Subject RE: Migrating VMs from AWS to CloudStack
Date Thu, 07 Sep 2017 18:11:51 GMT
Hi Eric,

I must thank you for your detailed advice.  I myself am a python lover and I
use Ansible for automation  and DevOps. The issue here is that this aws
account was being maintained by the customer himself. Now after we designed
and implemented this CloudStack solution for him, the customer has asked us
to do the complete shifting of instances  from AWS to his own CloudStack
that we have setup for him. And that's why here I am to learn from others
experiences and then device the final strategy and jumpstart the actual

Not happening unless your instances on Amazon are Centos or some other
"standard" Linux distribution, not standard Amazon Linux. Amazon Linux is
its own thing and won't run outside the Amazon ecosphere, and Windows
instances on AWS don't react well at all to having their hypervisor yanked
out from under them and a new hypervisor slid under them.

When I did this recently, I instead set up a Puppet server with a clone of
the puppetry that set up my AWS instances (my full puppet configuration tree
was in a git repository so that was not a big deal), modified it to set up
the same software on Centos rather than Amazon Linux (took some slight mods
because the standard OS packages are slightly different between the two),
then set up some fresh instances using a template that had puppet
pre-installed on it and the userdata scripts from my CloudFormation
templates minus the AWS-specific bits (the userdata scripts are responsible
for configuring the instances to connect to the puppet server with the
proper instance type in order to do the final configuration). 

If you are not using a configuration management system like Puppet, Chef, or
Ansible, you're doing things wrong. You've *been* doing things wrong.
Managing a fleet of virtual machines by hand is not the way to do things in
the 21st Century.
