The AWS Simple Storage Service (S3) from Amazon Web Services (AWS) is a widely used cloud storage option for securely overseeing and storing your data. The AWS Command Line Interface (CLI) offers a robust and effective means of engaging with various AWS services, including S3. Within this article, we will provide you with step-by-step instructions on how to utilize the AWS CLI to upload files to AWS S3.
What is AWS?
Amazon provides Amazon Web Services (AWS), a highly utilized and all-encompassing platform and infrastructure for cloud computing.
