ACIDBrain

The ACIDBrain team investigates ways to maintain data consistency in microservices applications. We built prototypes in two popular frameworks, Axon and Eventuate, and tested their usability from an end-user's perspective both quantitatively and qualitatively. This repo contains the source code of both prototypes and tests we ran on them.

• prototype: initial prototype without any data consistency guarantees.
• axon-service: the Axon prototype
• eventuate: the Eventuate prototype
• docs: initial proposal and final report. Also see the Past Milestones for other documents we created throughout the semester.
• test: scripts for load testing the applications. They are written to be used by Artillery and has to be modified manually due to some server-side setup do generate different customer ID and IP addresses each time before we run the whole test suite.
• assets: images and diagrams

Build and run Eventuate final deliverable using Docker compose

• Go to final deliverable folder
  • cd eventuate/final\ deliverable
• Build the application
  • ./gradlew assemble -P eventuateDriver=local
• Set the host IP of docker:
  • export DOCKER_HOST_IP= <your-local-machine-ip>
• Launch application using docker-compose
  • docker-compose -f docker-compose-eventuate-local-mysql.yml up -d

Running Eventuate sample on AWS

• We also deployed Eventuate on AWS for testing purposes, and we do not, unfortunately, host the Axon services simultaneously.
• Eventuate test urls
  • http://18.188.46.123:8081/swagger-ui.html create customer; get customer
  • http://18.188.46.123:8082/swagger-ui.html view customer history order; get order
  • http://18.188.46.123:8083/swagger-ui.html create order;
  • http://18.188.46.123:8084/swagger-ui.html create shipment
• Eventuate curl sample
  • see eventuate/test-eventuate.txt for relevant commands and API format

Build and run Axon final deliverable using Docker compose

• Go to axon-service directory:
  • cd axon-service
• Build: mvn clean install
• Start: docker-compose up -d --build
• Stop: docker-compose down --remove-orphans
