Amazon ECS with AWS Fargate provides serverless container compute that can scale tasks dynamically in response to demand. This matches the unpredictable scaling requirements of a gaming workload. Aurora Serverless v2 provides on-demand, autoscaling relational database capacity while supporting complex SQL queries. EC2 with Auto Scaling (A) works but requires significant management overhead. Lambda with DynamoDB (B) is not suitable because the workload requires a relational database and long-running processes. ParallelCluster with HPC (D) is designed for batch scientific workloads, not dynamic, interactive gaming. Option C provides the correct balance of elasticity, performance, and managed services for both compute and relational database needs.

Amazon FSx for NetApp ONTAP supports Multi-AZ, providing automatic failover between Availability Zones for high availability. It exposes ONTAP LUNs over the iSCSI protocol, delivering shared block storage semantics with low latency and consistent performance to EC2 clients across AZs. This meets the requirement for “highly available” and “low-latency” block access across multiple AZs. S3/S3 File Gateway (A) is object/file, not block storage. EBS (B, D) provides block storage to a single instance in a single AZ; EBS volumes cannot be shared across instances/AZs, and host-side sync scripts add latency, complexity, and do not provide true HA. FSx for ONTAP natively provides synchronous HA pair replication, fast failover, and supports iSCSI multipathing for resilient, performant access suited to latency-sensitive trading workloads.

The requirement is to monitor network metrics such as total packet loss and round-trip time (RTT) between on-premises and AWS over Site-to-Site VPN with minimal operational overhead. AWS CloudWatch Network Monitor (formerly known as VPC Network Manager) provides a managed solution to monitor connectivity, including packet loss and latency, between AWS and on-premises networks. This solution does not require managing any additional infrastructure like EC2 instances or Lambda functions and thus reduces operational overhead significantly.

CloudWatch Network Monitor leverages AWS-managed probes and integrates natively with CloudWatch dashboards and alarms, enabling automated, centralized monitoring of network health. This aligns with the AWS Well-Architected Framework’s operational excellence pillar by minimizing manual intervention and enabling proactive detection of network issues.

Option B, C, and D involve creating custom probes with EC2, Lambda, or Batch jobs, which increases complexity, cost, and maintenance effort. They also require scheduling, script management, and additional monitoring infrastructure.

AWS Outposts brings native AWS services (including Amazon EMR) on-premises, ideal when data residency or latency constraints require local processing.

You benefit from AWS’s managed services while meeting the requirement to keep data processing local.
