 Once the secrets/access tokens are retrieved, they are then stored in a shared [Amazon Elastic File System](https://aws.amazon.com/efs/) (EFS) volume. This volume is then made accessible to your application and all of its replicas.
 
 This guide primarily focuses on integrating Infisical Cloud with Amazon ECS on AWS Fargate and Amazon EFS.
