Amazon Web Services introduced a fully managed service to simplify the process of setting up and scaling file storage in the AWS Cloud.
Amazon Elastic File System (Amazon EFS) can be used to create file systems that are accessible to multiple Amazon Elastic Compute Cloud (Amazon EC2) instances via the Network File System (NFS) protocol. Amazon EFS can automatically scale without needing to provision storage or throughput, enabling file systems to grow seamlessly to petabyte scale, while supporting thousands of concurrent client connections with consistent performance. Amazon EFS is designed to support a broad range of file workloads – from big data analytics, media processing, and genomics analysis that are massively parallelized and require high levels of throughput, to latency-sensitive use cases such as content management, home directory storage, and web serving.
