Amazon MySQL RDS

Question

I'm part of an NGO & we are building a website that uses MySQL as the database. Since we don't have a DBA on the team, we were considering using AWS RDS. I was looking at the 4vCPU with 16Gig option and it costs about 250-300$/month even if I go with the reserved instance RDS. This is outside our budget.
Before I look for other alternatives, I wanted to try the 2vCPU with 8 Gig RAM. We only have about 30 tables in the database and the data volume will be less than 2 Gig. Number of concurrent users will be around 50. The application is not compute intensive.  We are mainly using GET, PUT and POST APIs that read/update the data. Will the 2vCPU/8 Gig RAM option be able to handle this load? I'm not a MySQL DBA and only a developer. Hence I don't know how many vCPUs/RAM will be required to handle this load. 
Any suggestions are appreciated.

Answer

You can definitely try  `2vCPU with 8 Gig RAM` or even smaller. RDS has many built-it metrics and graphs for monitoring, so you can identify if your DB does not have enough resources and in this case, you can easily add more resources

One more option - Aurora Serverless, that can "scale compute to zero" if you don't use the DB
