Hello Hariprakash Thiagarajan
There are a few ways to allow new entity users who are in the cloud to access on-premises applications that are shared between two entities.
- Azure AD Application Proxy. Azure AD Application Proxy is a feature of Azure Active Directory (Azure AD) that allows you to publish on-premises applications to the cloud. This means that users can access the on-premises applications from anywhere, as long as they have an internet connection and are authenticated to Azure AD.
- VPN. You can also set up a VPN between your on-premises network and the cloud. This will allow users to access the on-premises applications as if they were on the on-premises network.
- Remote Desktop Services. You can also use Remote Desktop Services to allow users to access the on-premises applications from the cloud. This is a good option if you need to allow users to access applications that require a lot of resources, such as graphic design applications or CAD applications.
Once you have chosen a method for allowing users to access the on-premises applications, you will need to configure the applications to allow access from the cloud. This will vary depending on the application, but most applications will have a setting that allows you to specify the IP addresses or ranges that are allowed to access the application.
You will also need to configure Azure AD to allow users to authenticate to the on-premises applications. This can be done by configuring Azure AD to trust the on-premises Active Directory domain.
Once you have configured Azure AD and the on-premises applications, users will be able to access the on-premises applications from the cloud.
Here are some additional considerations for this scenario:
- You will need to make sure that the on-premises applications are compatible with Azure AD.
- You will need to make sure that the on-premises applications are configured to allow access from the cloud.
- You will need to configure Azure AD to allow users to authenticate to the on-premises applications.
I hope this helps! Let me know if you have any other questions.
