I am succesfully running an Alfresco Community Edition on a reserved EC2 instance.
I have recently noticed an official "Alfresco In The Cloud" in the AWS marketplace, whose pricing is lower than my dedicated EC2 instance. So I am thinking about switching to this solution if the following mandatory features are present:
<ol>
<li>custom model and aspect and full customization trough .amp</li>
<li>use of web quick start</li>
<li>file transfer</li>
<li>backup</li>
</ol>
More in general, in which parts this Amazon SaaS differs from the existing Alfresco in the cloud or an Alfresco Enterprise Edition ?
