If you want to provide immediately failover, then you will need to run multiple Amazon EC2 instances. That way, if one instance becomes unresponsive, then the other instance can handle requests.

If you are going to run multiple instances, it actually makes more sense to have both instances responding to requests at all times, since they can handle twice the load. Then, if one instance fails, the remaining instance can still handle the load.

There are a few services that can assist with this...

Elastic Load Balancers can distribute incoming traffic across multiple target instances. It also performs Health Checks and can automatically stop sending traffic to instances that stop responding.

Amazon EC2 Auto Scaling groups can monitor EC2 instances and automatically replace failed instances with new instances. (It terminates the bad instance and then launches a new instance.)
