Unlocking Scalable Data Solutions: How Cosmos DB Empowers AI, ML, and Data Science Applications
Table of contents
Cosmos DB is a globally distributed, multi-model database service offered by Microsoft Azure. It is designed to provide high availability, low latency, and scalability for applications that require real-time data processing across multiple regions. Cosmos DB supports various data models, including document, key-value, graph, and column-family, making it a versatile choice for developers working with diverse data types. Its ability to automatically scale throughput and storage, along with its comprehensive SLA guarantees, makes Cosmos DB a preferred choice for mission-critical applications.
Origins and History of Cosmos DB
Cosmos DB was first announced by Microsoft in May 2017 as an evolution of its earlier service, DocumentDB. DocumentDB was initially launched in 2014 as a NoSQL document database service. Recognizing the need for a more comprehensive solution that could handle multiple data models and provide global distribution, Microsoft rebranded and expanded DocumentDB into Cosmos DB. This transformation was driven by the growing demand for cloud-based databases that could support modern applications' scalability and performance requirements. Since its launch, Cosmos DB has continued to evolve, with Microsoft regularly adding new features and capabilities to enhance its functionality and user experience.
