A while back I was working on a project that allowed replication of an instance of Joomla. The reason for this was that I have a couple of sites that are set up as SaaS applications. Rather than use the traditional method of selling access to multiple user accounts on a single site I needed to provide complete anonymity between users. The nature of these apps were that all data is private and for me the best way to manage both the segregation and anonymity was to provide completely separate sites for each user.
I wanted to use a basic site as a template and then replicate it for each user. This meant replicating both the physical files and the database information for each subsequent user.
I had previously used JMS multisites but had found the component to be a bit overly complicated and limiting when used in a commercial capacity as licenses were required for each replication. It also did not do exactly what I required. I did have a look at modifying the code to do what I wanted but in the end my solution was to simply write my own component.
For my setup I required that each instance had it's own subdomain, but that users could log in from the main domain. Each instance was also created from creating a subscription on the main domain....
