MicroCafe / mono2micro

Mono2Micro

Tools to migrate a monolith to a microservices architecture, focusing on microservices identification, where the set of identified microservices minimizes the number of system transactions (microservices) associated with a business transaction, aiming to control introduction of relaxed consistency in the system.

Currently implemented for Spring-Boot monoliths that use FenixFramework and Spring Data ORMs.

Pre-Requisites

• java 8+ (java --version)
• nodejs 10+ (node --version)
• npm 6+ (npm --version)

Run manually

To run the collectors:

cd collectors/
see README.md for each collector

Due to a limitation in SpringBoot documented in spring-projects/spring-boot#2895, .jar files cannot be generated with more than 655535 total files inside. Due to this, make sure the folder backend/src/main/resources/codebases is empty before building the project.
