AWS IAM Roles: AWS Identity and Access Management (IAM) roles allow for permissions to be assigned to AWS resources without the use of static credentials. Roles provide temporary credentials that are automatically rotated.

Service Role: The ‘get-pics’ service role created by Rebecca includes a permission policy for read-only access to the S3 bucket and a trust policy that allows the EC2 instance to assume the role.

Temporary Credentials: When the application runs on the EC2 instance, it uses the temporary credentials provided by the role to access the S3 bucket. These credentials are dynamically provided and do not require developer management.

Developer and Admin Roles: Since the EC2 instance has the necessary permissions through the service role, the developer does not need to manage credentials. Similarly, the admin does not need to grant explicit permission to the developer because the permissions are already encapsulated within the role.

Security Best Practices: This approach adheres to AWS security best practices by avoiding the sharing of static credentials and minimizing the need for manual credential management.

Bucket Naming Guidelines: Google Cloud Storage requires that bucket names must be unique, contain only lowercase letters, numbers, dashes (-), underscores (_), and dots (.), and start and end with a number or letter1.

Valid Bucket Name: Based on these guidelines, the valid bucket name from the options provided is ‘company-storage-data’ because it only contains lowercase letters, numbers, and dashes1.

Invalid Bucket Names: The other options are invalid because:

Option B and C contain uppercase letters, which are not allowed1.

Option D contains spaces, which are also not allowed1.

AWS CloudFormation: AWS CloudFormation is a service that helps you model and set up your Amazon Web Services resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS1.

Resource Management: You create a template that describes all the AWS resources that you want (like Amazon EC2 instances or Amazon RDS DB instances), and AWS CloudFormation takes care of provisioning and configuring those resources for you1.

Complex Applications: For complex applications with multiple resources, CloudFormation allows you to manage related resources as a single unit, called a stack1.

Automation: CloudFormation automates the provisioning and updating of your infrastructure in a safe and controlled manner, with rollbacks and staged updates1.

Benefits: By using AWS CloudFormation, Steven can define his infrastructure in code and use this to create and manage his AWS resources, which simplifies the management of complex applications1.
