Hi Alexander,
Yes, the Virtuoso EC2 AMIs are fully functional as they use Virtuoso
commercial edition components.
The costs of hosting such a service depends on data transfer rates ultimately
as this is a continuous charge subscribers will incur as detailed in the AWS
usage documentation. Initial cost of setting up and getting up and running is
low which is the valued added of the "DaaS" services cloud computing seeks to
provide, so you would expect it to be cheaper than buying commercial licenses
and hosting this yourself initially. The key is to work out the long term costs
for hosting such a service based on predicted data transfer rates and
associated costs for the Instance type being hosted, as longer term it could
equally become more costly if you have high data transfer rates and are not
recovering the costs from the service you are actually providing in the cloud.
I presume you have read the "what' and 'why" sections of the Virtuoso EC2 AMI
documentation at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtuosoEC2AMI
So ultimately the options are their, open-source, commercial, cloud and you
chose which one it is felt best suits your needs ...
Best Regards
Hugh Williams
