Efs storage class

What type of storage is EFS?

EFS is a file storage service for use with Amazon compute (EC2, containers, serverless) and on-premises servers. EFS provides a file system interface, file system access semantics (such as strong consistency and file locking), and concurrently accessible storage for up to thousands of EC2 instances.

What is EFS storage in AWS?

Amazon Elastic File System (Amazon EFS) is a simple, serverless, set-and-forget, elastic file system. There is no minimum fee or setup charge. You pay only for the storage you use, for read and write access to data stored in Infrequent Access storage classes, and for any provisioned throughput.

Is EFS a SSD?

EFS is based on SSD volumes that are replicated across multiple AZs in an AWS region. As a type of NAS, multiple EC2 machines can access an EFS from different zones within the same region or even from different regions.

Is EFS object based storage?

Amazon EFS is easy to use offering a simple interface that allows you to create and configure file systems quickly and easily. While Amazon EFS supports file storage, Amazon Web Services also provides support object storage with Amazon S3 and block storage with Amazon EBS.

Is EFS a SAN or NAS?

[EFS is a NAS, but again under the hood on an Storage Array , managed with sync, replication, scalability etc.]

How does EFS store the files?

Amazon EFS file systems using Standard storage classes store data and metadata across multiple Availability Zones in an AWS Region. EFS file systems can grow to petabyte scale, drive high levels of throughput, and allow massively parallel access from compute instances to your data.

How is EFS different from S3?

Amazon S3 (Amazon Simple Storage Service) is an object storage designed for storing large numbers of user files and backups. Amazon EFS (Amazon Elastic File System) provides scalable network file storage for Amazon EC2 cloud computing service users.

What are the different types of EFS?

Amazon EFS offers a range of storage classes that are designed for different use cases. These include EFS Standard, EFS Standard–Infrequent Access (Standard-IA), EFS One Zone, and EFS One Zone–Infrequent Access (EFS One Zone-IA).

Why is EFS faster than S3?

EFS has the simplest cost structure. Amazon S3 can be accessed from anywhere. AWS EBS is only available in a particular region, while you can share files between regions on multiple EFS instances. EBS and EFS are both faster than Amazon S3, with high IOPS and lower latency.

Why is EFS used?

EFS is a user-based encryption control technique that enables users to control who can read the files on their system. The typical method of using EFS is to perform encryption at the folder level. This ensures that all files added to the encrypted folder are automatically encrypted.

What is EFS good for?

Amazon EFS provides a comprehensive encryption solution to help you secure both your stored data and data in flight. Data at rest is transparently encrypted using encryption keys managed by the AWS Key Management Service (KMS), eliminating the need to build and maintain a key management infrastructure.

Is EFS for cold storage?

Amazon EFS supports transitioning backups from warm to cold storage using lifecycle rules, so we also discuss optimizing the cost of EFS file system backups using lifecycle rules.

Is EFS a database?

Amazon EFS is an effective solution for backing up database workflows. It offers fully managed POSIX-compliant file storage that scales to petabytes on demand for changing backup sizes. It also sets the bar with the availability and durability needed for restores at an effective price of just $0.08/GB-month*.

Is EFS encrypted at rest?

Amazon EFS uses industry-standard AES-256 encryption algorithm to encrypt EFS data and metadata at rest.

Can we install OS in EFS?

What you can't do is boot an EC2 instance from EFS, so installing the OS on an EFS filesystem would not work.

Is EFS for cold storage?

Amazon EFS supports transitioning backups from warm to cold storage using lifecycle rules, so we also discuss optimizing the cost of EFS file system backups using lifecycle rules.

Is EFS a database?

Is EFS a Network File System?

You have created your first network file system in the cloud. Amazon EFS is a simple, scalable shared file system that grows and shrinks automatically as you add and remove files, and you only pay for the amount of storage you are using.

Is EFS faster than S3?

EBS and EFS are both faster than Amazon S3, with high IOPS and lower latency.

What is EFS good for?

Is EFS encrypted at rest?

Amazon EFS uses industry-standard AES-256 encryption algorithm to encrypt EFS data and metadata at rest.

What is difference between S3 and EFS?

Where does EFS store data?

The EFS One Zone storage classes are lower cost, single Availability Zone storage classes. They store file system data and metadata redundantly in a single Availability Zone within an AWS Region.

Is EFS just NFS?

Amazon EFS is an NFS file system service offered by AWS. An Amazon EFS file system is excellent as a managed network file system that can be shared across different Amazon EC2 instances and works like NAS devices. Amazon EBS is the block storage offered on AWS.

What files are EFS encrypted?

The Encrypted File System, or EFS, provides an additional level of security for files and directories. It provides cryptographic protection of individual files on NTFS file system volumes using a public-key system.
