What is the best option Virtual private network for my case?

Hi!

I have five small offices and in each I have a Mikrotik router. I want to create a VPN on Azure linked with these 5 Mikrotiks but I did not want to have to create 5 VPNs in Azure. Is this possible?

My objective is to create a windows service that will run on Azure and it will ping 5 Mikrotiks every 2 minutes. I will also ping other devices that will be on the internal network, and the result will be presented in a Dashboard.

I found some tutorials on the internet but they worked with one Mikrotik. In my case I will need to link multiple Mikrotiks and this number may increase over time.

My hope is that someone point the best solution for this problem.

Thank you in advance for all the help.
