In case of single git ( AMS or AEM as cloud service) code from multiple
projects can be merged with help of parent project for multitenancy but
main problem starts when you wanted to deploy a single site. Suppose
Parent Project have 3 sites SiteA, SiteB, SiteC. we can commit code for
all of these in single git as a module inside Parent project. But How we
can deploy on Site A sometimes only Site B. People share your thoughts
on it.
