Accessing data from AWS using S3

AWS is one of the most popular cloud providers, mixing different service architectures and allowing easy and fast implementations.

While it has various solutions for relational and non-relational databases, in this recipe, we will cover how to manage data access from S3 buckets, which is an object storage service allowing not only text files to be uploaded, but also media and several other types of files used in the IoT and big data fields.

There are two commonly used types of data access management for S3 buckets, both used on ingest pipelines – user control and bucket policies. In this recipe, we will learn how to manage access by user control, given that it is the most used method among data ingestion pipelines.

Getting ready

To do this recipe, having or creating an AWS account is not mandatory. The objective is to build a step-by-step Identity Access Management (IAM) policy to retrieve data from an S3 bucket using good data access...
