Good day! You´re taking the right path here, if you are intrested in certifying, good choice! I have the experience, that without certifiation your chances to ged a decent job drops heavily. Another factor is your work experience. Building your own hardware
and installing Windows is nothing, sorry for telling you the truth.
Maybe the easiest way is to get MCSA certification with Windows 10. Another, harder way is to get around Server MCSA. Cloud knowledge and services will be asked in a feature for sure, if you´re up to it :)
ps. I wouldn´t bother to go through W7/8 or W2012 server paths. I would wait for new certs to be available.
