This is one of the trickier Azure DevOps interview questions. Azure DevOps services are the cloud services of Microsoft Azure, and they offer a highly scalable and reliable hosted service that is globally available. DevOps Server, on the other hand, is an on-premise offering that is on a SQL Server backend.
Enterprises go for the on-premise offering when they want their data within their network or when there is a requirement for accessing SQL Server reporting services that are integrated with Azure DevOps data and tools.
