Each Region is completely independent. Each Availability Zone is isolated, but the Availability Zones in a Region are connected through low-latency links. A Local Zone is an AWS infrastructure deployment that places select services closer to your end users. A Local Zone is an extension of a Region that is in a different location from your Region. It provides a high-bandwidth backbone to the AWS infrastructure and is ideal for latency-sensitive applications, for example machine learning.

AWS Storage Gateway is a set of hybrid cloud services that gives you on-premises access to virtually unlimited cloud storage. Customers use Storage Gateway to integrate AWS Cloud storage with existing on-site workloads so they can simplify storage management and reduce costs for key hybrid cloud storage use cases. These include moving backups to the cloud, using on-premises file shares backed by cloud storage, and providing low latency access to data in AWS for on-premises applications. To support these use cases, Storage Gateway offers four different types of gateways ?Amazon S3 File Gateway, Amazon FSx File Gateway, Tape Gateway, and Volume Gateway ?that seamlessly connect on-premises applications with cloud storage. Moving data to the cloud for advanced AWS Cloud storage capabilities and caching data locally for low-latency access gives you the best of cloud and on-premises. Applications connect to the service through a virtual machine or gateway hardware appliance using standard storage protocols, such as NFS, SMB, and iSCSI. The gateway connects to AWS storage services, such as Amazon S3, Amazon S3 Glacier, Amazon S3 Glacier Deep Archive, Amazon FSx for Windows File Server, Amazon EBS, and AWS Backup, providing storage and data management for files, volumes, snapshots, and virtual tapes in AWS. The service includes an optimized and efficient data transfer mechanism, with bandwidth management and automated network resilience, and provides a consistent management experience using the AWS Console on-premises and in the AWS Cloud.
