The software versions currently used are:
All of them have built it redundancy capabilities.
Sizing is highly dependent on the number of sensors and the polling intervals. Please refer to /wiki/spaces/SIT/pages/26542101 for more information. |
This number should be taken only as a reference, the final sizing would be done during each project.
General assumptions:
Instance | Memory | CPU Cores | Storage |
---|---|---|---|
Small | 8 GB | 2 | 100 GB |
Medium | 16 GB | 4 | 500 GB |
Large | 32 GB | 8 | 2 TB |
For anything larger than 1000 sites we would recommend to separate data-processing server and Web-Interface server (tomcat).
Locations (up to) | Tomcat (data processing) | Tomcat (web interface) | Load Balancer |

3000 | Medium | Medium | Small |
