+Deployment / Infrastructure
+----------------------------
+
+Stingray is deployed as containers running on the station.
+For each statistic type (XST, SST, BST) and each antenna field, one container instance is running.
+
+Each container is receiving the statistics packets for a specific type and antenna field via TCP,
+recording them in chunks of up to 5 minutes and writing the result JSON encoded to a S3 bucket.
+
+The bucket is located on the stations MinIO instance and configured to replicate the individual objects
+to the central MinIO instance. To reduce the risk of data loss the objects are stored on the station for 24 hours.
