Question

You are designing a distributed application for Azure. The application must securely integrate with on-premises servers. You need to recommend a method of enabling Internet Protocol security (IPsec)-protected connections between on-premises servers and the distributed application. What should you recommend?

Answer 1

Azure Site-to-Site VPN

Step-by-step explanation:

First of all what is a distributed application

According to Techopedia

A distributed application is software that is executed or run on multiple computers within a network. These applications interact in order to achieve a specific goal or task.

Azure distributed applications are software that run on Azure which is a cloud base technology that not only provides an Application Hosting environment, but also a full-scale Development Platform.

In order to understand why this answer for this question we need to also understand what an On-premises server is.

On-premises:

This can be defined as a computer application that is always found at a company's data center instead of running it on a hosted server or in the cloud

Now an Azure Site-to-Site VPN is the recommended method for enabling Internet Protocol security (IPsec)-protected connections between on-premises servers and the distributed application because IPsec can be used on Site-to-Site VPN, and Distributed applications can used the IPSec VPN connections to communicate.

Answer 2

Azure Site-to-Site VPN

Step-by-step explanation:

Distributed applications are computer softwares that run and work with each other on different computers that are registered under a network to execute a specific task.

And the method of enabling Internet Protocol security (IPsec)-protected connections between on-premises servers and the distributed application is a Site-to-Site VPN.

Azure Site-to-Site VPN gateway connection is used to securely integrate with on-premises servers. It is used to send encoded messages.
