About the Test

This test evaluates the candidate’s ability to build software systems with well-defined interfaces and give quality results.

Microservices also known as microservice architecture, is an architectural style that structures an application as a collection of highly maintainable and testable services, Loosely coupled, Independently deployable, Organized around business capabilities, and Owned by a small team. They enable the rapid, frequent, and reliable delivery of large, complex applications. Microservices also enable an organization to evolve its technology stack.

Microservices is an architecture style that involves building and deploying software applications as a collection of small, independent services that communicate with each other over well-defined APIs. The main goal of Microservices is to provide a flexible and scalable architecture for building and deploying software applications.

In a Microservices architecture, a software application is decomposed into more minor, independent services that can be developed, deployed, and scaled independently. Each service is responsible for a specific functionality or feature of the overall application and communicates with other services using APIs.

1

Microservices

Microservices is an architecture style that involves building and deploying software applications as a collection of small, independent services that communicate with each other over well-defined APIs. The main goal of Microservices is to provide a flexible and scalable architecture for building and deploying software applications.

2

Scalability and performance

Scalability and performance are key considerations in the design and implementation of Microservices applications. Microservices are designed to be independently deployable and scalable, which means that they can be managed and scaled separately from the rest of the application. This allows developers to optimize the performance and scalability of individual services as needed.

3

Integration and communication

Integration and communication are essential aspects of Microservices architecture. Microservices rely on APIs to communicate with each other and exchange data. They are responsible for defining and implementing these APIs in a way that is consistent and easy to use. Microservices may also be responsible for integrating with other tools and services, such as databases, messaging systems, and other external systems.

4

Testing and debugging Microservices

Testing and debugging Microservices is an important aspect of the development and maintenance of Microservices applications. This includes designing and implementing tests for Microservices, troubleshooting issues, and debugging Microservices applications.

The test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.
