IT leaders should build a business and technology plan that aligns to business priorities and spans architecture, technology, operations, and talent. Network strategists and network practitioners should identify career and learning pathways that will give them the skill sets needed to lead this network transformation and enhance their value. Essential guidance Top prediction “By 2025, leading-edge netw orking t eams will have intent-based networks operating across domainscampus, branch, WAN, data center, cloud, service provider, and security. Their networks will be able to comprehend business and application requirements and translate them to network and security policies. Agility will be dramatically improved through the networks intelligent automation, and networks will operate with a powerful feedback loop that provides continuous monitoring, assurance, and optimization. The intent-based network will ensure that business services are continuously delivered and protected across the network. These advances will lead to significant benefits for organizations and also for society at large.” John Apostolopoulos, CTO for enterprise networking, Cisco Section summary (continued) Introduction2020 Global Networking Trends Report 6 Introduction: State of networking for the digital age In a series of memos writt en in 1962, J.C.R. Licklider , a dir ect or at the U.S . Department of Defense Advanced Research Projects Agency, proposed an “intergalactic computer network” in which computers around the world would be interconnected to provide quick access to data and programs from anywhere. 5Only a few y ears lat er , in 1965, L eonar d Kleinr ock, Lawr ence R oberts , and Thomas Merrill used telephone lines to connect four computers together, effectively creating the first wide area network as well as the beginnings of the Internet. 6Mor e than 50 y ears lat er , Lickliders original vision r emains the same, as the network continues to connect global consumers of information and services to applications and data sources. Everything else, of course, has changed. Introduction2020 Global Networking Trends Report 7 Todays world, driven by the exponential growth in technology performance, has become increasingly connected, digitized, distributed, and diverse. With every “thing” possessing the power to process data, compute models are poised to become dramatically more distributed and networked. And as devices and users are added to it, the value and importance of the network as measured by Metcalfes law continues to grow exponentially. Digital business continues to fuel networked innovations. IDC estimates there will be 48.9 billion connected devices in use around the world by 2023, 7and the 2018 Cisco Complete VNI Forecast predicts that the average amount of data consumed across a network will be almost 60 GB per personal computer per month. 3The evolving role of the IT network Introduction2020 Global Networking Trends Report 8 Its not surprising that, given this relentless growth, we find that IT teams are reaching a point where the sheer scale and complexity of networks is exceeding their ability to manage and secure them effectively. Whats needed now are new systems that combine technologies such as machine learning, machine reasoning, and automation to simplify operations and augment human decision making. We are now on the threshold of a new era of networking, when IT can break with the traditional ways of building and operating networks and embrace a future powered by technologies that can solve these challenges in vastly new ways. Before we examine the emerging network technology, operations, and talent trends that form the basis for this new network, lets briefly consider the global business and technology trends driving its evolution.

Understanding these trends can help IT leaders better prepare themselves for the increasing expectations that business leaders are assigning to the network. Global trends shaping network demands According to Gartner, b y 2023, o v er 60% of enterprises will deem networking as core to their digital strategies, up from less than 20% t oda y , deeming networking as a strategic enabler. 8 A brief look at some of these global mega trends reveals the demands they will likely place on the network. According to the World Economic Forum, we are now entering a new, digital-driven era of globalization referred to as “Globalization 4.0.” In this era, digital goods and services, enabled by digital capabilities and artificial intelligence, are the leading exports. 9 As the connections between systems, people, processes, locations, and devices get more distributed and complex, the economic value of the network to the organization will increase, while securing and managing the network will become mor e strat egic and mor e difficult. Network impact Globalization More and more businesses are using digital technologies such as analytics, mobility, cloud solutions, and the Internet of Things (IoT) as the foundation for transforming their business. According to the IMD and Cisco Digital Vortex 2019 r eport, 88% of ex ecutiv es believe that digital disruption will have a major or transformative impact on their industries, compar ed with only 27% in 2015. 10 Digital busines s transformation Introduction2020 Global Networking Trends Report 10 The use of automation and robotics in the coming years will continue to surge as companies look to improve quality, workforce productivity, customer satisfaction, and more. Capgemini Research Institute predicts that wide-scale adoption of automation could result in up to $471 billion in cost savings by 2022 across the automotive, retail, utilities, and manufacturing sectors. 11 Because of globalization and digital transformation, todays organizations are dependent on an increasingly complex web As our world grows more interconnected, organizations are being challenged to grow in environmental sustainability. In addition to the standard metrics, organizations will be judged on how well they reduce greenhouse gas emissions, preserve biodiversity and natural resources, and design products to minimize or recycle waste. Network impact Network impact Network impact Network impact The inherent unpredictability of business requires a network that can quickly adjust to evolving requirements to enable new services, processes, and models. Because automation of processes is time sensitive and mission critical, the network needs to ensure that packets are delivered reliably and on time. An agile, resilient, and secure network architecture is paramount for safeguarding employees, customers, and partners and is vital to recovering data and quickly reestablishing services and access. Advanced networks offer the promise of greater efficiencies in virtually all aspects of the business, from energy consumption to resource usage to emissions reduction. Business automation Business and operational resilience Sustainability of technologies, systems, processes, supply chains , and infrastructur e. Effectiv e busines s resilience requires continuously and proactively assessing operational risks, establishing and auditing contingency plans, and administering incident response training. Introduction2020 Global Networking Trends Report 11 Right now a number of emerging trends are dramatically changing the IT landscape. A closer look at some of these key trends reveals the impact they might have on the enterprise network. The evolving application landscape Applications and data, of course, are at the heart of digital business, and how applications are developed, hosted, and consumed is constantly changing to meet new business needs. Here are some of the ways that applications are evolving, and in some ways, reshaping the network: Technology trends driving network evolution Apps and data are leaving the premises: Applications and data are being modularized into microservices and moved to multiple public clouds. In some cases, they are also being distributed to the network edge. And they are increasingly being consumed from multiple software-as-a-service (SaaS) providers. Apps are modular and distributed across environments: Monolithic applications are in many cases dissolving into interconnected microservices that are delivered via a variety of virtual and physical workloads, including containers, across the entire enterprise. According to the Uptime Institute, half of all workloads will be run outside the enterprise data center by 2021, either in cloud and data center infrastructures or at the network edge. 2Apps are being built continuously and rapidly: For applications developed and hosted on-premises, IT has to accelerate its own infrastructure service creation and delivery to meet the needs of applications and users, all while containing operational costs. Apps are migrating from physical to virtual to containers to serverless: The rise of containers is exposing application design and deployment Introduction
