Create pre-configured images

For faster deployment, you may want to start already pre-configured instances.

AWS

From EC2 Management Console : select the instance you wish to use as a template and click on Actions -> Image -> Create Image.
It creates an AMI in the geographic zone where the former instance was launched.
To use this new image on another geographic zone: in AMIs, select the image, then click on Copy AMI -> Select the zone.

You can now create new instances with this image (See Getting started with AWS).

GCP

In Compute Engine, go to Snapshots and create a snapshot from the instance configured. To create a new instance from this instance, go to Create instance in Compute Engine and select the snapshot as the boot disk image (See Getting started ith GCP).
