Spring Petclinic Cloud

Abstract

1. Introduction

See the presentation of the Spring Petclinic Framework version

A blog bost introducing the Spring Petclinic Microsevices (french language)

Contine with creating the services and deploying the application's microservices. A sample is available at scripts/deployToCloudFoundry.sh. Note that some of the services' plans may be different in your environment, so please review before executing. For example, you want want to fork the spring-petclinic-cloud-config repository if you want to make changes to the configuration.

2. Objective

Fork of the Spring Cloud Microservices project packaged to be deployed on several Cloud platforms: Kubernetes and Cloud Foundry

This project demonstrates how Java, Docker, Kubernetes can be applied to a real-world Blockchain & Cloud Computing problem.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a CI/CD pipeline with GitHub Actions
• Deploy to a public test network or cloud free tier
• Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
