We chose to use Amazon S3 to store the build of our React website as uploading the build that npm generates of our React website to an Amazon S3 website is seamless using the AWS CLI. Amazon S3 also provides primitive website hosting features for fast viewing of a developer version of our website, which contributed to our reasoning to use S3 to store the build of our React site as it will enable us to store the website build while also providing a dev website that won't be visible to customers immediately.
