The salary offered for an Azure Solution Architect depends on two factors:-
1. The company you are working for.
2. Experience you have.
Talking about companies like MIcrosoft, they pay something around 17L - 38L per year for the post of Azure Solution Architect. Startup companies or service based companies pay something around 5L - 23L per year for the same post.
Fresher, they are generally hired for the Azure Solution Architect and they get paid the salary of 5L - 17L per year. Whereas, people having experience can easy bag a salary of 15L - 38L per year.
Hope this helps.
