Hi,

Just sharing something I just discovered.

This SAAS apphttp://watchful.li/ that give the ability to upgrade Joomla websites/plugins/... uptime, backup, remote installer,...

Here is also a similar product the will be release for modx

It would be a revolution if concrete5 had a such app. I would pay for such service.

It's way better than having a single core for multiple instance of C5. It's more flexible and better than a cloud solution in my opinion.
