Amazon EFS एक अमेज़न वेब सर्विस है इस पोस्ट में हम इसके बारे में अच्छे से जानेंगे What is Amazon EFS in Hindi की Amazon EFS किसे कहते है।
What is Amazon EFS in Hindi?
EFS(Elastic file system) is a file-level storage service that basically provides a shared elastic file system with virtually unlimited scalability support. EFS is highly available storage that can be utilized by many servers at the same time. AWS EFS is a fully managed service by amazon and it offers scalability on the fly. This means that the user need not worry about their increasing or decreasing workload. If the workload suddenly becomes higher then the storage will automatically scale itself and if the workload decreases then the storage will itself scale down. This scalability feature of EFS also provides cost benefits as you need not pay anything for the part of storage that you don’t use, you only pay for what you use(Utility-based computing).
One most important feature of EFS that makes it different from all other storage is that the IOPS rate in EFS is inversely proportional to the size of data. For example, if the size of data is less, then the performance and IOPS rate might be not much significant but when used more heavily, EFS can offer as much as 10 GB/sec along with 500,000 IOPS.
Comparison based on Characteristics:
EBS(elastic block storage) & EFS(elastic file system), as the name suggests EBS is block-level storage and EFS is file-level storage.
As we know that EBS is directly attached to the instance so there is no sign of the term availability in it whereas Amazon EFS is highly durable and highly available storage.
EBS is similar to hard disks but the only difference is that EBS is connected to virtual EC2 instances and it offers 20 times more reliability than normal hard disks.
EFS is highly durable storage.
EBS offers a Baseline performance of 3 IOPS per GB for General Purpose volume and also we can use Provisioned IOPS for increased performance whereas EFS supports up to 7000 file system operations per second.
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.
Comprehensive managed service
EFS is a completely managed service, which means that your firm will never have to patch, deploy, or maintain your file system, but the same is not the case with EBS.
One most important disadvantage of EBS is that it cannot be accessed directly via the internet, it can only be accessed by a single EC2 instance with whom it is connected, whereas EFS storage allows access of 1 to 1000s of EC2 instances concurrently via the internet but these instances must be present in the same region only.
Both EBS and EFS supports encryption and uses an AWS KMS–Managed Customer Master Key (CMK) and AES 256-bit Encryption standards for encryption.
File Size Limitation
As EBS is directly connected to the EC2 instance so we have don’t have any limitation on file size whereas in EFS the maximum size of a single file can be up to 47.9TiB.
EFS is the only storage in which you’ll pay for is exactly what you use, as there’s no advance provisioning, up-front fees, or commitments whereas in EBS you need to attach a fixed amount of volume, and you are charged for the same.
Amazon EFS use cases:
- Lift-and-shift application support: EFS is elastic, highly available, and highly scalable storage, and these all features and enables users to move enterprise applications easily and quickly.
- Analytics for big data: EFS has got the ability to run big data applications.
- Web server support: EFS is a highly robust throughput file system and is capable of enabling web serving applications, such as websites, or blogs.
- Application development and testing: Among different storages provided by Amazon EFS is the only one that provides a shared file system needed to share code and files.
Let us see the differences in a tabular form -:
|Amazon EBS||Amazon EFS|
|1.||The full form of Amazon EBS is Amazon Elastic Block Store||The full form of Amazon EFS is Amazon Elastic File System|
|2.||It is used to provide the block-level storage volumes for the use of EC2 instances.||It is simple to use.|
|3.||It is mainly used for data that should be quickly accessible and requires long term durability.||It is used in modernize application development|
|4.||It is suitable for both types of database-style applications -:
1. Those rely on random reads
2. Those rely on random writes.
|Industries use this for enhancing content management systems|
