sccm 1802 help

[vipul]

I am planning to install SCCM 1802  on Azure cloud, my scenario will be like this 
install sccm management point on an Azure virtual machine ( OS will be Windows server 2016 datacenter 64 bit) 
Install SQL 2017 on Azure VM with OS windows 2016 datacenter edition 64 bit 
An SCCM distribution point on On premisses to communicate to the client.
please suggest is this right design & also suggest should we need CMG for this.
also, Certificate required for the same.

how can we suggest if it's a right design without knowing more about what you intend to do with this SCCM setup, how many clients will it manage, what type of clients, what locations, what operating systems...
