How to decide new age technological career karakatva like Cloud computing, Network Security, Web Marketing, belonging to which bhava or any formula to find out?

This is really interesting question. I used to observe the charts while reading the horoscopes all the time. I will give few hints about it.

In olden days there is no banking service. Later time it came , One of other astrologer identified Jupiter is karaka for banking. In the same the way have to observe it on multiple charts.

Networking / Pharma – Mars & Venus will play role.

Web Designing / Art / Creative – Moon / Venus / Rahu / Saturn

Programming – Sun / Mars / Jupiter

Data Research / Advanced Technology – Mercury / Saturn / Uranus

Online Accounts – Mars / Mercury / Rahu / Saturn

Like that we can find the connection of the planets in their horoscopes. Hope my identification will be helpful for further findings.
