Difference Between Microservices and API Based Cloud Services

The difference is in granularity. Most of the older web applications are monolithic. APIs are built to external uses which consume interfaces. Microservices aims to maximize reusability by exposing as many potential APIs as possible – built for both external and internal uses. Difference Between Microservices and API Based Cloud Services Not Always Obvious Without Minimum Theory and Practical Work Experience. Web Service is a way to expose the functionality of an application to other application, without a user interface, as an API over HTTP.

 

What Are the Difference Between Microservices and API Based Cloud Services?

 

The difference is in granularity. The biggest advantage of using a microservice is modularity. Each microservice can be developed independently in any programming language. That way, an organization can have multiple teams, each team for one microservice so that the development takes place in parallel and the project completes more quicker.
A developer would build a non-microservices application architecture by putting the RESTful APIs at the edge, facing clients and external systems. These APIs need documentation on how the clients would make use of them. Internally, the implementers would use some other means of coordinating how the app is built internally. Traditional APIs tend to be bulky and may perform lot of functions. A microservices API usually set to serve one job or a small set of closely related jobs. A typical web (REST)API uses the HTTP protocol between the client and the server, components within a microservice architecture might communicate using other protocol(s) like WAMP, AMQP, JSON-RPC, XML-RPC, SOAP and so on.

The idea of microservices is that internal systems can talk to each other and also using APIs. The way of development reflects the organisational structure in the architecture. This could be taken further to the front-end.

Each microservice can be packed into a Docker container with all it’s internal dependencies and deployed into the Docker environment. Now, in that way we have broken down the application into microservices and deployed each of them as a Docker container. Kubernetes is an open source system for automating the deployment, scaling and management of containerized application, for us in these case a microservice.

That is not the way how a normal, non-microservice application is developed. We can not traditionally develop a WordPress plugin. We definitely may use Ruby, Python, JavaScript within a WordPress plugin. Yes, with time as business developing new needs so the WordPress developers are developing in microservice approach.
