Here is a quote from a recent GigaOm post:
Enterprises spend $270 billion on software every year, yet some can’t even calculate the number of employees in their organizations. Shocking? Well, such was the problem for Chiquita before they moved to Workday. But rudimentary challenges like this plague every enterprise in the world, and every individual within those enterprises. When we need to derive anything beyond the basics from our enterprise software, most corporations are out of luck.
This problem is only getting worse. With 1.8 trillion gigabytes of information projected to be generated and stored this year alone, our enterprise technology is on a collision course to become utterly useless if something doesn’t fundamentally change. The data being created is obnoxiously large, with IDC citing that “by 2020, IT departments worldwide will need to administer 10 times the number of servers–both virtual and physical–50 times the amount of data, and 75 times more files.” Our software, infrastructure, and organizations are ill-prepared to manage this scale of data creation, let alone generate anything meaningful or useful with this amount of content being created and shared.
The way I see it, if you want any job security at all, IT is an excellent industry to work for. Of course, only if you are agile enough to keep up with all the changes and developments.
