| Rex,
The Wikipedia article says: an application is a computer program designed to help people perform an activity.
While I’d say that is correct, I’m not sure it’s useful. BTW, the discussion on slicing and dicing what is application vs. operating system vs. utility … was entertaining.
What I am looking for is a definition of application in the context of “components are defined as independent microservices that any application can use”. I don’t necessarily need an exhaustive taxonomy but this goes back to old discussions of when is an application offered as a service or when does a service constitute an application.
I’ll take anything that provides some clarity.

The conventional
definition of application software from Wikipedia still works
for me. https://en.wikipedia.org/wiki/Application_software
However, I think you
may be looking for the definition of something in relation to
the conventional definition of application that is like
microservivce is to servivce, e.g. micro application, or
containerized/componentized application. Correct? Rex

Came across this article
and while the focus is really on OSGi, its
discussion of microservices includes the following:
The first model is the microservices model. With this model, components are defined as
independent microservices that any application can use. They
also have stateless behavior so they can be replaced and
scaled as needed. Additionally, they are independent of each
other and of applications that use them, so
deployment/redeployment of a microservice doesn't affect
applications it serves.
and
But microservices might be the biggest revolution in componentization.
A microservice is a logic component deployed in RESTful form,
designed to be accessed through a URL. Microservices easily
address issues of component dependencies and avalanches of
redeployments due to small component changes because
microservices are independent as long as the API call formats
are maintained. Microservices won't change the modularity of
JVM or provide an efficient way of managing
remote-versus-local components, but they could significantly
reduce the burden of component management for distributed
components.
My biggest problem is I have yet to see a good
definition of “application”. Is it just the user interface that
calls microservices under the hood?
Any favorite (attributable) definitions of
application?
