Amazon RDS provides a managed database service that supports MariaDB with minimal operational overhead. It handles routine database tasks such as backups, patching, and scaling, reducing the burden on users. Amazon Neptune and DynamoDB are not compatible with MariaDB, and Amazon S3 is not a relational database service.

Understanding IAM Roles: IAM (Identity and Access Management) roles in AWS are designed to delegate access permissions without sharing long-term security credentials. This means applications and services can use temporary security credentials, which enhances security.

Why IAM Roles are Best Practice:

Least Privilege Principle: By using IAM roles, you can ensure that applications only have the minimum permissions they need to function, reducing the risk of unauthorized access.

Temporary Credentials: Roles provide temporary security credentials, which reduce the risk if they are compromised compared to long-term access keys.

Automated Rotation: Temporary credentials automatically expire and are rotated, which means you don’t have to manage the rotation manually.

How to Implement IAM Roles:

Create an IAM Role: In the AWS Management Console, navigate to IAM, and create a new role. Choose the type of trusted entity (e.g., EC2, Lambda).

Attach Policies: Attach the necessary policies to the role that define the permissions for accessing the S3 bucket.

Assign Role to Service: Attach the IAM role to your EC2 instances, Lambda functions, or other AWS services that need to access the S3 bucket.

Use AWS SDKs: When accessing S3 from your application, use the AWS SDKs to automatically assume the IAM role and obtain temporary credentials.

These are two of the seven capabilities that are in the platform perspective of the AWS Cloud Adoption Framework (AWS CAF). The platform perspective helps you build an enterprise-grade, scalable, hybrid cloud platform, modernize existing workloads, and implement new cloud-native solutions1. The other five capabilities are:

Platform architecture – Establish and maintain guidelines, principles, patterns, and guardrails for your cloud environment.

Platform engineering – Build a compliant multi-account cloud environment with enhanced security features, and packaged, reusable cloud products.

Platform operations – Manage and optimize your cloud environment with automation, monitoring, and incident response.

Application development – Develop and deploy cloud-native applications using modern architectures and best practices.

Application migration – Migrate your existing applications to the cloud using proven methodologies and tools.

Performance and capacity management, infrastructure protection, and change and release management are not capabilities of the platform perspective. They are part of the operations perspective, which helps you achieve operational excellence in the cloud2. The operations perspective comprises six capabilities:

Performance and capacity management – Monitor and optimize the performance and capacity of your cloud workloads.

Infrastructure protection – Protect your cloud infrastructure from unauthorized access, malicious attacks, and data breaches.

Change and release management – Manage changes and releases to your cloud workloads using automation and governance.

Configuration management – Manage the configuration of your cloud resources and applications using automation and version control.

Incident management – Respond to incidents affecting your cloud workloads using best practices and tools.

Service continuity management – Ensure the availability and resilience of your cloud workloads using backup, recovery, and disaster recovery strategies.

AWS VPN and AWS Direct Connect are two services that enable customers to connect their on-premises data center network to the AWS Cloud. AWS VPN establishes a secure and encrypted connection over the public internet, while AWS Direct Connect establishes a dedicated and private connection through a partner network.

IAM Users and Billing Permissions:

IAM users with appropriate permissions can access and view the AWS Billing console.

The root user is required only for certain account-level tasks, such as changing support plans or closing accounts.

Why Other Options Are Incorrect:

A. Change to a different AWS Support plan: Requires root user credentials.

B. Close an AWS account: Requires root user credentials.

D. Activate access to the AWS Billing console: Requires root user credentials.

AWS Organizations is an AWS service that enables you to centrally manage and govern your AWS Cloud environments across multiple business units. AWS Organizations allows you to create an organization that consists of AWS accounts that you create or invite to join. You can group your accounts into organizational units (OUs) and apply service control policies (SCPs) to them. SCPs are a type of policy that specify the maximum permissions for the accounts in your organization, and can help you enforce compliance and security requirements. AWS Organizations also simplifies billing processes by enabling you to consolidate and pay for all member accounts with a single payment method. You can also use AWS Organizations to automate the creation of AWS accounts by using APIs or AWS CloudFormation templates. References: What is AWS Organizations?, Policy-Based Management - AWS Organizations
