Microservice Overview

What is the definition of a microservice?

• A microservice is application that contains all functionalities in a single unit

• A microservice is a software development technique that structures an application as a collection of loosely coupled services, which implement business capabilities.

• A microservice is a software development technique that focuses on tightly coupled services

• A microservice is a standalone application that does not interact with other services

Name one advantage of using microservices architecture.

• Simpler development process

• Limited flexibility

• Improved scalability

• Easier debugging

What is one challenge of implementing microservices?

• Reduced development time and effort

• Decreased scalability due to increased network communication

• Managing increased complexity of distributed systems

• Simplified monitoring and debugging processes

Explain the architecture of a microservice.

• The architecture of a microservice consists of multiple small services, each running in its process and communicating with lightweight mechanisms like HTTP or messaging queues. These services are organized around business capabilities and can be deployed independently. They are built and maintained by small teams, promoting flexibility, scalability, and resilience.

• The architecture of a microservice involves a single monolithic application handling all functionalities

• Microservices are designed to communicate with each other using complex and heavy protocols

• Microservices are always deployed together as a single unit

How do microservices communicate with each other?

• Using telepathy

• Through protocols like HTTP/REST, messaging queues, or gRPC.

• Via smoke signals

• Through carrier pigeons

What is the main goal of microservices architecture?

• To break down large, monolithic applications into smaller, independent services

• To increase the complexity of the system

• To combine all functionalities into a single, large application

• To limit scalability and flexibility

How do microservices help in scaling applications?

• Microservices make scaling harder by centralizing all services

• Microservices help in scaling applications by breaking down the application into smaller, independent services that can be deployed, managed, and scaled independently.

• Microservices hinder scaling by introducing unnecessary complexity

• Microservices limit scalability due to increased communication overhead

What is the difference between monolithic and microservices architecture?

• Monolithic architecture is easier to maintain than microservices architecture.

• Monolithic architecture is more scalable than microservices architecture.

• Monolithic architecture involves using only one programming language, while microservices architecture allows for multiple languages.

• Monolithic architecture involves building the entire application as a single unit, while microservices architecture breaks down the application into smaller, independent services that communicate with each other.

How do microservices contribute to faster development cycles?

• Microservices introduce unnecessary complexity, causing delays in the development process.

• Microservices hinder collaboration among developers, leading to slower development cycles.

• Microservices enable parallel development and deployment of independent services, speeding up the overall development process.

• Microservices require extensive manual testing, which slows down the development timeline.

What are the key principles of microservices architecture?

• Inflexibility

• Multiple Responsibility

• Centralization

• Decentralization, Single Responsibility, Scalability, Resilience, Flexibility, Composable Services
