Microservices are (a form of) SOA; but SOA does not necessarily mean microservices. The term "microservices" is not as much bad as misunderstood (which, in a way, means that it is bad): it is commonly believed that it implies each service to be "micro" in the size of the codebase. In fact the "micro" refers to the responsibilities/functionalities a service is supposed to provide. Of course, that is more difficult to measure, as the service boundaries are often not obvious.
