 This process ensures a seamless update experience, minimizing user disruption during deployments. If needed, you can also manage traffic splitting between versions during the update process, allowing you to test new versions with a subset of traffic before fully migrating to it
 
-## Stateless application
+## Stateless
 
-A stateless application is a computer program that does not save client data between sessions. Data generated in one session is not saved for use in the next session with that client.
+Refers to a system or application that does not maintain any persistent state between executions. In a stateless environment, each request or operation is independent, and no information is retained from previous interactions.
 
-To store data persistently, use products like [Managed Databases]/managed-databases/) or [Object Storage](/storage/object/).
+This means that each request is treated as a new and isolated event, and there is no need for the system to remember previous states or data once a task is completed. Statelessness is commonly used in serverless architectures where each function execution is independent of others.
+
+To store data you can use [Scaleway Object Storage](/storage/object/), [Scaleway Managed Databases](/managed-databases/postgresql-and-mysql/), and [Scaleway Serverless Databases](/serverless/sql-databases/).
