Cloud build is a service where you upload your project to one of Unity's servers and the game is being built there - not on your own machine. You can work on while the project is being computed.
Hi @leegod - yeah, @the_motionblur is correct: You use Unity Cloud Build so that you don't have to build your game manually inside the Editor. It gets automatically built for you every time to save changes to your code repository. In addition to freeing you up from waiting for builds to finish on your local computer, it also adds benefits like: archiving all your old builds in the cloud anyone on your team always has access to the latest and greatest build we also do the "TestFlight" piece, you can install your builds on your devices without pushing them to another service Let us know what you think!
