Which feature of AWS allows secure access management for cloud resources?

Identity and Access Management (IAM) is the feature of AWS that allows for secure access management to cloud resources. IAM enables users to manage access to AWS services and resources securely. It provides fine-grained control over user permissions, allowing administrators to define who can access specific resources and what actions they can perform.

Through IAM, users can create and manage AWS users and groups and use permissions to allow or deny access to AWS resources. This level of control is crucial for maintaining the security and integrity of cloud environments, ensuring that only authorized users have access to sensitive data and critical resources. Additionally, IAM supports multi-factor authentication (MFA), which enhances security by requiring users to provide multiple forms of verification before granting access.

The other features listed do not directly relate to access management. Elastic Load Balancing is focused on distributing incoming application traffic across multiple targets to ensure high availability and reliability. Amazon VPC (Virtual Private Cloud) enables users to create isolated virtual networks within the AWS cloud but does not manage user access. AWS CloudFormation helps automate resource provisioning through templates but does not address access management. Therefore, IAM stands out as the primary feature for secure access management in AWS.
