Few months ago, Microsoft introduced Azure Cosmos DB, the next big leap in the evolution of DocumentDB. As a part of this release of Azure Cosmos DB, DocumentDB customers (with their data) were automatically Azure Cosmos DB customers. The transition was seamless and they now have access to a broader range of new capabilities offered by Azure Cosmos DB.
When do you know when Azure Cosmos DB is right for your project?
Refer to the 3v ( variables )
- Your data change a lot
- Your data is ingested at high speed
- You have to handle a lot of data
This where traditional DB failed and where Comos DB brings value.
When to not use Azure cosmos DB?
When you work with relational data. A more traditional solution such as Ms SQL will than fit better!
