3 cheap ways to learn high-tech skills, who's hiring at high wages

High-tech jobs are fast-growing and they command high salaries. However, the sector is also facing labor shortages in Georgia, according to the Bureau of Labor Statistics.

And it's not just tech whizzes who can tap these benefits. According to experts like insurance giant Northwestern Mutual, fairly ordinary employees can ramp up their technical skills without spending lots on tuition. "Add a massive skills gap in tech fields and scarcity of talent to the mix, and you can see why pioneering companies are redefining what it means to be qualified — they need to fill a ton of jobs," NWM explained. "If you're thinking about boosting your skillset (or paycheck) today is a great time to start."

Learn in-demand skills from cloud computing Salesforce.

Computer science degrees from high-ranked schools are always going to be the mainstay for the highest-paying high-tech jobs. "But it's not the exclusionary domain of incredible talent," LinkedIn CEO Jeff Weiner said at the 2017 ASU GSV Summit."We're finding that people with very basic coding skills but [who] have graduated from a coding boot camp...we're looking for folks like that. We're looking for folks with a growth mindset. We're looking for people with the dedication, with the work ethic. We want to give them a shot. And what we're finding is, these people are...incredibly talented, and they need a chance."

And the need for high-tech workers will just keep growing. According to a 2017 IDC white paper sponsored by Salesforce, between now and 2022, the Salesforce cloud computing economy will create 3.3 million jobs total. It will have the most powerful impact on the finance industry. It predicted 585,000 new jobs in the finance sector, accompanied by a predicted $164 billion in new finance revenue. The Salesforce manufacturing economy will increase $159 billion in the same period, adding 638,000 in new jobs.
