Server specification for MapStore

[Magnus Nilsson]

Hi

I´m planning to let our IT department set up a virtual server for MapStore and I am trying to write a specification for them to use. So far, I have:

• 8 GB RAM, 2 cores
• Ubuntu 20.04 LTS
• Java JRE 8
• Tomcat 7
• PostgreSQL + PostGIS
• GeoServer, including a few plugins:
  • authkey
  • WPS
• MapStore

Am I missing something?

Regards,

Magnus

Hi Magnus,

The initial specs seem OK. The amount of memory you'll need depends heavily on the amount of simultaneous users that will call upon services of GeoServer. With regards to Tomcat, we actually use Tomcat 8.5 instead of 7. (not sure why...)

In addition to your mentioned GeoServer modules/extensions:

• MultiDim (for timeline)
• Cross-layer filtering (for advanced filtering)
• CSS (for styling)

Kind regards,

LP

Thanks LP,  exactly the kind of input I was looking for. The amount of simultaneous users that will call upon services of GeoServer will initially be rather low, perhaps 1-5, so I might start with 8 GB RAM and add more later down the road.

About Tomcat, it seems that Tomcat 7 (mentioned here) will reach end of life soon, so it seems wise to go for a newer version for a new server.

Dear Magnus,

a few points:

- GeoServer + MapStore Backend + PostgreSQL on the same box are going to compete for the memory as well as for the CPU so you might not experience very good performance. 

-- 2 cores is quite low but that's ok, things might be slow but should not break

-- be especially careful on the Heap memory you set for MapStore and GeoServer as you definitely don't want to start swapping otherwise everything will be too slow. Maybe 1GB MapStore, 1.5GB GeoServer?

-- ideally with all these things on the same machine I'd recommend 4 Cores and 12 GB of RAM

- you are missing some plugins but someone else has already pointed them out

- I'd go for Tomcat 8

Thanks Simone, great pieces of advice. It seems I´d better go for 16 GB RAM and 4 cores directly from start. I intend to use the server as a demo environment and if my colleagues like it, I might add one more server in order to separate MapStore backend from data storage/services, if that is the recommended path.

Magnus
