We have deployed a web application on an m5.xlarge EC2 instance and when we try to buy an annual or 3 years reserved license, AWS recommends based on our current usage it is recommended to purchase 54 t2.nano instances instead of the m5.xlarge we have now. It calculates and shows a difference in the overall cost and shows that going with that option is more profitable to us.
The thing I can't understand is what does it mean to buy 54 t2.nano instead of one m5.xlarge? Does it mean we need to host the application in all 54 nano EC2 servers and then put it through an ELB? I am a bit confused here about what to do
