Firstly I'm assuming you mean IT Infrastructure and NOT Software development. I personally would either do a degree in "IT for business", or just self teach. The main issue with IT (infrastructure) tends to be that there are different competing standards and tech-stacks, learning about Linux based OS's and servers is very different to Microsoft stuff, there are also the half-way houses like VMware family of technologies. The smartest/laziest/risky way of going about it is usually to find a job you want, look up the requirmenets, and then see if you can get a basic certification in that tech while you're waiting for interviews. Extra points will raise your profile if you can demonstrate a working system setup in either a home lab or using existing cloud infrastructure. If you fail, go to another company which runs the same tech. I for one would rather hire someone who has personally setup a working pfsense site to site VPN rather than someone with 3 years of "theory".
