At this point, not much is clear about the ultimate impact of cloud computing, However, one thing seems certain: Cloud computing and other emerging technologies will fundamentally change the roles and responsibilities of IT staff. As companies move to cloud computing, they will have a greater need for folks with transitional skills, say experts. Also in demand: systems integration expertise and vendor relationship management skills. Business "super-users" rather than traditional IT staff may handle some of these duties. While many functions will likely remain under IT's purview, staffers should expect to work more closely with their business colleagues.
