As per Adobe doc, All the services are components but not vice versa.
But when i checked in http://localhost:4502/system/console/services
It is showing as 6630 service(s) in total.
and then i checked in http://localhost:4502/system/console/components
It showing Number of installed components: 3374.May I know how come the number of services is greater than the number of installed components?
A component can be exposed through more than 1 service interface.
The reason could be there might be runtime multiple instances of services that increasing counts but not sure.
you can analyse more related to your own services/components.
