Completely recreate an amazon free-tier instance due to having a new key-pair

Question

I launched a free-tier amazon instance ec2 with some key-pair. Then I deleted this key-pair and created a new one. The instance kept running with the first (deleted) key-pair. I wanted to re-create the instance but the only thing what I could do was terminating it. So I have a terminated instance with the deleted key-pair and the new key-pair which is not used.

Ideally, I'd like to go back to square one and create a new instance and use the existing key-pair (or create one more, that doesn't matter). How can I do this?

Answer 1

so, the free tier means, you can have 750 hrs per month of t1.micro type of instances. How you reach this limit is upto you. You can run 1 instance of t1.micro type for 750 hrs per month or running 75 instances of t1.micro type for 10 hrs each per month. Also this free tier dies after you complete 1 year and then you have to pay even for running t1.micro instnaces.

So...

1. Free Tier does not have PostGreSQL RDS included. It does have MySQL, SQL Server and Oracle.
2. So, your only other option remains is to have an EC2 instance of t1.micro type and install configure PostgreSQL on it just the way you would do it on any other server. However, I really doubt the performance of this instance running PostGReSQL on a t1.micro type.
