Unlike File Gateways which are used for accessing objects, Volume Gateways present your on-premise application with the iSCSI block storage instead. Volume Gateways allow you to have point-in-time backups of your volumes stored as EBS snapshots, and come in two different operational modes: stored and cached.For Amazon FSx File Gateway, you configure file shares by attaching an existing Amazon FSx file system that contains one or more file shares, using a service account. For Volume Gateway, you create and mount volumes as iSCSI devices. For Tape Gateway, you connect your backup application to create and manage tapes.Introducing AWS Storage Gateway
To support these use cases, the service provides four different types of gateways – Tape Gateway, Amazon S3 File Gateway, Amazon FSx File Gateway, and Volume Gateway – that seamlessly connect on-premises applications to cloud storage, caching data locally for low-latency access.
What is the difference between AWS Direct Connect and AWS storage gateway : "AWS Direct Connect is a network service that provides an alternative to using the Internet to connect customer's on-premise sites to AWS" (AWS Docs). "AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage" (AWS Docs).
What is the purpose of AWS Storage Gateway
AWS Storage Gateway gives your applications on-premises and in-cloud access to virtually unlimited cloud storage. You can deploy Storage Gateway as a virtual machine (VM) within your VMware, Hyper-V, or Linux KVM virtual environment, or as an Amazon EC2 instance within your Amazon Virtual Private Cloud (Amazon VPC).
What are the names of two types of AWS Storage Gateway : Storage Gateway provides three different types of gateways: File Gateway, Volume Gateway, and Tape Gateway. For more information, including use cases, customer stories, and helpful videos, check out the AWS Storage Gateway product page.

Volume Gateway stores and manages on-premises data in Amazon S3 on your behalf and operates in either cache mode or stored mode. In the cached Volume Gateway mode, your primary data is stored in Amazon S3, while retaining your frequently accessed data locally in the cache for low latency access.
What are the 2 types of a gateway
Based on the direction of data flow, gateway in networking are of two types, such as: Unidirectional gateways: These gateways allow data to flow in only one direction. Bidirectional gateways: These gateways allow data to flow in both directions.With AWS Direct Connect, you have two types of connection:
- Dedicated connections, where a physical ethernet connection is associated with a single customer.
- Hosted connections, where a physical ethernet connection is provisioned by an AWS Direct Connect Partner and shared with you.
Direct Connect is a private link between your VPCs and on-prem that doesn't go over the internet. Transit Gateway is a kind of hub where you can join subnets together and control routing between them. So you can link up VPCs together and with on-prem via site-to-site VPNs and Direct Connect for example.
Volume Gateway – A Volume Gateway provides cloud-backed storage volumes that you can mount as Internet Small Computer System Interface (iSCSI) devices from your on-premises application servers.
What is storage volume gateway : Volume Gateway offers cloud-backed storage to your on-premises applications using industry standard iSCSI connectivity. You don't need to rewrite your on-premises applications to use cloud storage.
Can a router have 2 gateways : > Can a subnet have multiple gateways Yes, and it's normal for routed networks. However you can can only have one ACTIVE “default gateway” on most machines even though they can set a list. The first one will be used as long as it responds at ALL (to ARP requests) even if it is unable to route the packets correctly.
What are the two gateway functions
A network gateway has two functions. A LAN-to-WAN function that connects the LAN to the Internet. A WAN-to-LAN function connects the Internet to a remote LAN.
AWS Storage Gateway gives your applications on-premises and in-cloud access to virtually unlimited cloud storage. You can deploy Storage Gateway as a virtual machine (VM) within your VMware, Hyper-V, or Linux KVM virtual environment, or as an Amazon EC2 instance within your Amazon Virtual Private Cloud (Amazon VPC).Virtual Private Gateway (VGW): In cloud computing, particularly in AWS, a Virtual Private Gateway connects a VPC (Virtual Private Cloud) to an on-premises network. Customer Gateway (CGW): In the context of AWS VPNs, the Customer Gateway represents the customer's side of a VPN connection.
What is the difference between VPC gateway and transit gateway : VPC Peering and Transit Gateway are used to connect multiple VPCs. VPC Peering provides Full-mesh architecture while Transit Gateway provides hub-and-spoke architecture. Transit Gateway gives VPC connectivity at scale and simplifies VPC-to-VPC communication management over VPC Peering with a large number of VPCs.
