Network administrators, like their system counterparts, are also in the operations and support side of an organization. Network admins don’t typically get involved directly with user or customers, but work closely with sysadmins and other engineers. This role’s main focus is on the network components of the technology and software infrastructure. It is unlikely to see network admins in an organization that has a cloud platform setup, since their main responsibility is to make sure that hardware is set up correctly and that important systems have enough bandwidth and redundancy to serve requests quickly. In other words, this role involves understanding and setting up hardware and the topology of how that hardware is connected. In the cloud, all of that hardware is obscured, which is why you don’t see this role at cloud-based companies. This role also has some certifications for different types of hardware, like configuring routers and switches, but many of these are not required since most network administrators don’t specialize in one type of networking technology. In smaller organizations, this role can also encompass sysadmin responsibilities, like setting up and maintaining printers, firewalls, WANs, IP phones, and mobile networks.
