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."Migrations are easy using this product."
"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."
"The solution is easy to use, and it is also easy to integrate with several things for database use cases."
"The graphical representation of data is the most valuable feature of the solution."
"From a global distribution perspective, Microsoft Azure Cosmos DB is good and easy to handle."
"Its wide support to the ecosystem is valuable. We can use this database with a lot of use cases, and that's one of the reasons why we prefer it. We have a lot of vendors, databases, and use cases, and wherever possible, we are trying to standardize databases. It is also secure."
"Cosmos DB is stable and easy to use."
"Microsoft Azure Cosmos DB is fast, and its performance is good compared to normal SQL DB."
"With Azure you can start small and grow as you need."
"It is non-SQL and helps to manage and manipulate data from the coding, rather than direct data and complex queries."
"There's a bit of a learning curve at the beginning."
"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."
"It's still new, and good training resources are harder to find. Even the most recent books on Cosmos DB are several years old, which is ancient in IT terms."
"The API compatibility has room for improvement, particularly integration with MongoDB. You have to connect to a specific flavor of MongoDB. We'd also like a richer query capability in line with the latest Mongo features. That is one thing on our wish list. The current version is good enough for our use case, but it could be improved."
"I hope they improve the service. Before last year, improvements on Cosmos DB were very slow."
"The biggest problem is the learning curve and other database services like RDS."
"A further simple application is required for Brazil."
"It would be ideal if we could integrate Cosmos DB with our Databricks. At this point, that's not possible."
"The built-in integration of the solution is tight."
"I have been a devoted Microsoft fan, but Redis DB's memory caching capabilities are really making progress. Even if Cosmos DB is continuously improving and is quite advanced in the field of internal memory optimization, I would still recommend Redis DB to a customer."
