When you’re playing with all your cool LEGO Brick toys, you need some way of making sure you always have the right Lego pieces at the right time. It wouldn’t do for you to have everything you need to build a Lego race car handy, but not be able to find the wheels for it! And, if you have all the right pieces, but don’t put them together in the right order, you might end up with something that doesn’t look like a car! In IT, orchestration is the name for the rules used to automatically put all those pieces together in the right order, and always keep them working well for as long as you want to play. And when you’re done playing, orchestration makes sure they’re all returned to the right place so you (or your friends) are ready to play the next time.
