Nodejs Website Deployment on Beanstalk

Question

What are the best instances to use if I am deploying a node.js web application within Elastic Beanstalk via EC2 and linking it with an RDS SQL Server instance for storage? I am looking to host this application 24/7 and hopefully gain some user traffic over the first months but don't expect much. I am trying to get a cost estimate and would like to know what instance types I should use for both.

Hello.

If you are considering production operation and are unsure of the amount of load that will occur, why not choose an M-based instance type?  
M-type instance types are highly versatile, so I think you should start with an M-type instance type first and then change to another instance type depending on the load etc.

If the load is small or medium-sized and there is almost no load, I think the T-type instance type is fine.  
However, with T-series instance types, once the CPU burst credits are consumed, the performance will drop to the baseline throughput, which may affect application operation in some cases.

RDS also has M-based instance types.
