Cloud storage is an essential component of cloud computing,

AWS offers a full range of storage services but this can cause a bit of confusion for users when choosing the right service that fits their specific needs.


For this reason, in this post we are going to analyze the 3 main AWS Storage services that are Amazon Elastic Block Store (Amazon EBS), Amazon Simple Storage Service (Amazon S3) and Amazon Elastic File System (Amazon EFS).


Through this comparison, what we want is to give you the necessary tools to identify the best option that suits your needs.

But before moving on to the comparison, we first start by defining each of these services.


What is Amazon S3?


It is an object storage service designed to back up and archive data and applications online on Amazon web services.

Each object is stored as a file with its metadata included and is assigned an identification number.

What is Amazon EBS?


It is a service that provides persistent (long-term) block storage with the AWS EC2 instance. The volumes stored in EBS are automatically replicated within an Availability Zone to be protected against errors and disasters that can occur, offering high availability and durability.

EBS is typically used to provide backup and disaster recovery or more traditional storage for cloud workloads, which may be the case for relational databases and other Business Applications.

What Is Amazon EFS?

This service offers scalable and elastic simple storage based on Solid State Disks (SSD) on demand for EC2 instances and scales based on storage needs, offers a simple interface that allows you to create and configure file systems quickly and easily.

EFS is highly recommended for short-term tasks that can be performance-sensitive, such as development environments. This service can also be used in long-term tasks such as data repository for media servers for example.


Since we have the three services defined, we proceed to make a comparison based on costs, size, performance, and other characteristics that will allow you to choose the correct and appropriate option for your needs.
