System Configuration

[Milo van der Linden]

Hello Bruce,

There is no standard answer to your question. It all depends on personal 
or business favour, small issues in maintenance and so.

I for instance tried to host a mapset at hostGIS, but due to a strange 
difference in installation with my test server, the datasets turned up 
corrupted on linux. I then decided to purchase dedicated windows 2003 
hosting and set up a mapserver myself with IIS for future use in 
combination with sharpmap ans asp.net.

Our mapserver related business is picking up.
Our mapserver is currently serving about 1000 map requests per day.
Expectation is that this will reach 5000 within the next month. The main 
thing we are currently investigating is setting up tile caching to speed 
up request/response.
My guess is that 5 paying customers will turn a profit on the first 
dedicated server, currently we have 2. 10 customers may be the limit, 
but this is a wild guess.

When we reach 5 paying customers, we will set up the next dedicated 
server. This is the approach we are going to take. Loadbalancing is a 
webserver related matter. This has nothing to do with mapserver 
directly. I have also contacted 52north to set up a secured service for 
mapserver. They have succesfull implementations of WSS and WAS on top of 
WMS.

So the main question to ask is;
- What do you need right now for the actual demand? I wouldn't worry too 
much about growing larger in the future, this issue will solve itself at 
that time, look for load balancing when it looks like it might become an 
issue. Manage your system(s) with care, watch the stats, watch the 
response times per request.

And then decide what to do to keep on track to fullfill demand. This is 
an ongoing process.
