Open Stack

Hi Mark!

>From what I know, "Cloud Computing" environments, like OpenStack,
Eucalyptus or AWS EC2, differs a lot from "Virtual Data Centers" like
OpenNebula or even pure XenServer, EXSi or Linux KVM...

Here at the Cloud, we have a different approach, when you want to "resize"
your Instance, you'll need to destroy it, and then, recreate it again. That
is why solutions like Puppet or Chef are heavily used within Cloud
Computing environments, automation, automation and more automation...

Your data must/should be hosted within services like "Block Storage /
Cinder" and your application within the Image (hosted at Glance) itself.

Mostly because your Instances is almost disposable, your focus must be at
the images (a.k.a AMI) and on persistent storage (Cinder), not within the
Instance itself, so, when you need to grow, just start a bigger Instance or
add more Instances to your pool...

Your application image (AMI) must be up-to-date, your data is on Cinder and
you can have automation (when you are dealing with basics AMIs like Ubuntu
Cloud and needs to deploy your application using puppet / chef within it)...

Also, would be great to hear from more people about this topic...

Cheers!
Thiago
