Salesforce.com ecosystem recruitment agency Resource in Demand has warned that cloud computing resellers are facing a battle to fill a glut of vacancies in the sector.
Job openings for cloud experts among partners and ISVs are thought to have risen by close to 40% since February 2010.
However, the supply of consultants and developers has virtually dried up over the same period as certified and experienced candidates are snapped up by cloud-hungry firms.
This could lead to a cloud "plateau", said Resource in Demand managing director Lee Durrant.
"This shortage has the potential to halt the momentum that cloud computing has amassed, which could be critical to the growth of this sector," said Durrant, who is advocating increased industry investment in graduate training schemes to alleviate the pressure.
Durrant's warning came at the same time as a new study by EMC and the Centre for Economics and Business Research showed that the total value of cloud computing in the EU could hit over €750bn (£635bn).
The Cloud Dividend Study focused on five key EU economies, including the UK's, and suggested that distribution, retail and hospitality verticals could create over €230bn of value to the industry by 2015.
Banking, financial and business services would also cash-in, and cloud computing would create more than 800,000 public sector jobs across EMEA, they said.
