You understand the value of the flexibility and scalability of NoSQL databases<\/a>. The document model, using a JSON style data format, supports dynamic schemas that are easy to read\/write and fast for machines to parse. Though if you want to truly unlock the potential of the distributed nature and horizontal scalability of NoSQL databases, you should consider running those databases in the cloud. Azure Cosmos DB<\/strong><\/a> is a fully-managed NoSQL database with an API for MongoDB<\/strong>.<\/strong> It provides cost-effective pricing models, enables fast and flexible application development, and is capable of running mission critical workloads. In this post, we\u2019ll discuss how to use your existing MongoDB skills on Azure Cosmos DB.<\/p>\n

 <\/p>\n

Use Familiar Syntax and Commands<\/h2>\n

The Azure Cosmos DB API for MongoDB is based on a wire protocol implementation, which gives you the best of both worlds: leverage your skillset in MongoDB and JSON objects, while also gaining all the benefits of Azure Cosmos DB. This lets you use the libraries, drivers, and frameworks of the MongoDB you’re used to, all while capitalizing upon the performance and scalability of Azure Cosmos DB. It also means that you can build with existing data and apps because of the compatibility with MongoDB v3.6, which provides comprehensive support for MongoDB query language constructs. A detailed list of currently supported operations, operators, stages, commands, and options<\/a> can be found in documentation.<\/p>\n

The Azure Cosmos DB API for MongoDB powers production applications at Bentley Systems<\/a>, and is integral to Azure Advanced Threat Protection<\/a> and Microsoft 365<\/a>.<\/em><\/span><\/p>\n

Dev\/Test Free\u2026 then Scale<\/h2>\n

Run a workload of any size with greater control of the cost. Free Tier<\/a> (400 RU\/s and 5GB per month free) paired with Autoscale throughput<\/a> allows you to run low-cost, scalable apps on Azure Cosmos DB. Develop, test, and even deploy for free<\/a> with the capability to automatically scale up and down based on usage.<\/p>\n

Alternatively, you could leverage the new Serverless<\/a> model, the only serverless MongoDB on the market. Serverless is a cost-effective way to run small, spiky workloads. With this consumption-based model, you are charged for the Request Units (RU) used by your requests and the storage consumed by your data. This means that there\u2019s no minimum cost when using serverless \u2013 you only pay for what you use.<\/p>\n

Pick the right model for your workload<\/em><\/p>\n
