Microservices communicate using protocols such as http rest but also asynchronously for example using amqp whenever possible especially when propagating updates with integration events.
Microservices architecture example c.
An example of this kind of simple data drive service is the catalog microservice from the eshoponcontainers sample application.
Microservices is a service oriented architecture pattern wherein applications are built as a collection of various smallest independent service units.
The microservice architecture enables the continuous delivery deployment of large complex applications.
See my code freeze 2018 keynote which provides a good introduction to the microservice architecture.
Internal design for simple crud microservices.
Microservices aka microservice architecture is an architectural style that structures an application as a collection of small autonomous services modelled around a business domain.
In a microservice architecture each service is self contained and implements a single business capability.
This type of service implements all its functionality in a single asp net core web api project that includes classes for its data model its business logic and its data.
All microservices in a project get deployed in production at their own pace on premise on the cloud independently living side by side.
Chris richardson has examples of microservices based applications.
It is a software engineering approach that focuses on decomposing an application into single function modules with well defined interfaces.
Each microservice lives independently but on the other hand also all rely on each other.
For example an application might consist of services such as the catalog service ordering service basket service user profile service etc.
With monolithic systems you usually end up throwing more hardware at the problem or purchasing expense and difficult to maintain enterprise software.
It also enables an organization to evolve its technology stack.
There are numerous other examples of companies using the microservice architecture.
With microservices you can scale horizontally with standard solutions like load balancers and messaging.
