2 The importance of making infrastructures smarter The implications are significant: Today s IT infrastructures are being strained to the breaking point by new technologies and applications. Inability to serve customers Supply chain delays So what should you do to avoid these pitfalls? Compromised security Slower product development Accenture 2014 All Rights Reserved 2

3 Unlocking the power of intelligence A key step to becoming a digital business is the creation of an intelligent infrastructure. It unlocks agility in the organization, allowing the infrastructure to anticipate and adapt to changing business needs. Delivering competitive advantage and, ultimately, high performance. Accenture 2014 All Rights Reserved 3

4 An intelligent infrastructure is designed to: Know when extra capacity is 1 needed, and even predict when 3 that capacity might be required again. Automatically configure unified communications for employees and secure connectivity to the core enterprise. 2 Optimize services by moving applications and processes to different providers across a hybrid IT environment based on cost effectiveness. 4 Sense a problem that arises and even take steps to fix the problem itself.

6 The six capabilities of an intelligent infrastructure 1. Monitors Automates and orchestrates processes and applications, and configures the dynamic infrastructure requirements. Accenture 2014 All Rights Reserved 6

12 Digital revolution is changing client needs and competition. How this impact our intelligent infrastructure? Value of an intelligent infrastructure is now measured not simply in IT capabilities, but in the new business outcomes made possible: Market is driven by OTT that mask the value of the network Network and Infrastructure are perceived as the limiting factor : slow to change, complex, not standard, expensive COMPETITION OTT TELCOS ICT A more flexible, agile business The ability to serve customers more effectively CLIENTS User Experience, Speed ICT Players Unified Comunication, Cloud (IAAS, SAAS) Better support for collaboration INTERNET OF THINGS CONSUMERS SME ENTERPRISES More predictable cost reductions TECHNOLOGY ENABLERS Software Defined Data Center Software Defined Networking NFV Technologies Accenture 2014 All Rights Reserved 12.
