This guide will explain about ephemeral storage in AWS Lambda.
What is Ephemeral Storage in AWS Lambda?
Ephemeral storage is used to store data temporarily and it gets removed as soon as the service is terminated. Amazon Lambda service supports ephemeral storage of up to 10,240 MBs which is a huge increase as the previous size was 512 MBs. Lambda uses different storage services like S3, temporary storage with “/tmp”, etc for its functions.
