The cloud services sector is growing rapidly, particularly in the public cloud space. Market analyst IDC estimates that global spending on public cloud services will top $47 billion this year and more than double by 2017 to reach $107 billion. The analyst attributes this growth in part to a shift in focus from savings to innovation: The first wave of cloud adoption was driven by end users’ need to reduce costs and increase efficiency, whereas the next wave will focus on leveraging cloud services to expand company offerings and improve competitive positions. As the market is shaping up, both end-user companies and cloud service resellers are poised to be beneficiaries of a growing cloud services market.
