[Geoserver-users] [bulk]: What Should Be the Specification of a Map Server to Serve Around 20 Users Simultaneously

Hi,

There are not really simultaneous users in OGC services because they are stateless. User sends a reques and gets server and then the job is done. Users just being online and ready to do new requests do not cost anything for WMS and WFS servers but only the real requests count.

Do you mean that you may have 50 people browsing your maps or digitizing and sending request while they zoom and pan on the map? If this is the situation then the demands for the server are minimal. With 4 CPU-cores and 16 GB memory with some fast HDDs or better SSD that was specified in the previous mail you should be able to serve hundreds or thousands users but of course it depends on your needs,data, and configuration.

Hello,

in my opinion this needs more specification what you are planning.

For example:

-What kind of data do you want to deliver? Postgis? Raster data? Shape files?

-How many data do you have? 1000 entries? 1.000.000 ?

-How complex is your styling?

-What kind of service do you need? Really wms? Or can you serve tiled maps?

-If you can serve tiled maps how dynamic is your data? Can you preseed the tiles?

-You are talking about 20 Users who are simultaneously using the service. Are they really using it simultaneously in the same seconds? Or do you have 20 users overall?

I would expect that a small server mit max. 4 CPU-cores and 16 GB memory with some fast HDDs or better SSD would be fast enough. But this is really a rule of thumb estimating which can vary enormous to bigger or smaller servers.

Cheers

Stefan

Subject: [bulk]: [Geoserver-users] What Should Be the Specification of a Map Server to Serve Around 20 Users Simultaneously

Dear All,

I’d like to know what should be the (physical) specification of a Web Map Server to server around 20 users simultaneously with good performance.

Anyone please give me advice.

What should be the specification of a Map Server to deliver the maps with good performance If the users increase to 50?

Thank you very much in advance

Best Regards

Hi,

Thank you very much for the suggestion, Stefan, Jukka Rahkonen and Justin.

I’m expecting a around 20-50 users for WMS zooming & panning.
A small number of user will be using WFS.

For the WMS with basic layers, the style is not that complex.
Layers will be a mix of raster and vector (shape file, PostGIS) and the number of layer will increase gradually.

I’ll try with minimal first and see whether it can serve the user request (without overloading the WMS).

Best!
