Spring Cloud
We continue our project.

Compulsory (1p)

• Use Micrometer and Spring Boot Actuator in order to expose application metrics.
• Create a counter that will measure how many times the StableMatch algorithm is invoked.
• Create a timer that will measure the response time of the StableMatch algorithm.
• Use SLF4J to log exceptions and informative messages.

Homework (2p)

• Install Prometheus and Grafana.
• Collect the response times of the algorithm with Prometheus, and visualize the data in Grafana.
• Set up alerts in Grafana when memory usage exceeds a threshold.
• Use service discovery in order to allow PrefSchedule to find and invoke StableMatch microservice.
• Create multiple instances of the StableMatch microservice and implement an API Gateway with load balancing.

Advanced (2p)

• Use Spring Cloud Config and HashiCorp Vault in order to manage the services configuration.
• Use Spring Cloud Stream in order to implement the event-based communication between PrefSchedule and StableMatch.
