Architecture & Usage Recommendations
- Place compute instances (EC2, ECS, EKS) in the same Availability Zone as the file system to avoid cross-AZ data transfer fees.
- Enable AWS Backup automatic policies for file systems containing important single-AZ data.
- One Zone file systems can also leverage One Zone-IA lifecycle policies for additional savings.
