> ModularIT IS really 4 things:
> - A service architecture based on virtual machines
> - A repository of virtual machine images designed to cooperate and to
> be auto-testing and auto-correcting.
> - A system for fast deployment of service virtual machines
> - A framework for managing and monitoring a large number of ModularIT
> installations
>
> ModularIT IS NOT:
> - A virtualization technology (we use Xen and/or KVM)
> - A Linux distribution (We use mainly CentOS, but also have some VM
> with Ubuntu, and we even have plans for windows servers)
> - "Just" a repository of virtual machines. In ModularIT all service VM
> are designed to interact and use the services provided by other
> virtual machines. For example, the Asterisk VM can lookup the calling
> number in the global phonebook (provided bu the eGW VM) to setup the
> Caller ID
> - A Web tool to simplify service configuration.

> a company and it is managed by that company IT team.
> - ModularIT is oriented to simplify deloying, monitoring and managing
> a large number of services in different companies. It's target users
> are IT companies that manages IT services for other companies. In
> ModularIT, each service machine is autonomous and it does it's own
> testing and self-healing tasks. It only depend on external hosts for
> updates and event notification, but not for service monitoring (unlike
> Nagios+remote plugins), this way if a ModularIT host looses connection
> to the Internet, we won't receive any alerts, but it still tests
> itself and corrects any problem if possible.

> Both projects can complement each other, and I think eBox will make an

> eBox has a much better interface for easy configuration of services.

> Of course! In ModularIT, the virtualization server is a minimal CentOS

> CentOS/RedHat. As a matter of fact, if you have any shared storage
> technology, that would be our recommendation.

> We have also successfully installed ModularIT on high available
> clusters. This way you install cluster services in the dom0, and run
> the virtual machine instances as a cluster service. You can even do
> this without any "real" shared storage, using DRBD to mirror volumes
