The AWS Storage Gateway is a service connecting a software appliance with cloud-based storage to provide seamless and secure integration between an organization's EC2 instances and AWS's storage infrastructure. The service enables you to securely store data to the AWS cloud for scalable and cost-effective storage. The AWS Storage Gateway supports industry-standard storage protocols that work with your existing applications. It provides low-latency performance by maintaining frequently accessed data locally while securely storing all of your data encrypted in the Amazon Simple Storage Service (Amazon S3).
