 * Service should handle autoscaling without disruption or data duplication
 
 ### Service Levels
-* Define three Service Level Objectives (SLOs) for the API service
+* Define five Service Level Objectives (SLOs) for the API service
 * Create a service to periodically evaluate the defined SLOs and report on their status
 * SLO service communication is secure
 
 ### Deployment
-* Create a Helm chart for the API server
+* Create a Helm chart for the API and SLO services
 * Single make target to build and deploy all artifacts and certificates to a Kubernetes cluster
 * Ensure artifacts and services are production ready
-* Evaluate the state of three security invariants
+* Evaluate the state of five security invariants
 * Automatically autoscale API server
-* Make target for automated load test against API server
+* Deploy a zero-trust implementation of Prometheus and Loki
