Policy: AWS > Well-Architected Tool > AWS Well-Architected Framework > Reliability > REL 05. How do you design interactions in a distributed system to mitigate or withstand failures? > Make services stateless where possible

Services should either not require state, or should offload state such that between different client requests, there is no dependence on locally stored data on disk or in memory. This enables servers to be replaced at will without causing an availability impact. Amazon ElastiCache or Amazon DynamoDB are good destinations for offloaded state.

See Make services stateless where possible for more information.
