Proof-of-Concept (PoC) application that calls 2 other services.
For example for "Hello world!" this app would be the one providing calling 2 services to get "Hello" and "world", and it would add the "!" at the end.
The purpose of this application is to be used for microservices tech demos and example implementations of tools.
It is in no way, shape, or form a reference for best practices, a good example, or a comprehensive anything. It is a minimal skeleton app with simple logic that can easily be extended.
For more complex demos see:
- Google Cloud Platform's microservices-demo
- Microsoft's eShopOnContainers
- Weaveworks' and Container Solutions' Sock Shop
- Istio's BookInfo
- Kubernetes' Guestbook
- The open-source, multi-language medium.com clones
This repository is configured with support for GitPod for easy development.
