What is Boto 3 primarily used for?

Boto 3 is primarily used as a Software Development Kit (SDK) for Python, which facilitates interaction with various AWS services. By providing a Pythonic interface to the AWS APIs, Boto 3 simplifies the process of building applications that utilize AWS resources, such as S3 for storage, EC2 for computing, and DynamoDB for databases. Developers can easily create, manage, and manipulate AWS services programmatically using Python, leveraging the capabilities of the AWS cloud infrastructure.

The other options, although related to AWS, focus on specific functionalities that Boto 3 does not primarily address. Managing user accounts in AWS is typically handled through AWS IAM (Identity and Access Management), while cost analysis generally falls under the purview of AWS Cost Explorer or AWS Budgets. Monitoring network performance in AWS would involve using services like Amazon CloudWatch or AWS X-Ray. Hence, these options do not capture the main purpose of Boto 3, which is to serve as an SDK for Python for interacting with AWS services.
