Microservices Interview Questions
The term 'idempotence' refers to the repeated performance of a task despite the
same outcome.
In other words, it is a situation in which a task is performed
repeatedly with the end result remaining the same.
Usage: When the remote service or data source receives instructions more than
once, Idempotence ensures that it will process each request once.
26. What do you mean by end-to-end microservices testing?
Usually, end-to-end (E2E) microservice testing is an uncoordinated, high-cost
technique that is used to ensure that all components work together for a complete
user journey. Usually, it is done through the user interface, mimicking how it appears
to the user. It also ensures all processes in the workflow are working properly.
27. Explain the term Eureka in Microservices.
Eureka Server, also referred to as Netflix Service Discovery Server, is an application
that keeps track of all client-service applications. As every Microservice registers to
Eureka Server, Eureka Server knows all the client applications running on the
different ports and IP addresses. It generally uses Spring Cloud and is not heavy on
the application development process.
28. Explain the way to implement service discovery in
microservices architecture.
There are many ways to set up service discovery, but Netflix's Eureka is the most
efficient. This is a hassle-free procedure that doesn't add much weight to the
application. It also supports a wide range of web applications. A number of
annotations are provided by Spring Cloud to make its use as simple as possible and
to hide complex concepts.
29. Explain the importance of reports and dashboards in
microservices.
Monitoring a system usually involves the use of reports and dashboards. Using
reports and dashboards for microservices can help you:
