Finally, a boot camp where you’re encouraged to get your head in the clouds…er, the cloud. If you’re trying to establish any kind of cloud-based service, for yourself or a client, Amazon’s Web Services takes away the massive problem of actually having to build a server farm. That simplifies the work of setting up any service or application, and can help save (or make) you a lot more money, but only if you know how to use it. To help get your rear in gear, Udemy is offering the Amazon Web Services Engineer Bootcamp Bundle, a set of four critical courses. Clocking in at 24 hours’ worth of instruction on how to tap the potential of Amazon’s cloud, right now it’s 89% off the usual price — but like a vapor, this deal will disappear before long.
