Hi Martin.
Thank you for the reply.  You are right thar for my own rendering jobs I can
use extracts, but my application is a web service so I have no control over
the area requested by the user.
That is why xapi is excellent.  It is only the reliability issue that has me
thinking about my own database server.

I can't give you advice on how big a server should be to keep up with
the whole planet, but going back to your original problem (XAPI not
reliable, you need if for small city extracts) you could download
country extracts for the area you are interested in, and if this is
too big (slow) you could cut even smaller parts of this with Osmosis.

What I am doing myself (not having powerfull server infrastructure at
hand) is additionally extracting features from the planet (cities,
boundaries, rivers, countries, motorways, trunk roads ...) and merge
them with the extract for rendering low zoom tiles.

As long as you are not interested in the details in other countries
(smaller cities and streets) this allows for pleasant rendering IMHO,
"simulating" global coverage.
