+Azure Cosmos DB is Microsoft's globally distributed multi-model database service. You can quickly create and query document, key/value, and graph databases. All of which benefit from the global distribution and horizontal scale capabilities at the core of Azure Cosmos DB. 
 
 This quickstart demonstrates how to create an Azure Cosmos DB [Gremlin API](graph-introduction.md) account, database, and graph (container) using the Azure portal. You then build and run a console app built using the open-source driver [Gremlin.Net](https://tinkerpop.apache.org/docs/3.2.7/reference/#gremlin-DotNet).
