Database servers depend heavily on memory working set and disk latency, not CPU alone. More RAM does not fix bad queries, and fast NVMe does not replace missing indexes. Measure query and cache behavior before scaling hardware.
It depends on active dataset, connections, cache hit ratio and query profile. Small web databases can run in 4–8 GB, while larger working sets and heavier queries may need 16–32 GB+. Measure database metrics first.
Scaling CPU or memory without knowing the bottleneck can raise cost without solving the issue.
A single VPS is simple for small projects; as the database becomes critical, isolation becomes more valuable.
Lower cost, simple ops
Resource/access isolation
More cost and operations
Query analysis inside the database is still required; these commands inspect host state.

It helps random IO and latency-sensitive workloads, but memory/cache and proper indexing/query design matter just as much.
Usually no. Applications should connect through private networking or localhost.
No. If working set, cache usage and query profile do not need it, extra memory may provide limited benefit.
Share active data size, connections, memory usage and backup target; we can size the DB VPS.
