Enable multi-az for running ec2 instance

Question

How can i enable multi-az for a running ec2 instace? I know how to do that for RDS as there is option on the aws console. But for ec2 instaces where can I find this?

Answer 1

Contrary to RDS, there is no such option for EC2 instances. They are created in a subnet and if you want multi-az you will need to launch multiple instances in different subnets across the availability zones.
