Spending on cloud computing services is growing faster then previously expected, with software-as-a-service (SaaS) and infrastructure-as-a-service (IaaS) two of the most rapidly expanding segments.
Worldwide public cloud services revenues are expected to grow 18.5 per cent in 2017 to a total $260bn, up from $219.6bn last year, according to Gartner.
While that’s still a small element of total worldwide IT spending — which stands somewhere around $3.5tn — it’s a significant number when compared to worldwide enterprise software spending and is expected to reach $351bn.
