EC2 Image Builder is the AWS-managed service specifically designed to automate the creation, patching, hardening, and testing of AMIs.

For this scenario, best practice is to:

Use EC2 Image Builder pipelines to generate new golden AMIs whenever features are deployed or on a schedule.

Include build components such as update-linux to automatically apply OS security patches and updates during image creation.

Deploy the new AMIs through existing Auto Scaling groups, ensuring that every newly launched instance is already patched and compliant.

This approach:

Prevents OS vulnerabilities from being introduced at deployment time.

Scales across dozens of applications because AMI pipelines are reusable and automated.

Minimizes manual effort and reduces drift between instances.

Amazon Inspector (Option A) identifies vulnerabilities but does not itself patch AMIs.

AWS Backup (Option B) is for data protection, not vulnerability management.

Patch Manager (Option C) patches running instances, but the requirement is to ensure vulnerabilities are not introduced with new AMIs; golden image pipelines with EC2 Image Builder are the recommended solution.

For latency-sensitive, globally distributed applications such as online gaming, minimizing network latency between users and application endpoints is critical. AWS Global Accelerator is designed specifically for this purpose. It uses the AWS global network and Anycast IP addresses to route user traffic to the closest healthy endpoint, reducing latency and improving performance for users worldwide.

Option C is the best solution because Global Accelerator directs traffic over the AWS backbone network instead of the public internet, which significantly reduces jitter and latency. It also provides built-in health checks and automatic failover, improving availability as the service expands globally. Importantly, Global Accelerator works seamlessly with existing Application Load Balancers, allowing the company to enhance performance without redesigning the application stack.

Option A (CloudFront) is optimized for caching static and cacheable content and is not ideal for real-time, stateful gaming traffic. Option B adds unnecessary API abstraction and additional latency. Option D introduces regional duplication and DNS-based routing, which is slower to react to network conditions and does not provide the same low-latency routing as Global Accelerator.

Therefore, C meets the requirement for global expansion with the least possible latency while maintaining a simple and highly performant architecture.

AWS Step Functions is designed to coordinate multiple AWS services into serverless workflows, handling errors, retries, and complex logic. By configuring Amazon S3 Event Notifications to trigger an Amazon EventBridge rule, you can automatically start a Step Functions workflow when a new object is uploaded to S3. Step Functions can manage retries for failed uploads and orchestrate calls to various AWS services with minimal operational effort.

AWS Documentation Extract:

“You can use Amazon EventBridge to initiate AWS Step Functions workflows in response to events from S3 buckets. Step Functions can orchestrate the sequence of AWS service calls and automatically handle retries and errors, making it ideal for automating and managing complex workflows.”

(Source: AWS Step Functions documentation, Using Step Functions with EventBridge and S3)

Other options:

A: Requires manual implementation of orchestration and error handling.

B & C: Involve additional infrastructure management and custom logic for workflow orchestration and error handling, increasing operational effort.
