I believe that 5G can benefit rural and suburban areas that have not enjoyed the same access to wireless as cities. Throughout rural America and the world, there is a lot of aging copper wire that was installed decades ago to support voice transmission. While carriers could replace it with fiber optic cable, from a technical perspective, there is nothing preventing them from replacing it with in-band backhaul. Fixed point-to-point links can be easily accommodated by 5G spectrum allocations to daisy-chain base stations and small cells, and to carry traffic back to the internet and public switch networks for rural areas.

For carriers, 5G presents a ripe opportunity to become more valuable to their Fortune clients by getting deeper into enterprise operations. Consider network slicing, a relatively new concept in which carriers spin up virtual networks using portions of 5G spectrum for particular users or use cases. A carrier could provide this customer with a dedicated virtual network over the 5G spectrum, but with huge bandwidth pipes and the specific millimeter waves that the government is auctioning off, carriers will also be able to parse out spectrum to enterprises on demand.

Moreover, large enterprises—particularly those with campus networks—may soon find millimeter wave products in the marketplace that will enable them to provision connectivity between buildings. Expect these products to quickly become so reliable and easy to install that IT personnel will have control and flexibility as they manage on-site networks. Opportunity awaits. It is a herculean task for future-thinking organizations to comprehend all of the various connected networks, internal boundaries, and interactions with externally connected networks that will be possible moving forward.

Already, most enterprise networks are accessed from multiple locations by employees, vendors, customers, partners, and the general public, by a variety of devices connected through different wireless technologies, mesh networks, and IoT sensors, significantly increasing threat vectors and the enterprise attack surface. Companies should employ new tactics to ensure ubiquitous security throughout the network, its users, and their connected devices. Build it in.

Building security capabilities to meet the requirements of a single network model or protocol will not suffice, leaving organizations vulnerable through other channels. A solution is to build security controls so that they are embedded, inspected, and enforced at the data, device, and user identity levels. Segmenting the network at both a broad level—such as separating security and administrative traffic from general user traffic from critical business application traffic—and on the device and workload-level via micro-segmentation is a key tactic in building a secure, resilient environment.

Zero-trust networks. Organizations can benefit tremendously from implementing a zero-trust architecture, one in which every actor and device must be identified and authenticated, whether they appear to be within your walls or outside your network. A zero-trust approach deploys strategies such as identity and access management, multifactor authentication, encryption, risk scoring, and role-based access controls to enforce strict governance policies that allow users to access the bare minimum of applications and resources necessary to complete their tasks.

Automation of security processes enables an organization to tolerate some amount of cyber risk due to the speed and agility with which it can respond to potential threats. For example, when a traditional network experiences a breach, engineers must identify that a breach has occurred, determine which segment it affects, disconnect it, and figure out how to fix the problem.

If the breach occurs in the cloud or in a software-defined network environment, the fix can be accomplished in just minutes through automation before more damage can be done. Additionally, going forward, AI systems increasingly will be designed to identify breaches in the environment and contain the attack, identify the right fix, and apply it without human intervention.

Network Automation: past, present, and future

The upside to future connectivity is in its speed, agility, and increasingly software-driven nature. As networks become faster and grow more dynamic, their speed, flexibility, and resiliency allow their built-in security mechanisms to identify and address potential threats more quickly than ever before. Your organization will also benefit from relationships with your ecosystem of trusted partners and vendors, who are multiplying your efforts with their own security capabilities and threat identification tools, from the cloud provider with built-in security methods to third-party API providers that are guarding their connection points diligently.

Even as they embrace newer technologies and security protocols, organizations will also need to maintain their legacy infrastructure through existing cyber risk processes. As networks become more varied and complex, deliberate automation and orchestration of security and risk processes become considerably more critical. As the connectivity of tomorrow trend gains momentum, new capabilities to support differentiated, fit-for-purpose networking for devices and applications will become available around the world.

What steps can you take to lay the groundwork for new networking models in your enterprise? Step one could involve scenario planning, in which you create models that consider your business and advanced connectivity together. In the context of our business strategy, where and how can advanced connectivity create a material impact? These capabilities could be a catalyst within an enterprise to accelerate both information technology and operational technology.

