Hedge 189: Data Center Careers with Carrie Goetz

When network engineers think of a data center, we think of fabrics and routers and switches. There is a lot more to a data center, though—there is power, building construction, environmentals, and a lot of others. What possible jobs are out there in the data center space for people who want to work in IT, but don’t either want to code or build networks? Carrie Goetz, author of Jumpstart Your Career in Data Centers joins Tom Ammon and Russ White to tell us about a few, and about the importance of other careers in the data center.
