+# 5. Use Cloud Run and Containers for compute
+
+Date: 2024-09-30
+
+## Status
+
+Accepted
+
+## Context
+
+It is probable that the service will need to change cloud provider at some point in its live, possibly relatively soon. The service will also experience large fluctuations in load. 
+
+## Decision
+
+Build the service in containers, using Docker. This will allow us to move the service more easily to a different cloud provider when required and minimise the complexity of the service. 
+
+Use Cloud Run to run the containers. This will allow us to build a service that scales with demand and is a simpler service to manage than Google Kubernetes Engine.

+## Consequences
