Google has announced 30 full-time jobs and 200 temporary jobs as part of a €75m investment in a new data centre in Dublin
The data centre will be located in west Dublin and 200 people will be employed in its construction.
It should take 12-15 months to build.
30 permanent jobs will be created to run the centre.
Google said Ireland's cool climate means outside air can be used to cool the computers instead of air conditioning units.
Announcing the jobs this morning, Minister for Jobs, Enterprise and Innovation Richard Bruton said the data centre would be a powerhouse of Google's expansion.
He said it ensured Ireland is relevant to the company's development.
100 new jobs for Tralee
Elsewhere, 100 new jobs are to be created by a financial services information technology company, which is setting up in Tralee, Co Kerry.
The software development business is part of a Japanese banking corporation, JRI America, which is winding down its software development business at Bangalore in India and re-establishing it in Co Kerry.
The 100 positions will be created over the next five years in Kerry Technology Park.
Recruitment is under way already for a number of positions.
IDA chief Barry O'Leary said: "This is a very significant investment in Ireland by a major Japanese bank which will create a substantial number of highly skilled positions".
