Loaded microservice applications for doing different kinds of POC. This is a sample Employee System which is designed to understand the microservices nature and behavior.
The purpose of creating this application is to provide an individual, a holistic idea of microservice architecture, it's working, and its setup.
- Please work in a group
- If we are remote, we have break out rooms!
- We will be running a lot of instances
- Dev-ops is maddening
- We will let a fun service decide your teamname: http://creativityforyou.com/combomaker.html
- Select a leader of your group, they will need a public Github account and generate a token
- The leader should provide a token to the administrator, via virtual chat, slack, or email
