A Stateless Service does not maintain any state internally within the instance across service interactions, i.e. a container does not hold any information from requests in its internal storage (memory or temporary filesystem)
Stateless services are made of identical, replaceable instances that often offload state to external permanent storage systems and use load-balancers for distributing incoming requests
