EFS: A Shared File System for Your Lambda Functions

Amazon EFS provides a persistent file system for Lambda, allowing multiple functions to read and write to the same data simultaneously. This is ideal for sharing large files like ML models, processing common datasets, or maintaining state across invocations. By mounting EFS to your Lambdas in a VPC, they gain access to a shared and scalable file system!
