IT seems to be a lucrative career option offering of high-paying jobs. However, it's an ever-changing job market. One day a skill is hot and the next it's not.
Job site Dice.com recently published its 2015 Salary Survey, which named the highest-paying tech skills. Of course, skills alone won't always lead to a high salary. Work experience counts, too.
So, here are 30 high-paying tech skills as per the survey.
1. No. 1: PaaS ($130,081)
PaaS or "Platform as a Service" is a type of cloud computing technology. It hosts everything that a developer needs to write an app. These apps once written, would live on PaaS cloud.
