Edinburgh kept themselves within touching distance through tries from Phil Godman, Tom Brown and Greig Laidlaw, his off the bench, but they struggled to find more.
And forwards coach Foley insisted the victory, Munster's sixth in the RaboDirect PRO12 table this season which puts them third, was near-perfect from start to finish.
"Having made 13 changes from the last league game, to produce a display like that against a quality side, you have to be happy," said Foley.
"In any level of this game, you have to have a dominant scrum if you hope to achieve anything. That's the way it is and always has been.
"And our scrum went very well and reflects the hard work that has been put in by the players themselves and the other thing is the overall effort, great attitude and great work rate.
"We worked hard in the week leading up to the game, training was good and I think we saw the results of that where it counts - out there on the pitch."
