[clug] Suggestions for hosting a large low-usage database

One of the advantage of "the cloud" is the ability to scale up as
needed. I'd take the smallest EC2 instance you can create and then when
that proves too small: Stop the instance increase the RAM, CPU, and disc
as needed then restart the instance. I know GCP will even let you know
in the console when this is a good idea with " Increase perf." written
next to the VM in the table. Clicking on the link will then get you more
detail such as "This instance has had high CPU utilisation recently.
Consider switching to the machine type: custom (2 vCPUs, 3.75 GB
memory)." I don't know if AWS has such a feature as it's been a while
since I've had to change anything in work's AWS configuration. The point
was that you can simple increase the size as needed with an outage of a
few minutes so don't worry about starting small it will save you dollars.
