Every single year, the role of help desk, service desk, and sysadmin work changes—and 2025 is no different. In this video I break down what Level 1, Level 2, and Level 3 IT support actually do, how those responsibilities overlap, and why the exact job can look totally different depending on the company. I also talk about the ITIL-style idea of escalation (Level 1 to Level 2 to Level 3), and why smaller companies often force you to wear “all the hats” while larger companies can box you into a narrow niche like storage-only or networking-only. I walk through the traditional responsibilities: Level 1 handling tickets, basic troubleshooting, Active Directory basics, SLAs, and monitoring/alerts; Level 2 being more hands-on with desktop support, onboarding/offboarding, Intune/M365-style deployments, patching, and deeper troubleshooting; and Level 3 covering servers, virtualization, storage (NAS/SAN), networking, cloud (Azure/AWS), and cybersecurity. Then I get into the big shifts you need to prepare for: cloud continuing to grow, DevOps/DevSecOps becoming more common in medium/large orgs, AI and machine learning changing day-to-day support, data governance becoming more important, and security needing to be “first thought” in everything you deploy.
