EGI FedCloud Users FAQs

How can I get access to the EGI.eu Federated Cloud?

The information is available here.

How can I get the list of the FedCloud sites?

The federated cloud is currently in testbed phase. The list of the testbed FedCloud sites is available here

How can I choose which FedCloud site to use?

FedCloud sites offers their resources voluntary to all the FedCloud user comunities.

To find the better site for your need, it is recommended to send an email to the EGI.eu UCST Team, with a small description of your needs and your field of research.

In a command line environment, using the rOCCI client (a guide on how to install it is available here), you can run the following command

occi --endpoint site_occi_endpoint --action list --resource resource_tpl --auth x509 -X -x proxy_certificate

where site_occi_endpoint is the site OCCI endpoint and proxy_certificate is the path to your VOMS proxy certificate (obtained via the voms-proxy-init commands, see here)

How can I get the list of the OS templates available on a site?

In a command line environment, using the rOCCI client (a guide on how to install it is available here), you can run the following command
