Edit the Trust Policy:

Go to the IAM console in the parent account and locate the role that the EC2 instance needs to assume.

Edit the trust policy of the role to ensure that it correctly allows the sts action for the role ARN in the child account.

Update the Role ARN:

Verify that the target role ARN specified in the trust policy matches the role ARN created by the CloudFormation stack in the child account.

If necessary, update the ARN to reflect the correct role in the child account.

Save and Test:

Save the updated trust policy and ensure there are no syntax errors.

Test the setup by attempting to assume the role from the EC2 instance in the child account. Verify that the instance can successfully assume the role and perform the required actions.

This ensures that the EC2 instance in the child account can assume the role in the parent account, resolving the permission issue.

Create an S3 Bucket:

Log in to the AWS Management Console and navigate to Amazon S3.

Create a new S3 bucket that will serve as the destination for the application data.

Deploy AWS Storage Gateway:

Download and deploy the AWS Storage Gateway virtual machine (VM) on your on-premises environment. This VM can be deployed on VMware ESXi, Microsoft Hyper-V, or Linux KVM.

Configure the File Gateway:

Configure the deployed Storage Gateway as a file gateway. This will enable it to present Amazon S3 buckets as SMB file shares to your on-premises applications.

Create a New File Share:

Within the Storage Gateway configuration, create a new file share that is associated with the S3 bucket you created earlier. This file share will use the SMB protocol, allowing your on-premises applications to access the S3 bucket as if it were a local SMB file share.

Copy Data to the File Gateway:

Use your preferred method (such as robocopy, rsync, or similar tools) to copy data from the on-premises storage to the newly created file gateway endpoint. This data will be stored in the S3 bucket, maintaining accessibility through SMB.

Ensure Secure and Efficient Data Transfer:

AWS Storage Gateway ensures that all data in transit is encrypted using TLS, providing secure data transfer to AWS. It also provides local caching for frequently accessed data, improving access performance for on-premises applications.

This approach allows your existing on-premises applications to continue accessing data via SMB while leveraging the scalability and durability of Amazon S3.

Create an S3 Bucket:

Navigate to Amazon S3 in the AWS Management Console and create a new S3 bucket to store the game files. Enable static website hosting on this bucket.

Upload Game Files:

Upload the 5 GB game release package to the S3 bucket. Ensure that the files are publicly accessible if required for download.

Configure Amazon Route 53:

Set up a new domain or subdomain in Amazon Route 53 and point it to the S3 bucket. This allows users to access the game files using a custom URL.

Use Amazon CloudFront:

Create a CloudFront distribution with the S3 bucket as the origin. CloudFront is a content delivery network (CDN) that caches content at edge locations worldwide, improving download performance and reducing latency for users regardless of their location.

Publish the Download URL:

Use the CloudFront distribution URL as the download link for users to access the game files. CloudFront will handle the efficient distribution and caching of the content.

This solution leverages the scalability of Amazon S3 and the performance benefits of CloudFront to provide an optimal download experience for users globally while minimizing costs.

Store the PGP Private Key:

Step 1: In the AWS Management Console, navigate to AWS Secrets Manager.

Step 2: Store the PGP private key in Secrets Manager. Ensure the key is encrypted and properly secured.

Set Up the Transfer Family Managed Workflow:

Step 1: In the AWS Transfer Family console, create a new managed workflow.

Step 2: Add a nominal step to the workflow that includes the decryption of the files. Configure this step with the PGP decryption parameters, referencing the PGP private key stored in Secrets Manager.

Step 3: Associate this workflow with the Transfer Family SFTP server, ensuring that incoming files are automatically decrypted upon receipt.

This solution ensures that the data is securely decrypted as it is transferred from the SFTP server to the S3 bucket, automating the decryption process and leveraging AWS Secrets Manager for key management.

Log Tenant ID and RCUs/WCUs:

Update the AWS Lambda functions to log the tenant ID and the number of Read Capacity Units (RCUs) and Write Capacity Units (WCUs) consumed from DynamoDB for each transaction. This data will be logged to Amazon CloudWatch Logs.

Calculate Tenant Costs:

Deploy an additional Lambda function that reads the logs from CloudWatch Logs, calculates the RCUs and WCUs used by each tenant, and then uses the AWS Cost Explorer API to retrieve the overall cost of DynamoDB usage. This function will then allocate the costs to each tenant based on their usage.

Scheduled Cost Calculation:

Create an Amazon EventBridge rule to trigger the cost calculation Lambda function at regular intervals (e.g., daily or hourly). This ensures that cost allocation is continuously updated and tenants are billed accurately based on their consumption.

This solution minimizes operational effort by automating the cost allocation process and ensuring that the company can accurately bill tenants based on their resource consumption.
