There are Helm charts available for all Grafana products so if you already run a Kubernetes cluster and have spare capacity you can just throw it up there. Loki supports shipping logs to GCS/S3 natively and Prometheus can use Cortex (also available as a Helm chart) to do the same. Once you throw Grafana behind SSO and implement a backup cronjob you're done until you reach scale and have to start deploying/scaling individual components separately. I implemented most of the above using Terraform on a managed DigitalOcean cluster on a Saturday a few months back; it wasn't super-hard. Alternatively you could rent a few VPSes someplace and use k3s or similar to get an unmanaged cluster.
