The momentum behind cloud computing, a paradigm that centres on the provision of elastic "on demand" enterprise technology services and functions either on-premises or over the web, has been growing rapidly over recent years. And for global enterprises across almost all vertical sectors, cloud computing has risen to the top – or very close to the top - of their IT agendas.

Experts from Gartner predict that, within two years, cloud will have reached the significant point when it will account for the majority of new global IT spend. In fact the analyst company predicts that 2016 will be a "defining year" for cloud.

For security-conscious enterprises the initial moves to the cloud were largely built around on-premises private cloud installations. But investment in public cloud is forecast to grow rapidly over coming years. And hybrid clouds that offer the flexibility of mixing public and private cloud models are now emerging as the key focus area for CIOs. Nearly half of large enterprises will have hybrid cloud deployments by the end of 2017, according to Gartner.

In this CIO interview today we are pleased to welcome Alfredo Nulli, CTO of enterprise storage giant EMC to offer his advice and insights on cloud computing and other key trends impacting the IT industry today.
