If you are a student, you are eligible to get Azure for student with $100 credit. Unlike Azure free account which requires credit card, Azure for student doesn’t require credit card and the credit is valid for 1 year rather than 1 month.
You will need to have a student email address to prove that you are a student.
The only problem is that $100 credit is too little. What can you do with $100 credit as Azure is such a expensive platform?
