The function of a network architect

The function of a network architect is characterized by their responsibilities, which can vary, depending on the specific organization and the size and complexity of their network. However, some common functions/responsibilities of a network architect might include the following:

  • Designing and planning the overall architecture of an organization’s network, including its physical and logical layout
  • Selecting and configuring the hardware and software components that make up the network, such as switches, routers, protocols, and firewall appliances
  • Implementing and maintaining network security measures to protect against external threats and unauthorized access
  • Ensuring the network is scalable, agile, flexible, and able to handle growing demands from business units
  • Monitoring the performance of the network and identifying and troubleshooting any issues that arise
  • Developing and implementing policies and procedures for the use of the network
  • Collaborating with other IT professionals, such as system administrators and application developers, to support the overall IT infrastructure of the organization, and other architects to express opinions about design concerns, constraints, and success
  • Articulating business needs to the leadership
  • Managing vendor relationships and working with external contractors or service providers as needed
  • Staying up to date with the latest technologies and trends in networking and evaluating their potential impact on the organization’s network

A network architect may also be responsible for designing and implementing specific subsystems within a network, such as the data center, the campus network, the metro network, and other private network systems.

In most cases, these responsibilities are completed standalone, meaning without validation or approval from other IT architects. Generally speaking, activities, concerns, or anything similar are brought up during a stand-up or regularly scheduled IT meeting.

In summary, a network architect is responsible for the overall design, implementation, and maintenance of an organization’s computer networks. They play a key role in ensuring that a network is reliable, secure, and able to support the needs of an organization.
