VIP Authentication Hub - EBS( Elastic Block Storage) or EFS( Elastic File Storage) storage for AWS

Products

• VIP Authentication Hub

Issue/Introduction

Please confirm which storage EFS or EBS should be used for product deployment in AWS environment.

Environment

VIP AuthHub 3.1

Resolution

SSP does not require any storage (other than the operational DB). The observability services do (e.g. elastic, Prometheus). Elastic Block Storage(EBS) should be used for better performance.

We researched this and see here: https://www.elastic.co/guide/en/elasticsearch/plugins/7.17/cloud-aws-best-practices.html#_storage

it says:

• EFS-based storage is not recommended or supported as it does not offer satisfactory performance. Historically, shared network filesystems such as EFS have not always offered precisely the behavior that Elasticsearch requires of its filesystem, and this has been known to lead to index corruption. Although EFS offers durability, shared storage, and the ability to grow and shrink filesystems dynamically, you can achieve the same benefits using Elasticsearch directly.
