To become a Microsoft Certified DevOps Engineer Expert, first take either AZ-104 or AZ-204. Then, take AZ-400. These exams will teach you to effectively manage DevOps processes and integrations between Microsoft and the various DevOps tools. 

1) To deploy the code from Visual studio to Windows server then we should create a new VM and install MANAGEMENT SERVICE from server explorer and IIS. Install web Deploy and .net framework bundle in the VM
