AWS EFS vs EBS vs S3 (differences & when to use?)

Question

S3 is a storage facility, EBS is a device, EFS is a file system.

Can you please help me in choosing among the three and where

Answer 1

Amazon S3:

• S3 is scalable in nature.
• Amazon S3 is object storage which is suitable for storing user files and backups in massive numbers.
• S3 is the slowest.
• Provides simple object storage, useful for hosting website images and videos, data analytics, and both mobile and web applications.
• S3 service can be accessed from anywhere on the internet.
• It is great for short term archiving and for the long term the Glacier becomes costly. Glacier is a storage system which is used for backup and archiving data.
• S3 is a web system interface.

Amazon EBS:

• EBS is hardly scalable and provides block storage
• Amazon EBS can also enhance the functionality of Amazon EC2 - it is similar to your computer's drive but in a virtualized environment
• EBS is the fastest amongst the three and relatively cheap
• Provides persistent block-level data storage. It blocks storage stores files in multiple volumes called blocks, which act as separate hard drives; block storage devices are more flexible and offer higher performance than regular file storage.
• It only exists in a particular region.
• EBS is a file system interface.

Amazon EFS:

• Amazon EFS was designed to provide scalable object storage for the users of Amazon EC2 cloud computing service.
• EFS is slower than EBS and faster than S3
• Is a shared, elastic file storage system that can grow and shrinks as you add or remove files. It provides a traditional file storage paradigm, with data organized into directories and subdirectories.
• It is useful for SaaS applications and content management systems
• It has more features but it is more costly
• EFS is both web and file system interface.
