Azure Cosmos DB, formerly known as DocumentDB, is a globally distributed, multi-model database service designed to meet the needs of modern, highly responsive, and globally distributed applications. It offers unparalleled scalability, low-latency data access, and support for multiple data models, making it an ideal choice for cloud-native applications.
Azure Cosmos DB provides a wide range of resources to manage and store your data, including databases, collections, documents, and user-defined functions. These resources enable developers to organize and access their data efficiently while offering features like automatic indexing and global distribution, ensuring high availability and performance on a global scale.
The Azure Cosmos DB Emulator is a valuable tool for developers to replicate the Azure Cosmos DB environment locally. By using the emulator, you can create and test databases, collections, and documents without incurring any cloud service costs. This allows developers to streamline the development process and ensure that their applications work seamlessly with Azure Cosmos DB before deploying them to the cloud.
