Computer company Dell is to create 150 additional jobs between Dublin and Limerick in its cloud computing area.

Taoiseach Enda Kenny said the jobs represent 'an important step in making Ireland a centre of excellence' in cloud computing.

He said the move demonstrates Dell's commitment to Ireland and confidence in operations in the country.

The company already employs 2,200 staff in Ireland with 1,000 people based in Limerick in service and support and 1,300 in Cherrywood, Co Dublin, in direct sales and telephone-support operations.

Cloud computing is the practice of using a network of remote servers hosted on the internet to store, manage and process data, rather than a local server or personal computer.

Dell cut 1,900 jobs in its Limerick plant in 2009, as its production unit was moved to Poland.

Fianna Fáil Spokesperson on Enterprise, Jobs and Innovation and Limerick TD Willie O'Dea has welcomed the announcement by Dell.

Mr O'Dea said: 'In light of the difficulties that have previously beset the operation at Dell, particularly in the Limerick, I am delighted by this announcement which is very significant for Limerick and for Ireland.'

Elsewhere, 20 new jobs are to be created at Kerry-based services company FEXCO, after it won a Government contract to provide Certificates of Irish Heritage to people of Irish descent around the world.

The certificates are expected to be available to applicants in autumn.

The Department of Foreign Affairs is to announce further details of the scheme at a later date.

Meanwhile, Irish energy technology company OpenHydro plans to add 20 new jobs over the next 12-18 months, mainly for engineers.

The company designs and manufactures marine turbines for generating wave energy.

It said it plans to increase production to meet increased worldwide demand for its technology.

OpenHydro currently employs around 50 full-time employees, mostly at its technical centre in Greencore, Co Louth.
