Best way to setup ownCloud on ec2, use appliance (with 5.x) or start with Core and install 8.x?

I was hoping to get an idea the best, most easily maintained, install of ownCloud on an ec2 instance.

Should I use the appliance and go through the upgrades, 5-->6,6-->7,7-->8?

Should i start with a particular Core install and then add the components? If so, which components or is there a walkthrough to get me up to speed?

Thanks!
