A Network Load Balancer is a type of load balancer that operates at the connection level (Layer 4) and can load balance both TCP and UDP traffic1. A Network Load Balancer is suitable for scenarios where high performance and low latency are required, such as real-time multiplayer games1. A Network Load Balancer can also handle sudden and volatile traffic patterns while using a single static IP address per Availability Zone1.

To meet the requirements of the scenario, the solutions architect should use a Network Load Balancer for traffic distribution between the EC2 instances in the Auto Scaling group. The Network Load Balancer can route UDPtraffic from the client to the servers onthe appropriate port2. TheNetwork Load Balancer can also support TLS offloading for secure communications between the client and servers1.

Amazon DynamoDB is a fully managed NoSQL database service that can store and retrieve any amount of data with consistent performance and low latency3. Amazon DynamoDB on-demand is a flexible billing option that requires no capacity planning and charges only for the read and write requests that are performed on the tables3. Amazon DynamoDB on-demand is ideal forscenarios where the application traffic is unpredictable or sporadic, such as gaming applications3.

To meet the requirements of the scenario, the solutions architect should use Amazon DynamoDB on-demand for data storage. Amazon DynamoDB on-demand can store gamer scores and other non-relational data without intervention from the developers. Amazon DynamoDB on-demand can also scale automatically to handle any level of requesttraffic without affecting performance or availability3.
