How does this role differ from Network Engineer?
The roles of Network Architect and Network Engineer are related but distinct, though the terms are sometimes used interchangeably, especially in smaller organizations. Generally, a Network Architect focuses more on the high-level design, planning, and strategic aspects of the network. They determine the overall architecture, select technologies, and ensure the network design aligns with business goals, scalability requirements, and security policies.
A Network Engineer, on the other hand, is typically more involved in the implementation, maintenance, and operational aspects of the network. They take the architect's designs and build out the network, configure devices, troubleshoot issues, monitor performance, and perform upgrades. While architects define "what" and "why," engineers often focus on the "how."
Think of it this way: the architect is like the building architect who designs the blueprint, while the engineer is like the civil or construction engineer who oversees the building process according to that blueprint. However, there can be overlap, and in some environments, a senior network engineer might perform tasks that border on architecture, or an architect might be involved in implementation.
Is age a barrier to entering this field?
Age, in itself, should not be a barrier to entering the field of network architecture or IT in general. What matters most are your skills, knowledge, experience, and willingness to learn and adapt.
