Question #1319

A healthcare provider operates real-time patient monitoring systems that require immediate data processing on-premises. Which AWS service should they use to ensure the LOWEST possible latency for these applications?

A

AWS Outposts

B

Amazon EC2

C

AWS Lambda

D

AWS Fargate

Explanation

AWS Outposts (A) is designed to bring AWS compute, storage, and services to on-premises environments, ensuring ultra-low latency by processing data locally. This is essential for real-time patient monitoring systems that cannot tolerate delays caused by data traveling to/from the cloud.

Other options are incorrect because:
- Amazon EC2 (B): Runs in AWS's cloud, introducing latency due to data transfer over the network.
- AWS Lambda (C): A serverless cloud service unsuitable for on-premises processing.
- AWS Fargate (D): A cloud-based container service, also reliant on network latency.

Key Point: For on-premises applications requiring the lowest latency, AWS Outposts provides dedicated local AWS resources, avoiding cloud round-trip delays.

Answer

The correct answer is: A