Knowledge of these capabilities and potential timing should serve as a key input to shape customer- and internal-facing digital transformation initiatives. Viewed through an alternate lens, digital transformation, enterprise agility, mobility, and cloud technology features such as serverless computing are all dependent on advanced connectivity. However, with advanced capabilities comes higher network complexity in the form of multiple networking protocols, proliferation of devices and device types, and edge computing.

Moreover, these capabilities will likely become available and evolve at different speeds across geographies. For example, sensors in the field and telemetry in applications and on mobile devices will generate increasing volumes of data to be stored, analyzed, and acted upon. Enterprise architecture must consider the impact of distributed computing—between devices, edge, cloud, and data centers and where, how, and when advanced connectivity will be deployed. As you develop strategies for connectivity and cloud, both should align with the strategic goals set forth in your digital transformation agenda.

How will cloud and connectivity help your enterprise operate more efficiently? How can the ability to deliver and process enormous volumes of data where and when they are needed help your enterprise to more effectively engage customers, business partners, or your global operations? Which specific networking and cloud capabilities, deployed in tandem and managed similarly, might support new product and service offerings?

As the trend gains momentum, user expectations of networking capabilities and performance will rise. Vendors will want to recoup their significant capital investments in new products and services. Competition will likely put downward pressure on prices as technologies become more widely available. Prices may be dynamic for some time, requiring enterprises to continually balance user and system demand for advanced connectivity with cost and business value.

The likelihood is that CIOs will need to factor ongoing change into their networking strategy for the next several years. Advanced connectivity can significantly raise the bar on automation. Depending on how far along you are on this path, you may need to make organizational changes to support new operational realities.

Likewise, as you adopt configurable networks deployed with SDN and NFV, your connectivity service provider landscape may take on a different profile. Of course, this will depend on which capabilities you source, from where you source them, and how you integrate them into your infrastructure. The connectivity of tomorrow trend represents a necessary and much-anticipated transformation in the way organizations move business-critical data from where it is generated to where it is needed.

Across industries, this transformation will only accelerate as the total number of networked devices grows exponentially. Increasingly, technology and business leaders are recognizing that when deployed as part of a well-planned connectivity strategy, building blocks such as 5G, satellites, SDN, and NFV can deliver an order-of-magnitude boost in network flexibility, efficiency, and velocity. What will your strategy be for harnessing the connectivity of tomorrow.

Network and computer systems administrators held about , jobs in The largest employers of network and computer systems administrators were as follows:. Although many network and computer systems administrators are employed by firms in the computer systems design and related services industry, they work in a variety of settings.

Some might administer systems and networks for financial firms, and others work in hospitals or local government offices. Network and computer systems administrators work with many types of workers, including other IT workers, such as computer support specialists , database administrators , computer network architects , and computer and information systems managers. Most network and computer systems administrators work full time.

Pervasive Networking

Organizations depend on their computer networks, so administrators may need to work overtime to ensure that the networks are operating properly around the clock. There are degree programs that focus on computer network and system administration. However, because administrators work with computer hardware and equipment, a degree in computer engineering or electrical engineering usually is acceptable as well. Programs in these fields frequently include classes in computer programming, networking, or systems design.

Because network technology is constantly changing, administrators need to keep up with the latest developments.

Problem-solving skills. Administrators must quickly resolve problems that arise with computer networks. Note: All Occupations includes all occupations in the U. Source: U. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. In May , the median annual wages for network and computer systems administrators in the top industries in which they worked were as follows:.

Bureau of Labor Statistics, Employment Projections program. Growth also is expected as the use of IT in healthcare increases. However, an increase in cloud computing could raise the productivity of network administrators, slowing their growth across many industries. Employment of network administrators in the computer systems design and related services industry is projected to grow 24 percent from to The increasing adoption of cloud services by small and medium-sized businesses that do not have their own dedicated IT departments could increase the demand for network and computer systems administrators within this industry.

Job opportunities should be favorable.
