+
+## Context and Problem Statement
+
+We need a place to host and run the MCFD Mobility middleware API.
+
+## Considered Options
+
+* OpenShift
+* No other options were considered
+
+## Decision Outcome
+
+Chosen option: "OpenShift", because no other options were considered.
+
+### Consequences
+
+* Good, because OpenShift is provided as a free private cloud service to BC Gov at large
+* Good, because there is a growing internal community to draw support from
+* Good, because of Kubernetes' reliability
+* Good, because we can use Helm for Infrastructure as Code
+* Good, because we can set up CI/CD for rapid development and easier deployments
+* Bad, because OpenShift can be difficult to learn, making developer onboarding require more effort
+
+### Confirmation
+
+Work with members of ARB to review Helm charts and confirm the architecture is set up correctly.
