What is EFS in AWS?

What is EFS 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.

What is the difference between AWS EBS and EFS?

The data stored in EBS remains in the same availability zone and multiple replicas are created within the same availability zone whereas in EFS the data stored remains in the same region and multiple replicas are created within the same region.

What is EFS used for?

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.

Is EFS faster than S3?

EBS and EFS are both faster than Amazon S3, with high IOPS and lower latency. EBS is scalable up or down with a single API call. Since EBS is cheaper than EFS, you can use it for database backups and other low-latency interactive applications that require consistent, predictable performance.

What is difference between S3 and EFS?

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.

Is EFS a NAS?

EFS is NAS service that scales across thousands of instances and scales to petabyte scale. This scaling is helped by the fact that the storage capacity management is handled automatically by the platform itself.

Is EFS a SAN or NAS?

EFS provides shared access to fully managed file systems across-the-board. Connecting to EFS is similar to connecting to your network drive since it supports NFS protocols, which are standard for network attached storage (NAS) devices. As a result, you can connect to it through your network interface.

Is EFS a block storage?

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. Amazon Elastic Block Store (EBS) is a block-level storage service for use with EC2.

What kind of storage is EFS?

AWS Elastic File System (EFS) is one of three main storage services offered by Amazon. It is a scalable, cloud-based file system for Linux-based applications and workloads that can be used in combination with AWS cloud services and on-premise resources.

Is EFS in a VPC?

You can mount an Amazon EFS file system in your virtual private cloud (VPC), through the Network File System versions 4.0 and 4.1 (NFSv4) protocol.

Does EFS require EC2?

An EFS is created within an AWS Virtual Private Cloud (AWS VPC) and must be attached to EC2 instances within the same VPC.

Can EFS be used for database?

Storage Interface Many customers use Amazon EFS for database backups, because most backup software has standard support to write backups to files. This means you can simply mount your EFS file system to your database and backup to a path on EFS.

What is the maximum size of EFS?

Maximum size of a single file: 52,673,613,135,872 bytes (47.9 TiB). Maximum directory depth: 1,000 levels deep. Any one particular file can have up to 512 locks across all instances connected and users accessing the file. Amazon EFS file system policies have a 20,000 character limit.

Can I mount EFS on Windows?

Amazon EFS is not supported on Windows instances. To use Amazon EFS with a Linux instance, see Amazon Elastic File System (Amazon EFS) in the Amazon EC2 User Guide for Linux Instances.

Why is EFS slow?

As applications use more throughput, burst credits are used. Applications that use too much I/O are penalized, and EFS throttles performance, one of the potential causes for slow EFS performance.

What is AWS EBS vs S3?

Both S3 and EBS gives the availability of 99.99%, but the only difference that occurs is that S3 is accessed via the internet using API’s and EBS is accessed by the single instance attached to EBS.

Why EBS is used in AWS?

Amazon Elastic Block Store (Amazon EBS) provides block level storage volumes for use with EC2 instances. EBS volumes behave like raw, unformatted block devices. You can mount these volumes as devices on your instances.

What is Elastic Beanstalk vs EC2?

EC2 is Amazon’s service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances. Elastic Beanstalk is one layer of abstraction away from the EC2 layer.
