Amazon EC2 AMI’s can now persist.

Amazon EC2 has enhanced the integration between its Elastic Block Store (EBS)

and EC2 instance functionality.

Amazon EC2 instances can now be booted directly from Amazon EBS

volumes, and customers now have much richer control over how block devices

are exposed to their instances.

This allows larger root devices, faster launch times, greater instance

durability, and the ability to repair a mis‐configured instance.

This also enables a number of very desirable features that we have been

waiting for …, such as the ability to stop an instance without terminating

it, and the ability to create an AMI that is based directly on an existing

instance

At this point, the instance will move from the “Stopped” to “Pending” to “Running”

state. Once it is running, you can interact like any other running Amazon EC2

instance.

It is potentially important to note that the public IP address of your instance may

change after it has been stopped and restart. If this is not desired behavior you

can leverage Elastic IPs to create a consistent IP address.

Building an AMI from a running instance … the ability to take a snapshot in

time, save and then restart that snapshot.

One common use case is the desire to make a point‐in‐time copy of the

contents of the root device so that another instance could boot off of that

image. Images are typically created for backup purposes or to make clones

of the existing instance.

Previously, this process on Linux required you to create an image of your

instance on the instance itself and no APIs were available to assist. On

Windows, there was an API that you could call to create an image of the

instance, but had to make another subsequent call to register the AMI.

Now, there is one API for both Linux/UNIX and Windows that allows you to

bundle your AMI backed by Amazon EBS and register it.
