What the work looks like

  • Patch and upgrade servers and network devices, ideally on a schedule rather than in a panic.
  • Manage user accounts, groups and permissions in Active Directory, Entra ID or LDAP.
  • Monitor uptime, disk, CPU and backup jobs, and respond when alerts fire.
  • Automate repetitive work with Bash, PowerShell or Ansible.
  • Manage virtual machines and, increasingly, cloud resources in AWS, Azure or Google Cloud.
  • Troubleshoot escalated problems the help desk could not solve.
  • Document systems so the next person, or you in six months, can understand them.

How people get in

The BLS lists a bachelor's degree in a computer field as typical, while noting some employers accept a postsecondary certificate or associate's degree. In practice many working admins came up through help desk and desktop support rather than a degree.

The classic route is one to two years in IT support, then a junior or associate administrator role, often at a managed service provider or a school district where you see many systems quickly. A home lab with a few Linux servers, a hypervisor and some automation is a strong talking point in interviews.

Employers often want certification in the products they run. Linux credentials (Linux+, LFCS, RHCSA) and a cloud administrator certification are common choices; for network-heavy roles, a CCNA helps.

Skills employers ask for

  • Linux shell
  • Windows Server and Active Directory
  • Bash and PowerShell scripting
  • Networking (DNS, DHCP, TCP/IP)
  • Virtualization (VMware, Hyper-V, Proxmox)
  • Ansible or other configuration management
  • Backup and recovery
  • Monitoring tools (Prometheus, Zabbix or similar)
  • Cloud basics (AWS, Azure or GCP)
  • Git
  • Kubernetes basics

Outlook to 2035

The BLS projects a 4% decline from 2025 to 2035, but still about 13,400 openings a year from retirements and job changes. Cloud services and automation are absorbing much of the routine server work. The skills are not going away so much as being renamed: admins who learn cloud, infrastructure as code and automation tend to move into DevOps, site reliability or cloud engineering roles.
