IELTS is managed by Cambridge ESOL (formerly known as UCLES) and the British Council and is a British English exam. Most British universities recognise IELTS scores and prefer candidates to take this test, although they sometimes accept TOEFL scores instead.
TOEFL is an American exam using American English (the computer-based test is becoming more common than the paper-based test). It is recognised for entry to most American universities (not all US universities accept IELTS scores).
