Azure Cloud application (Angular/API) access on Prem windows authenticated REST API

Question

Trying to understand the communication and Authentication protocol for the cloud hosted application, accessing on prem API's.
All our API's are hosted on Prem and load balanced via F5 (Windows Authenticated)

New to Azure Cloud, what are the best practices for Authentication (Cloud ->On Prem)

API 1 has to be accessed from "Azure Cloud" as well as "on Prem" systems.

Hello @Loganathan, Murugesan - Thanks for reaching out!

You'll want to explore the Self-hosted Gateway and look to run it alongside your APIs on-prem. As for authentication, APIM supports various authentication options with OAuth being the preferred one, please review: Authentication and authorization in Azure API Management

On the architecture side of things around the REST APIs needing to be accessible to both Cloud and On-Prem apps, there are also various options available. I'd recommend reviewing the following guides:

• Use Azure API Management with microservices deployed in Azure Kubernetes Service
• The API gateway pattern versus the Direct client-to-microservice communication

I hope this helps, if you have any questions, tag me in the comments below and just let me know.
