It is a cloud search-as-a-service solution that delegates server and infrastructure management to Microsoft, leaving us with a ready-to-use service that we can populate with our data and then use to add search to our web or mobile application. Azure search allows us to easily add a robust search experience to our applications using a simple REST API or .NET SDK without managing search infrastructure or becoming an expert in search.
