Mono-repo vs multi-repo in Microservices - Quick Revision & Key Differences

Recall & Review

beginner

What is a mono-repo in software development?

A mono-repo is a single repository that contains the code for multiple projects or services, allowing centralized management and easier code sharing.

beginner

What is a multi-repo approach?

A multi-repo approach uses separate repositories for different projects or services, enabling independent versioning and deployment.

intermediate

Name one advantage of using a mono-repo.

One advantage is easier code sharing and refactoring across projects since all code is in one place.

intermediate

What is a common challenge when using multi-repos?

Managing dependencies and coordinating changes across multiple repositories can be complex and time-consuming.

advanced

How does a mono-repo affect build and test processes?

Mono-repos can require more complex build and test setups to handle the entire codebase efficiently, often needing tools to run only affected parts.

Which repository strategy centralizes all code in one place?

A Mono-repo

B Multi-repo

C Distributed repo

D Forked repo

Mono-repo means all projects share a single repository.

What is a key benefit of multi-repo over mono-repo?

A Simpler dependency management

B Independent versioning and deployment

C Easier code sharing

D Centralized build system

Multi-repos allow each project to be versioned and deployed independently.

Which challenge is more common in mono-repos?

A Independent deployments

B Coordinating changes across repos

C Hard to share code

D Complex build and test setup

Mono-repos often need complex build tools to handle the large codebase efficiently.

In which approach is managing dependencies across projects usually harder?

A Multi-repo

B Mono-repo

C Single repo

D Centralized repo

Multi-repos require explicit dependency management between separate repositories.

Which repository strategy is better for small teams wanting tight integration?

A Forked repo

B Multi-repo

C Mono-repo

D Distributed repo

Mono-repos help small teams by keeping all code in one place for easier collaboration.

Explain the main differences between mono-repo and multi-repo approaches.

Think about how code is organized and managed in each approach.

Describe challenges teams might face when using a mono-repo for microservices.

Consider what happens when many services live in one repository.
