1 Minimal deployment scenario
2 Other possible configurations

A gCube infrastructure is a set of working nodes (so-called gHNs, gCube Hosting Nodes) glued by the gCube enabling services and able to host gCube services in a cooperative way.

Minimal deployment scenario

In this section, we report the steps to setup a gCube infrastructure:

  1. decide the scope configuration, i.e. the name of the infrastructure
  2. identify a set of machines to turn on as gHNs (their number may vary depending on the Infrastructure needs)
  3. prepare a Service Map file for the infrastructure
  4. install the infrastructure enabling services:
    1. identify 3 machines to dedicate to the Infrastructure Enabling Services
    2. install gCore in the 3 machines and copy the two Service Map files under the $GLOBUS_LOCATION/config folder
    3. configure the first gHN to join to the infrastructure scope and
      • deploy and configure an IS-Collector instance and configure it to join the infrastructure scope
    4. configure the second gHN as ROOT and to join to the infrastructure scope and
      • deploy and configure an IS-Registry instance and configure it to join the infrastructure scope
      • deploy and configure an IS-Notifier instance and configure it to join the infrastructure scope
    5. configure the third gHN to join it to the infrastructure scope and
    6. start the 3 containers following the order of the deployments and verify that they work properly

Other possible configurations

Alternative configurations can improve the infrastructure performances. In particular:

  • the IS-Notifier can be hosted on a different gHN with respect to the IS-Registry service
  • the Software Gateway can be hosted on a different gHN with respect to the Resource Management services
  • multiple Virtual Organizations can be defined and deployed

The 'optimal' configuration mainly depends on the number of available gHNs and on the expected exploitation of the infrastructure. The more gHNs join the infrastructure the better distribution of resources and services across them is doable.
