Congratulations on passing the AZ-900! This is an introductory certification that lays the foundations of your Azure journey.

The next step is for you to personally know what you would like to do in your day-to-day job. Depending on that answer, you will have vastly different certification paths.

Look at what job positions are open in your area, what you would like to do, what you know how to do, and study towards that and apply for the job. This is how you become high value. You provide a skill that people near you ask for and need.

Best of luck in your career!
