International Business Machines Corp. this week quietly laid off employees, continuing a wave of job cuts the company announced in April.

The job cuts come after four straight years of declining revenues as the rise of cloud computing threatens its software and services business.

IBM has said it would restructure its workforce to retool for cloud services and data analysis, and could hire an equal number of new employees by the end of the year.

IBM s last round of layoffs, which affected less than 5,000 employees, came in March.

This week s cuts affected workers in the Research Triangle of North Carolina; New York City; Poughkeepsie, N.Y.; and Boulder, Colo.

Some positions are being moved to places like India and Costa Rica, according to workers affected by this week s cuts.
