The only insight we get into the poor state of DR procedures is in some

Big shift towards Cloud environment has started. It is now clear that this
change is similar in magnitude to the shift from mainframe to client-server
computing two decades ago.
Amazon Web Services is the pioneer and market leader in Cloud computing

quite extensive and cover many of the enterprise-class computing needs. APIs
and command line interfaces are available for each service, which makes
scripting and automation achievable. ... (more)
