The AWS Cloud Development Kit (AWS CDK) and AWS CloudFormation stack output provide insights into the current deployment state. Amazon CloudWatch logs enable operational analysis and visibility into the workload. GitLab facilitates source code management, and the AWS CDK deploys changes to the AWS Cloud. Infrastructure can be re-provisioned through AWS CDK in case of failure and can be undeployed or redeployed as a unit using CloudFormation.

AWS Identity and Access Management (IAM) roles and policies, Amazon Cognito-based authentication, and an API Gateway endpoint protect and manage resources. Amazon Cognito restricts access to a specific user pool, with access tokens expiring after one hour. The API Gateway endpoint provides encrypted web API access to specific paths and services, enforcing policies and API authorization. All AWS services use IAM for authentication and authorization, leveraging IAM roles for short-term credentials.

The resilience of serverless services underpins the architecture. Lambda decouples low-level input processing from the Unreal Engine sample application's presentation layer. API Gateway throttles requests, queuing them in Amazon SQS. The Unreal Engine sample application retries failed AWS SDK operations, such as dequeuing from Amazon SQS. Standard CloudWatch logs and metrics store informational messages, error conditions, and enable notifications of errors.

Amazon CloudFront caches web page data at edge locations, scaling based on traffic. API Gateway throttling mechanisms (such as steady-state rate and burst request limits) manage API requests. For Amazon S3, edge locations (such as Transfer Acceleration) decrease latency. Adjusting provisioned throughput from Amazon Bedrock optimizes performance.

Serverless AWS services allow you to run code without provisioning or managing servers, paying only for specific on-demand usage. Costs scale according to the number of ASL translation requests, the amount of words translated into ASL in each request, and the quantity of sentence simplification operations. The serverless architecture avoids persistent AWS resources beyond S3 buckets when the overall solution is inactive. CloudFront's caching reduces requests to the web interface origin server hosted on Amazon S3. As ASL translation requests scale, Amazon SQS queues these requests as needed for later consumption.

Resource utilization scales on demand according to the number of ASL translation requests, the quantity of words translated into ASL in each request, and the amount of sentence simplification operations. The serverless architecture reduces the overall utilization and energy consumption footprint, eliminating the need to provision and manage servers or physical machines.
