I am a senior java developer having 12 yrs of experience . If I take a look at my whole experience, I have gained good understanding on the technology front be it back-end, middle-ware, UI. I honestly feel that when we grow up in the ladder as a technical architect, domain knowledge also plays a vital role. That is the thing I am missing. I am realizing that I did not get any good knowledge in any domain so far.
Currently, I am interested in focusing on storage domain in addition to my java/j2ee skills. Will that add value to my career if I focus on storage domain ? OR Which domain is a better domain for Java architects ? If storage domain is good, can I take the basic SNIA certification?
