GCore

gCore

The gCube Core Distribution (gCore) is a packaging of the components of the gCube system[1] which are ubiquitously deployed within a gCube infrastructure. The distribution includes:

• the gCore container, a container for the deployment of gCube services and the basic management of their Running Instances (RIs). A running instance of the container listening on a given port identifies a gCube Hosting Node (gHN), the topological unit of a gCube infrastructure;
• the Local Services, a small set of distinguished gCube services which either ensure the correct operation of the gHN or else prove convenient to deploy next to any service which may run on it ;
• the gCube Core Application Framework (gCF), a patterned code base for the development of gCube services and their clients;

gCore builds upon Globus technology and tailors it to the requirements of gCube. The gCore container is a customisation of the container distributed with the Globus Toolkit [2]. Similarly, gCF is a substantial extension of the Java WS Core framework, also distributed with GT4.
