- 4. What is CosmosDB ? Azure Cosmos DB is Microsoft’s globally-distributed database service "for managing data at planet-scale" launched in May 2017. It builds upon and extends the earlier Azure DocumentDB, which was released in 2014. It is schema-less and generally classified as a NoSQL database
- 6. Advantages 1. Global distribution We can distribute data to any number of Azure regions, with the click of a button. This enables us to put our data where our users are, ensuring the lowest possible latency to customers. Using Azure Cosmos DB's multi-homing APIs, the app always knows where the nearest region is and will send requests to the nearest data center. 2 Multiple data models and popular APIs for accessing and querying data APIs for the following data models are supported with SDKs available in multiple languages: ■ DocumentDB API ■ MongoDB API ■ Table API ■ Graph (Gremlin) API ■ Additional data models coming soon
- 7. 3 Elastically scale throughput and storage on demand, worldwide ○ Easily scale database throughput at a per second granularity, and change it anytime you want. ○ Scale storage size transparently and automatically to handle any size requirements now and forever. 4 Build highly responsive and mission-critical applications ○ Azure Cosmos DB guarantees end-to-end low latency at the 99th percentile to its customers. ○ For a typical 1 KB item, Cosmos DB guarantees end-to-end latency of reads under 10 ms and indexed writes under 15 ms at the 99th percentile, within the same Azure region. The median latencies are significantly lower (under 5 ms). 5 Ensure "always on" availability ○ 99.99% availability within a single region. ○ Deploy to any number of Azure regions for higher availability. ○ Simulate a failure of one or more regions with zero-data loss guarantees.
- 8. 7 No database schema/index management ○ Stop worrying about keeping your database schema and indexes in-sync with your application’s schema. We're schema-free. ○ Azure Cosmos DB’s database engine is fully schema-agnostic – it automatically indexes all the data it ingests without requiring any schema or indexes and serves blazing fast queries. 8 Low cost of ownership ○ Five to ten times more cost effective than a non-managed solution. ○ Three times cheaper than DynamoDB(No SQL)

- 10. MongoDB/DocumentDB DocumentDb is extended from MongoDB Store data in documents DocumentDB developed by Microsoft MongoDB developed by Mongo db Inc. DocumentDB store data in JSON format while MongoDB store data in BSON
- 11. Table API in Azure Cosmo Db A key-value store, or key-value database, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, a data structure more commonly known today as a dictionary or hash. Dictionaries contain a collection of objects, or records, which in turn have many different fields within them, each containing data. These records are stored and retrieved using a key that uniquely identifies the record, and is used to quickly find the data within the database.
