+# Profile
+
+VAuthenticator can be configured to be strongly AWS integrated using DynamoDB for the persistence layer and KMS for Key management. 
+
+If your organization or for you run VAuthenticator so tiny integrated with AWS does not is suitable you can decide to switch postgresql instead dynamodb for the persistence
+and plain java security key management instead of KMS
+
+All what you need is enable the relative spring profile as below:
+
+use ```spring.profiles.active``` with 
+
+- ```database```: to use PostgresSQL 
+- ```dynamo```: to use DyanamoDB
+- ```kms``` to use KMS
+- omitting ```kms``` to use plain java security api
+
+in case of plain java security implementation the follow configuration is required:
+
+
+```yaml
+key:
+  master-key:
+    storage:
+      content:
+        key : value
+        key2 : value2
+```
