Upload and Delete files with Amazon S3 and Spring Boot

Introduction

As a developer, i am pretty sure that you may have come across with scenarios where you need to store images (either user uploaded or application itself) of your application.  There are several possibilities to store file(s) as follows.

• Store the file(s) somewhere in the hosting server where the application is deployed (if it is a web application).
• Store the file(s) in the database as binary files.
• Store the file using cloud storage services.

Here we are going to evaluate the third option (given above) which is “Store the file using cloud storage services“.

Amazon Simple Storage Service (S3) is an AWS object storage platform which helps you to store the files in form of objects, and, store and retrieve any amount of data from anywhere.  Each file stored in Amazon S3 (as an object) is represented using a key.
