S3 Bucket

S3 is an AWS (Amazon web service) product that offers data storage, scalability, and security. With S3, you can store data of various sizes and kinds such as text, file, object, videos, backup and more.

Additionally, with S3 you can store an unlimited amount of data and retrieve the data easily.

In this article, we will discuss the basic of s3 and how to store and retrieve data well as security options and storage class.

“S3” is a short term for Simple Storage Service

How AWS S3 works

S3 operates an object storage system, instead of your normal file storage system, which means that its architecture exists across flat address space and each data is referenced by a unique url or assigned to a url.

Furthermore, S3 stores data based on region to improve accessibility, versionizing, durability and security and it stores duplicates of your data so it’s safe to say you can’t lose your data in S3 either to corruption or degradation of data.

To store data in S3, you first need to create or use an existing bucket.

Bucket: Buckets are containers used to store data or directories to aid with categorisation or data management.

Storage classes:

Amazon S3 Standard: This is the default storage and suitable for frequent data access

S3 Standard Infrequent Access: This is mainly used to store data that aren’t often used but still need to access that data easily and quickly.

S3 One Zone: This is similar to the standard infrequent access class but has low latency and mostly used for backup copy storage

S3 Intelligent Tiering: This class offers data accessibility via changing access patterns(frequency and infrequent access).
