Explanation

AWS Storage Gateway acts as a bridge between on-premises environments and AWS Cloud storage, giving local applications low-latency access to cloud-stored data by caching frequently used data locally. It seamlessly integrates on-premises infrastructure with AWS storage services like S3, EBS, and Glacier, making it ideal for hybrid cloud scenarios.

Why the others are wrong:

• Amazon CloudFront (A) is a Content Delivery Network (CDN) designed to cache and deliver web content to end users globally - not for connecting on-premises applications to cloud storage.
• AWS Backup (C) is a centralized backup service for automating and managing backups across AWS services - it doesn't provide on-premises application access to cloud data.
• AWS DataSync (D) is used for transferring/migrating large amounts of data between on-premises and AWS, but it's a one-time or scheduled data movement tool, not a continuous low-latency access solution.

Memory Tip: Think of Storage Gateway as a "gateway" - just like a physical gateway connects two locations, it connects your on-premises world to AWS Cloud storage, acting as a local cache to ensure fast, low-latency access. If the question mentions on-premises + low-latency + cloud storage, Storage Gateway is your answer.
