I will use EB and RDS the way you described in this article to deploy an asp.net core API, and there is a Frontend developer will use it, should I terminate all the instances after every use? and will I lose the data in the database if I terminate the RDS instance? And when I develop a new feature, do I have to repeat the steps? Thank you in advance for your help.
