Early on, vendors who wanted to compete with AWS would speak to the idea of an “enterprise cloud.” All the US Federal activity that AWS had been up to - including that $600m private cloud for the CIA - seems to nullify most of that.
I think what will be more important is targeting the type of application supported: old school, three tier app that are statefull everywhere, or cloud native, microservices apps that are stateless (shoving statefullness of to caches and databases).
