The flow of data across an internet-connected computer network is the fuel that powers the engine of modern business. Without a consistently reliable and fast computer network, businesses will lose their competitive advantages and bottom lines will suffer over time. This is why the job of the network architect is so important to the enterprise, regardless of its size or stature.

What does a network architect do?

In general, a network architect is responsible for designing computer networks, including local area networks (LANs), wide area networks (WANs), internet connections, intranets and other data communications systems. People in this position analyze the current network needs of the business or organization and determine how those needs might change in the future. The network architect then develops a plan to meet those future needs.

For the most part, network architects fall into department management roles overseeing teams of network engineers, system administrators, and perhaps application developers. The goal of a network architect is to design efficient, reliable, cost-effective network infrastructures that meet the long-term information technology and business goals of an organization. The trick is to accomplish those long-term goals while also permitting the organization to meet its short-term business goals and financial obligations.

While designing networks may be their primary role, network architects and their teams may also be asked to monitor, test and troubleshoot business networks. In addition to other considerations, network architects will generally be asked to monitor, adapt and adopt network security to meet and subvert ever-changing cybersecurity concerns. This may include replacing outdated hardware and retooling vulnerable software.

What kind of personality makes for a good network architect?

Successful network architects must be able to see the big picture regarding current and future information technology infrastructure, not only for the organization but for the industry and general business environment as well. Individuals fulfilling the job role must be able to produce a documented vision of network infrastructure now and in the future.

Documentation is important because a network architect must be able to present their vision of current and future network needs and goals to C-level management, employees and other stakeholders. They must be able to communicate why their vision is correct, and why those stakeholders should provide the resources necessary to bring that vision into fruition. Those extraordinary communication skills often come with extensive experience as a system administrator or network engineer.

Beyond the technical expertise to envision computer network needs of the future and the communication skills to convince stakeholders to commit resources to that vision, a network architect must also be able to thrive under the pressure of making impactful decisions on a daily basis. As a high-level manager, the network architect will be called upon by engineers and technical staff for guidance and direction. The pressure of making daily decisions is not a working environment everyone can thrive in.

The steps to becoming a network architect

Education requirements for network architects

At the bare minimum, a network architect will have a bachelor’s degree. The area of study will likely be technical such as information technology, computer science, or information systems management. However, bachelor’s degrees with specialization in business administration or other areas may be considered, if accompanied by extensive experience. Additional courses or training in business communication are recommended.

Speaking of experience, because network architect is a high-level management position, long-term experience (5+ years) as a system administrator, network engineer, or network architect is going to be priority for any human resources recruiter. Professional certifications and higher-level degrees will be viewed as a plus, and candidates with those credentials will receive preferential treatment.
