Are EC2 instances replicated?
You can replicate your AWS EC2 instances from any AWS Region to any other AWS Region, or even between accounts. If your primary account credentials were compromised and all your AWS EC2 data was deleted (which takes a few seconds), you could recover immediately by powering on replica instances in a different account.

How many EC2 instances can I create?
EC2 Instances By default, AWS is limited to 20 instances per Region. This includes all instances configured in your AWS account. To increase EC2 limits, request a higher limit by providing information about the new limit and the regions where it should apply.
Which is better backup or replication on EC2?
Although you can back up data to EC2 instances, replication to EC2 is preferred. Getting your applications and servers back up and running using replicas takes less time than using backups. For example, you can replicate databases from on-premises servers or virtual machines to EC2 instances and perform a failover in the event of a disaster.
Where does AWS DMS create a replication instance?

Can a snapshot be used to launch a new EC2 instance?

How can I back up an Amazon EC2 instance?
Creating an Amazon Machine Image (AMI) is another method of backing up your Amazon EC2 instances. AMI is the image that contains an operating system, all configuration settings, and data necessary for the operation of an EC2 instance. By having an AMI, you can create a new EC2 instance based on this AMI.
