How can I host my MEAN application in AWS? [on hold]

I am very new to AWS. I am having a MEAN application. But instead of mongoDB we use postgres database. I have to host that application in AWS. I am having very less knowledge on aws. So can somebody please guide me through how can I achieve this from selecting the aws instance and isntalling the postgres DB to hosting the application. The application is very light weight and I am hosting it for demo purppose not as prduction.
