Answer:
Azure Site-to-Site VPN
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.
Answer:
Azure Site-to-Site VPN
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.
