Shortages in trained cloud-computing staff have resulted in around 1.7 million cloud jobs going unfulfilled in 2012.

A study by IDC showed that applicants lacked the requisite skill set including training, certification and relevant experience.

Demand for IT staff with knowledge of cloud-services is expected to grow annually by 26 percent until 2015.

Cushing Anderson, IDC, said: “Cloud-ready jobs are increasing as we head into 2013, but with this increase comes the harsh reality that IT pros around the world are steps behind when it comes to attaining the skills necessary to thrive in the cloud computing industry”.
