Day 4/30: Bigger EC2 does not always mean better

Some teams choose the largest server “just in case.”

That is like hiring a 60-seater bus to take two people to work.

It will work. It will also cost more than necessary.

Start with realistic capacity, monitor CPU, memory and traffic, then resize using evidence.

AWS makes increasing capacity easy. Your Finance department would prefer that you do not start with the most expensive option available.

Right-size first. Scale when the data tells you to.
