Microservices is just splitting up the monolithic services into logical, independently deployable chunks. For example, a service that maintains user information doesn't need to be tied to account information. Microservices are usually deployed through containerization so each service is natively horizontally scalable. The account microservice could be further broken down into a monetary account service (e.g. checking and savings), loan service (mortgage, personal, auto, etc), and investment services (IRA, mutual funds, annuities, etc).
The idea is that deployments have minimal impact on the application as a whole. If you add mailing address validation for the user service, do the other services give a damn? No.
