A significant percentage of IT systems are cloud-based, according to a recent survey. The cloud is a key enabler for emerging technology, suggests the CompTIA poll, which was conducted last month. Cloud computing was one of four trends respondents expected to feature heavily in IT conversations over the next 12 to 18 months, the survey found. Others were artificial intelligence, the Internet of Things and cybersecurity. Apart from improved CapEx and OpEx, the cloud offers better security, proponents have argued.
