Resizing of a VM which is EBS backed supported
Resizin EBS backed instance can been done however a new public IP assigned, Elastic IP preserved. A store backed VM requires creation of an Amazon Machine Image AMI which can be re-instantiated with a different instance size. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-resize.html

VM Live Migration
Details
|
Recovery processes not clearly defined. SLA for recovery defined (in hrs)
|
If a host fails and the EC2 instance uses EBS, it is possible to start the EC2 instance on another host manually or automatically with monitoring and scripting; if an EC2 instance is installed on instance store and de host fails, the EC2 instance is lost
Some work-arounds are: using an auto scaling group, create a script and use Cloudwatch to trigger this script, in case of degraded hardware stop the instance and start it again; it will start on healthy hardware
|
On host failure the vm will be auto migrated to a new host (guest monitor/restart also available)
