Ah.. I think it's pretty easy for beginners and more experienced developers alike to get lost in the sea of things to know about. Azure itself is a huge collection of features and services that solve different types of problems.
As a beginner I think it's important that you understand the problem you're trying to solve first and what are the constraints you're working with. Then if the cloud is a good option for solving your problem, definitely take a look at Azure or reach out to one of us via social media.
If you're building web applications, Azure App Service is a great place to start for hosting your applications in the cloud docs.microsoft.com/en-us/azure/app-service.
If you're interesting in containers, Azure Container instances is also another interesting option to explore for getting up and running quickly docs.microsoft.com/en-us/azure/container-instances.
