AWS (Amazon Web Services) offers a cloud computing platform that provides a wide range of services for building and managing various types of applications and infrastructure. AWS accounts are the fundamental entities used to access and utilize AWS services. Here’s some information about AWS accounts:
- AWS Account: An AWS account is the primary entity used to access and use AWS services. It serves as a container for resources and billing information. When you create an AWS account, you obtain a unique AWS account ID and gain access to the AWS Management Console, where you can manage your account and services.
- Root Account: The root account is the initial AWS account created when you sign up for AWS. It has full administrative privileges, allowing you to manage all aspects of your AWS resources and services. It’s crucial to secure the root account using strong credentials and enable multi-factor authentication (MFA) for enhanced security.
- IAM (Identity and Access Management) Users: IAM allows you to create multiple users within your AWS account, each with unique credentials and access permissions. IAM users enable you to grant fine-grained permissions to individuals or applications, helping you adhere to the principle of least privilege and enhance security. IAM users can be assigned to groups, and policies can be applied to grant or restrict access to AWS resources.
- IAM Roles: IAM roles are similar to IAM users but are designed for specific use cases, such as granting temporary permissions to an AWS service or allowing cross-account access. IAM roles are assumed by trusted entities, like IAM users or AWS services, through a process called role assumption.
- AWS Organizations: AWS Organizations is a service that enables you to manage multiple AWS accounts centrally. It helps you consolidate billing, establish policies across accounts, and simplify resource management. With AWS Organizations, you can create member accounts, define organizational units (OUs) to group accounts, and apply policies at different levels.
- AWS Consolidated Billing: Consolidated billing is a feature of AWS Organizations that allows you to consolidate the payment for multiple AWS accounts under a single paying account. It simplifies billing by providing a comprehensive view of costs across accounts, making it easier to allocate expenses and manage budgets.
- Cross-Account Access: AWS allows you to grant permissions for resources in one AWS account to users or services from another account. This is useful for scenarios where you want to share resources securely between accounts or allow third-party applications access to your resources.
Remember, AWS accounts serve as a logical and administrative boundary for managing resources and access control. It’s essential to follow AWS security best practices and configure appropriate permissions to ensure the confidentiality, integrity, and availability of your AWS resources.
