Azure Marketplace provides a rich catalog of thousands of products and solutions from independent software vendors (ISVs) that have been certified and optimized to run on Azure. In addition to finding and deploying ISV products, customers often use Azure Marketplace as a learning tool to discover and evaluate products. One feature in Azure Marketplace that is especially useful for learning about products is “Test Drive.”
Test Drives are ready to go environments that allow you to experience a product for free without needing an Azure subscription. An additional benefit with a Test Drive is that it is pre-provisioned - you don’t have to download, set up or configure the product and can instead spend your time on evaluating the user experience, key features, and benefits of the product.
