POSIX Compliance 🖥️: EFS is fully POSIX-compliant, making it ideal for applications requiring shared file systems across multiple EC2 instances, such as web servers and application servers.

Low-Latency Access ⚡: EFS provides lower latency than S3, especially when accessing small files, making it preferable for file-system-like workloads with frequent I/O.

Automatic Scaling 📈: EFS automatically scales as files are added, ensuring no capacity planning worries.

File Locking 🔒: EFS supports file locking natively, making it suitable for applications needing multi-instance access without conflicts (e.g., database files).

⚠️ Note: For archiving or object storage, S3 remains more cost-effective.
