I work for a small business with little IT infrastructure. We want to be able to join all computers throughout the company to a single domain to push group policies and conduct other management functions, however, we have 15 offices with 1-2 employees at each office and 10 at corporate with a total of 36 employees. To me, it doesn't make sense to invest in the infrastructure to setup a domain controller with a firewall at each location.
Based on my research it seems like moving everything to the cloud (Azure) or doing a hybrid approach with our on-premise server would make more sense. Is my thinking correct here? Would there be a cheaper way?
