The issue described involves data loss from sensors in South Asia to EC2 instances in the us-west-2 Region, primarily due to the unreliable nature of UDP over long distances and potentially unstable internet connections. To mitigate this, two effective solutions are proposed. First, using AWS Global Accelerator (Option A) can improve the availability and performance of the application by directing traffic to the optimal AWS endpoint based on health, geography, and routing policies. This can significantly reduce packet loss by providing a more stable and faster route for the data. Second, creating a second deployment of the EC2 instances and the NLB in the ap-south-1 Region (Option C) and using an Amazon Route 53 latency routing policy can ensure that data from South Asia is routed to the nearest AWS Region, thereby reducing latency and the likelihood of data loss. This approach leverages the geographical proximity to improve data transmission reliability. Options B, D, and E do not directly address the issue of data loss over the internet. CloudFront (Option B) is more suited for caching and delivering content, not for real-time data collection. A failover routing policy (Option D) is designed for high availability rather than reducing latency or packet loss. Enhanced networking (Option E) improves network performance within AWS but does not address internet transit issues.
