forum 2014, 19-23 May
Helsinki, Finland

Summary:
This presentation was part of a session which introduces the concepts of grid and cloud-based distributed computing, the architecture, components and user-facing services of the European Grid Infrastructure (EGI). It consists of a set of tutorials composed of short talks and demonstrations that will introduce to the audience:

+ Main services of the European Grid Infrastructure
+ How to get access to the EGI production system
+ Federated Cloud service from EGI
+High level tools for application development, sharing and access

3. www.egi.eu A dream called … the Grid 3 • Grid computing is a concept which takes distributing computing a step forward • The name ‘Grid’ is chosen by analogy with the electric power grid: ─ Transparent plug-in to obtain computing power without worrying where it comes from ─ Permanent and available everywhere • Grids are computing infrastructures providing seamless access to computing power and data storage all over the globe Taken from a recent intro grid tutorial by NGI_PT
