To improve network latency issues with public internet access, what action would be most beneficial?

1. Eliminate NAT instances

2. Switch to NAT gateways

3. Increase instance types

4. Configure Route 53

The correct answer is: Switch to NAT gateways

Switching to NAT gateways is a beneficial action for improving network latency issues with public internet access because NAT gateways are designed to provide better performance and availability than traditional NAT instances. NAT gateways are managed services offered by AWS that can handle bursts of traffic more effectively and scale automatically to accommodate varying network loads. They support higher throughput and alleviate the need for users to manage the underlying infrastructure, which can introduce additional latency due to resource contention or inadequate provisioning of NAT instances. By removing the management overhead and potential bottlenecks associated with NAT instances, NAT gateways facilitate faster connections for outbound internet traffic, significantly reducing delays in accessing public services. Moreover, NAT gateways are placed in a public subnet and allow resources in a private subnet to access external internet services while maintaining security. This configuration enhances the overall efficiency of internet communications for applications running in private subnets and ensures a smoother user experience when accessing public resources. The other options either do not address network latency directly or may even introduce their own complexities. For instance, eliminating NAT instances without replacing them with another solution could completely cut off internet access for private resources. Increasing instance types might improve performance for those instances, but it does not directly address how traffic is routed to and from the internet. Configuring Route 53
