Gartner – a consulting firm – predicts that global public cloud revenue will grow 21.4% in 2018. This is a reflection of the world waking up to new ways of managing its businesses, running its systems in the cloud, for example.
A bank needs to manage banking operations, Spotify needs to finland mobile database your music and Netflix provides your audiovisual content. All of these companies have their own specific market niches and manage their systems in the cloud.
The advantage of this, besides the cost, is that you only have to worry about your core business. There is no need to create an IT department in your company to manage a data center. You can focus entirely on your business.
