ColdFusion and Azure Cosmos DB

Cosmos DB is a distributed database engine with a core set of features, like.

  • Ability to distribute your database globally
  • Ability to scale both storage and throughput
  • Low latency with enterprise grade security features

Cosmos DB can reshape data into formats that you may already be using. You can create a data model and then expose your model using one of many Cosmos DB API's.
