In addition to the use of the OpenStack interface,
the virtual machines can also be spawned using a set of scripts:
after logging into the gateway node via ssh, change the current directory to geograph-scripts
Now, we can spawn a number of frontend nodes...
remember that frontend nodes must have names starting with "farm-"
Afterwards, we can spawn a number of backend nodes...
remember that backend nodes must have names starting with "geo-"
A utility script can be used to ensure that all nodes are ready
when the nodes are ready, we can send the set of configuration files, specific to the current benchmark, to all the nodes
