Should a Microservice call another Microservice?
I would generally advise against having microservices do synchronous communication with each other, the big issue is coupling, it means the services are now coupled to each other, if one of them fails the second is now fully or partially disfunctional..
Can Microservices call each other?
Another communication pattern we can leverage in a microservice architecture is message-based communication. Unlike HTTP communication, the services involved do not directly communicate with each other. Instead, the services push messages to a message broker that other services subscribe to.
Can a Microservice have multiple APIs?
While many APIs are created for third parties to make use of — so-called public APIs — the increasing popularity of a microservice architecture has led to the creation of more and more private APIs. In this case, the APIs act as a lightweight solution for individual microservices to communicate with one another.
How do you communicate between two Microservices?
There are two basic messaging patterns that microservices can use to communicate with other microservices.Synchronous communication. In this pattern, a service calls an API that another service exposes, using a protocol such as HTTP or gRPC. … Asynchronous message passing.
How many endpoints should a Microservice have?
The number of endpoints is not really a decision point. In some cases, there may be only one endpoint, whereas in some other cases, there could be more than one endpoint in a microservice. For instance, consider a sensor data service, which collects sensor information, and has two logical endpoints–create and read.
What is the difference between REST API and Microservices?
Microservices: The individual services and functions – or building blocks – that form a larger microservices-based application. RESTful APIs: The rules, routines, commands, and protocols – or the glue – that integrates the individual microservices, so they function as a single application.
