5 documented AWS EFS cost inefficiencies, each with how to detect it and how to fix it.

## 5 inefficiencies

[All services](https://www.pointfive.co/efficiency-hub#browse-by-service)

- AWS EFS  CER-0198

### [Suboptimal Use of EFS Storage Classes](https://www.pointfive.co/efficiency-hub/inefficiencies/suboptimal-use-of-efs-storage-classes)

Many organizations default to storing all EFS data in the Standard class, regardless of how frequently data is accessed. This results in inefficient spend for workloads with significant portions of data that are rarely read. EFS IA and...

- AWS EFS  CER-0123

### [Overprovisioned Throughput in EFS](https://www.pointfive.co/efficiency-hub/inefficiencies/overprovisioned-throughput-in-efs)

When file systems are launched with Provisioned Throughput, teams often overestimate future demand - especially in environments cloned from production or sized "just to be safe." Over time, many workloads consume far less throughput than...

- AWS EFS  CER-0143

### [Missing Lifecycle Policy on Replicated EFS File System](https://www.pointfive.co/efficiency-hub/inefficiencies/missing-lifecycle-policy-on-replicated-efs-file-system)

When replicating an EFS file system across AWS regions (e.g., for disaster recovery), the destination file system does not automatically inherit the source's lifecycle policy. As a result, files replicated to the destination will remain in...

- AWS EFS  CER-0190

### [Missing Intelligent-Tiering on EFS Lifecycle Policy](https://www.pointfive.co/efficiency-hub/inefficiencies/missing-intelligent-tiering-on-efs-lifecycle-policy)

EFS offers lifecycle policies that transition files from the Standard tier to Infrequent Access (IA) based on inactivity, significantly reducing storage costs for cold data. When this feature is not enabled, infrequently accessed files...

- AWS EFS  CER-0018

### [Inactive and Unmounted EFS File System](https://www.pointfive.co/efficiency-hub/inefficiencies/inactive-and-unmounted-efs-file-system)

EFS file systems that are no longer attached to any running services - such as EC2 instances or Lambda functions - continue to incur storage charges. This often occurs after workloads are decommissioned but the file system is left behind....
