We performed a comparison between Amazon DocumentDB and Microsoft Azure Cosmos DB based on real PeerSpot user reviews.
Find out what your peers are saying about Microsoft, Amazon Web Services (AWS), Google and others in Managed NoSQL Databases."Its speed has had the most significant impact on our projects. For starters, we used it for its flexibility. With DocumentDB, you're not tied to a rigid structure like you are with Aurora or other relational databases. This makes it great for startups."
"Migrations are easy using this product."
"The best feature is the velocity to make a query."
"The solution is easy to use, and it is also easy to integrate with several things for database use cases."
"Microsoft Azure Cosmos DB is fast, and its performance is good compared to normal SQL DB."
"Cosmos DB is stable and easy to use."
"The most valuable features of Microsoft Azure Cosmos DB were the general infrastructure, ease to use, and interface."
"The initial setup is simple and straightforward. You can set up a Cosmos DB in a day, even configuring things like availability zones around the world."
"The biggest benefit it offers is scalability. It's easier to work with concurrency and updating data."
"It works reasonably fast. You can retain the original format of the document as received by the third-party system."
"One possible improvement could be a hybrid database solution, where parts of the application leverage a relational database alongside DocumentDB. If a system were heavily relational in nature, a database like PostgreSQL might be a good fit."
"There's a bit of a learning curve at the beginning."
"The pricing of the solution is an area with certain shortcomings."
"At this stage, we would like more enterprise support. We use MongoDB a lot, and we're trying to get rid of MongoDB. So, I would like to see more features in the Cosmos DB API for MongoDB space."
"There is room for improvement in their customer support services."
"We should have more freedom to tweak it and make our own queries for non-traditional use-cases."
"It is not as easy to use as DynamoDB."
"The tool's pricing is expensive."
"It doesn't support all databases."
"The biggest problem is the learning curve and other database services like RDS."
