— The skyrocketing demand for a new generation of cloud-based consumer and business applications is driving the need for next generation of datacenters that must be massively scalable, efficient, agile, reliable and secure. The authors see a parallel between the state of the datacenters today and the evolution of the Intelligent Network (IN) infrastructure in telecommunication. The telecommunications networks have for many years, demonstrated their ability to reliably enable network (voice) services creation, assurance and delivery on a massive scale. Based on an analysis of the Intelligent Networks in telecommunications to identify proven concepts and key lessons that can be applied to enable next generation IT datacenters experience this paper asserts that: • In order to scale cloud services reliably to millions of service developers and billions of end users the next generation cloud computing and datacenter infrastructure will have to follow an evolution similar to the one that...
