There are zero reasons to limit yourself to 1GB of RAM. By paying $20 instead of $5 you can get at least 8gb of RAM. You can use it for caches or a database that supports concurrent writes. The $15 difference won’t make any financial difference if you are trying to run a small business. Thinking about on how to fit everything on a $5 VPS does not help your business.
> There are zero reasons to limit yourself to 1GB of RAM There is a good reason: teaching yourself not to over-engineer, over-provision, or overthink, and instead to focus on generating business value to customers and getting more paying customers. I think it’s what many engineers are keen to overlook behind fun technical details.
This is specious reasoning. You don't prevent anything by adding artificial constraints. To put things in perspective, Hetzner's cheapest vCPU plan comes with 4GB of RAM.
