Cosmos DB team announced a new way named Dedicated Gateway to connect to Azure Cosmos DB. As you might know there is already a standard gateway to connect to Cosmos DB. Dedicated or Standard gateway means that there is a computer stays between Cosmos DB replica set and your application. Your application request goes to gateway server then goes to Cosmos DB database. The biggest difference between Standard Gateway and Dedicated Gateway is, you do not share the dedicated gateway server with other Cosmos DB customers.
Dedicated Gateway is totally yours and you are responsible for its costs. Depending on your application size, you can select different size of gateway servers.
Read on to learn how expensive it is and the benefits it brings.
