Lower your AWS costs by optimizing EFS tiering

Leverage EFS Intelligent-Tiering to reduce your AWS spend

— by Beto Juárez III, Solution Architect -

Finding savings: What is EFS tiering?

AWS Elastic File System is a network file system for Linux machines on AWS (EC2 or VMC) that allows you to build a serverless and scalable file system with ease. EFS has two primary storage tiers: Standard and OneZone, each of which has a secondary tier called Infrequent Access (IA).

The main trade-off involved with moving files to this tier is that files in this tier have 10x higher latency, meaning that files in IA should never require quick access by clients or applications.

Realizing savings: How EFS Intelligent-Tiering lowers your costs

EFS comes with “Intelligent Tiering” which allows you to create a lifecycle policy that automatically migrates your less-frequently accessed files to the less-expensive Infrequent Access tier, saving you up to 92% on your EFS bills.

Migrating to IA, however, means that your files will have much lower latency. To ensure that you have the right balance between quick access and cost savings, we created a capacity model that maximizes savings while minimizing any financial or downtime risk. You can read more detailed information here, including instructions on how to implement this same capacity model and lifecycle policies with your own EFS.
