Amazon Simple Storage Service, or simply Amazon S3, is a secured and highly scalable data storage service offered as part of Amazon Web Services. With its simple and intuitive interface, S3 makes the task of storing and retrieving data from anywhere on the web relatively easy. The best part of S3 is its remarkable ability to create replicas of your data automatically. So you don't have to worry about losing any important information.

Amazon S3 Integration Overview

Contentstack's Experience Extensions offer a variety of ways to integrate third-party applications, such as Amazon S3, directly into your headless CMS. You can set up the extension to fetch content (images, files, and so on) from your Amazon S3 account and insert it in entries of a content type.

Using a Contentstack Custom Field, you can embed and display information of your S3 bucket items from your Amazon S3 account directly in the CMS environment. You just need to add the extension in your entry and access your S3 files and documents, all without leaving your CMS.
