S3, EBS, and EFS are all storage services offered by AWS, but they differ in their use cases and characteristics. Here is a brief overview of the differences:
Amazon S3 (Simple Storage Service): S3 is an object-based storage service that is ideal for storing and retrieving large amounts of unstructured data, such as images, videos, and log files. S3 is highly scalable, durable, and cost-effective, and can be accessed from anywhere over the internet.
Amazon EBS (Elastic Block Store): EBS is a block-based storage service that provides persistent block-level storage for EC2 instances. EBS volumes can be used as the boot volume or for storing data and are attached to an EC2 instance via the network. EBS is designed for transactional workloads that require low-latency and high IOPS, such as databases.
Amazon EFS (Elastic File System): EFS is a file-based storage service that provides scalable and highly available NFS-based file storage for EC2 instances. EFS volumes can be mounted to multiple EC2 instances simultaneously, which makes it ideal for shared workloads and data analytics.
In summary, S3 is best for storing and retrieving unstructured data, EBS is ideal for transactional workloads that require low-latency and high IOPS, and EFS is designed for shared workloads and data analytics.
