V3 Failed AWS CLI S3 Push EC2 Relaunch with existing Keypair

In this video, we create an application but in wrong region. Also, EC2 instance created in earlier video V2 was in wrong region. Due to the same, AWS CLI push to S3 bucket keeps failing. Hence, EC2 instance is terminated and recreated in correct region. Then this EC2 instance is launched with existing keypair.
