You need to support the requirements for the Shipping Logic App.
What should you use?

A. Azure Active Directory Application Proxy
B. Point-to-Site (P2S) VPN connection
C. Site-to-Site (S2S) VPN connection
D. On-premises Data Gateway

Show Suggested Answer

Suggested Answer: D 🗳️
Before you can connect to on-premises data sources from Azure Logic Apps, download and install the on-premises data gateway on a local computer. The gateway works as a bridge that provides quick data transfer and encryption between data sources on premises (not in the cloud) and your logic apps.
The gateway supports BizTalk Server 2016.
Note: Microsoft have now fully incorporated the Azure BizTalk Services capabilities into Logic Apps and Azure App Service Hybrid Connections.
Logic Apps Enterprise Integration pack bring some of the enterprise B2B capabilities like AS2 and X12, EDI standards support
Scenario: The Shipping Logic app must meet the following requirements:
✑ Support the ocean transport and inland transport workflows by using a Logic App.
✑ Support industry standard protocol X12 message format for various messages including vessel content details and arrival notices.
✑ Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model.
✑ Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.

Azure VPN gateway is used to connect only to IAAS such as VM, VMSS which has a Private IP address from On-Prem to Azure. The communication is over IKE protocol. You need a Gateway in Azure as well as a VPN device in On-Prem to connect using this mode. Using On-Prem Data Gateway you can communicate to Azure SAAS and PAAS services over HTTP/HTTPS. You only need Gateway at On-Premises, no gateway is required in Azure end. So I guess the answer is correct. https://social.msdn.microsoft.com/Forums/en-US/c3ac7770-319c-4d60-8107-0a08d8da5d9e/difference-between-vpn-gateway-and-on-premise-data-gateway

I'm not convinced it's correct. Data Gateway gives access to on-prem "data sources" from Logic Apps. BUT, are "legacy apps" data sources? No. What on-prem data sources do the Logic Apps call? None. Yes, BizTalk contains a number of databases -- MsgBox, Mngmt, etc. -- but we are not running BizTalk in the cloud, so we don't need access to these data from the new Logic Apps. If we assume "legacy apps" means literally "apps", then I think they are just asking for general site-to-site access so we can call legacy apps from cloud solution, view BTS schemas, etc. as we perform the migration. I vote for site-to-site VPN.
