Amazon Elastic File System (Amazon EFS), is well-known for its serverless, set-and-forget elastic file system. This allows you to share file data with no storage provisioning or management. This may also use AWS Cloud services and other on-premises resources to scale up to petabytes per hour without affecting applications.
Amazon EFS also supports a wide variety of use cases, including personal directories and operation applications. You can store for some use cases.
First, containerized and serverless apps
Secondly, big data analytics
Web serving and content management are the third.
Next comes application development and testing
Media and entertainment workflows are then created.
Database backups are also important.
Amazon EFS:
First, you can share code and other files in an organized, safe way with Elastic File System. This will allow DevOps to respond quickly to customer feedback and increase agility.
This allows you to share and persist data from your AWS containers or serverless applications without the need for management.
Third, Amazon EFS allows you to clarify persistent storage for modern content management systems (CMS) workloads. You can also get products and services at a lower price that offer greater reliability and security.
It also provides the consistency and performance required for machine learning (ML), and big data analytics workloads.
Amazon EFS (Elastic File System).
Amazon Elastic Files System (Amazon EFS), allows you to automatically grow and shrink. You can also add and delete files automatically without the need for management or provisioning.

The most important features of Amazon EFS (Elastic File System), are:
1. Fully managed
Amazon EFS is a fully managed service that provides Linux workloads with NFS shared storage.
It also helps you create and configure file systems.
Update hardware
Configuring software
Backups are essential.

2. Highly available and durable
Amazon EFS offers high availability and durability. Amazon EFS files are stored in multiple Availability Zones (AZs), which are used for file systems that use Standard storage classes. If you choose Amazon EFS One Zone storage class, your data will be stored in a single AZ.
3. Storage classes & lifecycle management
Amazon EFS offers Standard and One Zone storage classes to store frequently accessed and rarely accessed files. The performance-optimized Standard and One Zone storage classes are designed to give continuous low latencies. The Amazon EFS Standard Infrequent Access (EFS Standard IA) and Amazon EFS One Zone Infrequent Access (EFS One Zone IA) storage classes are cost-optimized to store files that are less frequently accessed. It also enables EFS Lifecycle Management of your file system and selects an appropriate age-off policy to start saving money on storage (7-14, 30, 60, and 90 days).
4. Security & compliance
You will have complete network access control using Amazon Virtual Private Cloud (Amazon VPC security group rules in EFS). AWS Identity and Access Management rules and EFS Access Points can also be used to control application access to your file system.
5. Scalable performance
Amazon EFS provides the performance, IOPS and low latency required by a wide range workloads. As file system Throughput and IOPS grow, Amazon EFS can support the unpredictable performance requirements of file workloads by delivering higher throughput levels at shorter intervals.
6. Performance modes
Amazon EFS is designed for high throughput, IOPS and low latency to support a variety of workloads. It also comes with two performance modes.
General Purpose
This option provides the shortest latency per operation on a file system and can be used for both sequential and random IO patterns.
Max I/O
Max I/O is suited to highly parallelized applications that can scale upto thousands of Amazon EC2 instances. It can scale to higher aggregate throughputs per second.
7. Modes for throughput
The throughput mode is used to determine the file system’s overall throughput. Amazon EFS offers two throughput modes.
Bursting
Throughput scales with file size, dynamically bursting when necessary to meet the spiky nature of many file-based workloads.
Provisioned.
This mode is intended to support applications that require higher dedicated throughput than the default bursting mode. It can be configured independently from the data stored on the filesystem.
8. Elastic and scalable
Amazon EFS offers elastic storage capacity. It is elastic with Amazon EFS. This means that it changes as you add or remove files. This dynamically provides the storage capacity to applications when they need it. Amazon EFS is highly scalable in terms of storage capacity and throughput performance. It can scale up to petabytes, and allows massively parallel access from Amazon EC2 instances to your data.
9. Encryption
Amazon EFS provides encryption for data at rest and transit. It offers a comprehensive encryption solution that protects both stored data and flight data. Data at rest is encrypted transparently using encryption keys managed through the AWS Key Management Service. This eliminates the need to create and maintain a key management infrastructure. Data in transit encryption uses industry-standard Transport Layer Security, (TLS), to protect network traffic without any modifications to your apps.
10. Backup & data transfer
AWS DataSync
AWS DataSync is a managed data transfer service that can be used to transfer data between different locations.
