The Big Bang
In the last century, IBM and Microsoft ruled the world of infrastructure with “physical servers” ranging from huge mainframes to desktop PCs. During that era, each physical server was dedicated to a single workload (except mainframes and few proprietary systems). This lead to unprecedented level of server sprawl (a dedicated server per workload); shooting up the infrastructure costs to unsustainable levels. Time and cost for such servers was huge and the most painful part was that these servers had hardly 15% of CPU utilization – a total wastage of the computing power!As the saying goes – Necessity is the mother of invention!
