Amazon Elastic File System Concepts
Internal
Overview
Amazon Elastic File System (EFS) provides a scalable file system for Linux-based workloads for use with AWS cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as files are added and removed. It is designed to provide massively parallel shared access to thousands of Amazon EC2 instances, enabling applications to achieve high levels of aggregate throughput and IOPS with consistent low latencies. Amazon EFS is a fully managed service that requires no changes to existing applications and tools, providing access through a standard file system interface. Amazon EFS is a regional service storing data within and across multiple Availability Zones. The filesystems can be accessed across Availability Zones and regions via AWS Direct Connect or AWS VPN.
Amazon EFS is well suited to support a broad spectrum of use cases from highly parallelized, scale-out workloads that require the highest possible throughput to single-threaded, latency-sensitive workloads. Use cases such as lift-and-shift enterprise applications, big data analytics, web serving and content management, application development and testing, media and entertainment workflows, database backups, and container storage.
