Digitization is absolutely changing the world—you can picture consumers using virtual resources for shopping and ordering cabs; everyone from toddlers on up generally being glued to their smart devices; and all kinds of businesses, political parties, cities, and countries going digital to have an edge on their competition.
You’ve probably read all kinds of business experts predicting that a big chunk of today’s leading businesses will be displaced by competitors disrupting the market with new approaches. Cisco’s own research corroborates this—that number could be as much as 40 percent. The message is clear: digitization is a disrupter. Embrace it, and you have access to unprecedented opportunities possible from a highly interconnected world of real-time information and choice. Ignore it, and the very survival of your business is at risk.
The Need for IT Skills
For those in IT, moving to digitization requires that you adopt rapidly evolving technologies in the areas of software-defined networking (SDN), mobility, enhanced security, and flexible access, while taking full advantage of cloud deployment models. One technology affects others. For example, you can’t deploy cloud and enhanced access without a clear understanding of the security behind it.
In addition, job functions are evolving from device-level, platform-specific configuration to policy-based service deployment, enabled by the abstraction and automation within controller-based architectures.
Cisco DNA—The Architecture for Digitization
It’s probably no surprise to you that digital trends like mobility, Internet of Things (IoT), cloud, and analytics are being driven by an infrastructure that can respond faster to change.
For that reason, Cisco is announcing the Cisco Digital Network Architecture (Cisco DNA), which provides a programmable, virtualized, and software-driven architecture. Cisco DNA provides the infrastructure foundation as you recalibrate your business, operations and technology strategies to embrace digitization.
Your network becomes adaptive and operates at digital speed.
You can mine business data from your network, and monetize it.
Automation drives more productivity for your technical staff.
The network expands your ability to quickly identify security threats.
Cisco DNA and IT Job Roles
Cisco DNA offers IT engineers across multiple disciplines the tools to facilitate the transformation to digitization. Your entire IT team can expand its skills and collectively operate effectively to fully exploit the power of the next generation of technologies.
Developing Digital Services: Application developers and network/cloud/security engineers can take advantage of network-wide deep visibility into user, application and device information exposed through open APIs. Example: Cisco Connected Mobile Experiences (CMX) Cloud services provide customer insight and personalized engagement.
Virtualizing and Automating Network Services: Network/cloud/network programmability engineers and administrators can provision, orchestrate, adapt, and manage with simplicity and scale, taking advantage of Cisco DNA capabilities like operating systems designed with rich, model-driven, programmable APIs, controller-based management, application hosting, and virtualization. Examples: Day zero automation lowers costs by 79 percent with Cisco Plug and Play; branch agility delivers flexibility to run network functions with Enterprise Network Functions Virtualization (NFV); and differentiated application experience is enabled through EasyQoS.
Mitigating Threats with Security Services: Security and network engineers and administrators can leverage the Cisco network as an enforcer solution. This provides continuous security across their routing, switching and wireless infrastructure, including extending security from the client to the cloud. Examples: StealthWatch, Identity Services Engine (ISE), and NetFlow enable the network as a sensor.
