Issue
I want to add memory to an ec2 micro instance that contains by default 1GB of RAM. Want to make it 2GB. Is it possible? Do I need to create a new instance or can I change an already existent instance?
Solution
EC2 instances have a very specific configuration regarding CPU, RAM, local instance storage, etc.
It is not possible to alter that configuration.
If your application needs more RAM than a micro instance can give you, then you need to move to a different EC2 instance type.
For 2 GB of RAM, you can change your instance to a t2.small instance.
