Hi Mark,

for the Swiss Open Data Portal (http://opendata.admin.ch), there are two
answers to your question, depending on the government agency:

1. Store all primary data in their existing environment. This is especially
true for agencies that are already used to store huge amounts of data. They
only deliver metadata for the portal, i.e. links to files or APIs in their
2. Store all primary data on Amazon S3. It's very easy to store data there
(either they upload it manually or a harvester reads it from an internal
system and uploads it to S3 for them).

But we also heard from customers that they are obliged to use their own
infrastracture (no matter what).

Regards Stefan
