IT infrastructure has become critical and is very different to what it used to be some time ago. Digital technologies intensify the scale of disruption by bringing in tectonic changes. Emerging technologies and processes such as automation, AI, 5G, IoT, edge and ambient computing, DevOps, and AIOps, are catalysing a new wave of innovation. Having an infrastructure is to become secure, agile, service-oriented, and capable of delivering unified digital experiences to end customers.
