EFS is NAS service that scales across thousands of instances and scales to petabyte scale. … EFS is fully managed — there is no network, hardware or file layer that the end user needs to be responsible for. In order to use the service, AWS offers an EFS mount point.

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.]

What is EFS used for?

Analytics & machine learning. Amazon EFS provides the ease of use, scale, performance, and consistency needed for machine learning and big data analytics workloads. Data scientists can use EFS to create personalized environments, with home directories storing notebook files, training data, and model artifacts.

What is AWS EFS?

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed, elastic NFS file system for use with AWS Cloud services and on-premises resources. Amazon EFS is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily.

What is the difference between NFS and EFS?

NFS is based on a block storage file system that indexes file names. … It is called EFS, and you can mount it via the NFS protocol and get unlimited file storage. Note that it can only be mounted within an AWS VPC, not from your data center via the Internet. But, consider the EFS price as it is more expensive than S3.

Which is faster EBS or EFS?

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.

Is EFS cheaper than EBS?

While EFS does cost more than EBS ($0.30 per GB for EFS vs. $0.10 per GB for EBS), you only pay once per EFS file system. This means that if you attach a dozen instances to it, you will still pay the same amount as if you only had one instance attached to it. With EBS volumes, you pay for each volume.

What is difference between EFS and EBS?

The main differences between EBS and EFS is that EBS is only accessible from a single EC2 instance in your particular AWS region, while EFS allows you to mount the file system across multiple regions and instances. Finally, Amazon S3 is an object store good at storing vast numbers of backups or user files.

What is the difference between BitLocker and EFS?

EFS Encrypts Individual Files

Rather than encrypting your entire drive, you use EFS to encrypt individual files and directories, one by one. Where BitLocker is a “set it and forget it” system, EFS requires you manually select the files you want to encrypt and change this setting.

How does EFS work?

EFS works by encrypting a file with a bulk symmetric key, also known as the File Encryption Key, or FEK. It uses a symmetric encryption algorithm because it takes less time to encrypt and decrypt large amounts of data than if an asymmetric key cipher is used.

What is SMB in AWS?

The AWS Storage Gateway service added the Server Message Block (SMB) protocol to File Gateway, enabling file-based applications developed for Microsoft Windows to easily store and access objects in Amazon Simple Storage Service (S3).

Can I mount EFS on Windows?

You can use an EFS file system as a common data source for workloads and applications running on multiple instances. … 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.

Is EFS free tier?

There is no minimum fee and there are no set-up charges. Amazon EFS offers two storage classes: the Standard storage class, and the Infrequent Access storage class (EFS IA). … To load data into EFS IA, simply enable Lifecycle Management for your file system and reduce your storage costs by up to 92%.
