Re: Capacity Planning

1) Per unit time (day or week), how much data will be persisted to the database, number of records and total size of the data.

2) How much of these data will be updated and how frequently in a given time unit (day or week).

3) Will the databases hosted on the server be for OLTP (OnLine Transactional Processing) or OLAP (OnLine Analytical Processing) or a combination of the two.

4) In case of hardware failure or electrical outage or outage due to other factors including human activity, how much loss of data (and time) can be tolerated, see "https://www.postgresql.org/docs/11/backup.html" and "https://www.postgresql.org/docs/11/high-availability.html".

5) The size of the budget for hardware and manpower.
