Other requirements The target machine has to be connected to the Internet during the installation. If it is offline, you will have to download some additional software manually, in accordance with the installer prompts.

Scaling guidelines

The exact calculation of necessary hardware requires multiple parameters such as data volume and use patterns. However, the general guidelines could be defined as following:

  • If the number of concurrent users is less than 10 and the data update frequency is one per day or less, a single server should be sufficient.
  • For more users or more frequent data updates, a separate server for DBMS is recommended.
  • For the fault-tolerant environment, use two identical servers and any standard load balancer.
