We will be deploying a set of microservices called a social network. The service is composed of two main service, users and friends. The users service stores all the users in its own data store. The friends service stores the user's friends. The events of adding a user/adding a friend are sent to a recommendation service backed by a graph database that is then used to query relationships between users. You can query the graph database with questions, such as give me the common friends of user X and user Y.
In the following section, you will do the following:
- Use Helm to deploy a sample microservice-based application
- Test the service by sending events and watch objects being created and updated
