SystemDesign-Microservices

Question 1

What is the definition of microservices in the context of this course?

Answer 1

Microservices are independently deployable modules that make up a larger system. For example

Question 2

What’s the advantage of implementing microservices?

Answer 2

The independent deployment of microservices allows changes in individual modules without affecting the entire application. This speeds up deployment and reduces necessary tests.

Question 3

What’s a deployment monolith?

Answer 3

A system that lacks microservices and can only be deployed as a whole. Changes to one module require deploying the entire application.

Question 4

Does the size of a microservice matter according to the definition?

Answer 4

No

Question 5

What does the chapter on microservices discuss?

Answer 5

It covers the advantages and disadvantages of microservices

Question 6

What is the key technical requirement for microservices?

Answer 6

Every microservice must be an independent process. This is achieved by providing each microservice with an independent virtual machine or Docker container.

Question 7

Why is independent deployment a crucial feature of microservices?

Answer 7

It allows changes to individual modules without impacting others

Question 8

What is the main distinction between microservices and a deployment monolith?

Answer 8

Microservices enable individual module updates independently

Question 9

What does the term deployment monolith signify?

Answer 9

It signifies a system that lacks microservices and can only be deployed as a whole unit

Question 10

Why isn’t the size of a microservice a part of its definition?

Answer 10

While the term suggests small services

Question 11

What are microservices?

Answer 11

Microservices are independently deployable modules used to break down large applications into smaller

Question 12

How do microservices aid in development scalability?

Answer 12

Microservices allow large teams to work independently on smaller units of a project

Question 13

What problem do microservices address with legacy systems?

Answer 13

Microservices help in working with legacy systems by allowing new microservices to replace parts of the old system

Question 14

What does sustainable development mean in the context of microservices?

Answer 14

Microservice-based architectures promise systems that remain maintainable even in the long run

Question 15

Why is replaceability important in microservices?

Answer 15

Replaceability allows for the rewriting of a microservice

Question 16

What challenge must be managed for maintainability in microservices?

Answer 16

Dependencies between microservices need to be managed to ensure long-term maintainability and prevent unintended architectural violations.

Question 17

How do microservices ensure maintainability in terms of dependencies?

Answer 17

Microservices have clear boundaries due to their interfaces
