We compared Amazon DynamoDB and Microsoft Azure Cosmos DB based on our user's reviews across parameters. After reading all of the collected data, you can find our conclusion below.
Amazon DynamoDB and Microsoft Azure Cosmos DB, while both providing robust cloud database solutions, exhibit distinct features tailored to diverse user needs. DynamoDB, embedded within the AWS ecosystem, excels in managed scalability, security, and high availability but faces criticism over cost predictability and the steep learning curve for new users. Azure Cosmos DB stands out with its multi-model support and global distribution, offering flexibility and performance optimization across geographically dispersed areas. However, it also presents challenges with its complex pricing structure and steep learning curve. Both platforms indicate potential areas for improvement in cost transparency and user-friendly documentation, but they also maintain solid reputations for enhancing data management through their respective unique strengths.
The summary above is based on 53 interviews we conducted recently with Amazon DynamoDB and Microsoft Azure Cosmos DB users. To access the review's full transcripts, download our report.
"Amazon DynamoDB is a fully managed service by AWS, and it is designed to provide fast and predictable performance."
"Amazon DynamoDB is powerful and fast. Its performance is good."
"Never used the support. I got all the information from the documentation."
"Amazon DynamoDB allows you to configure your read-write capacity and create a single global table that can be accessed with any other region."
"The most valuable features are the flexibility and the compatibility options without needing to use any additional services or software. It is an independent solution that doesn't need other solutions to operate."
"Stability-wise, I rate the solution a ten out of ten. I've never faced any problems."
"DynamoDB is a key-value database, and it's valuable if you have simple scan queries and don't need to do point searches."
"Storing is a valuable feature. We can store as an entire object rather than the traditional structure of the data."
"With Azure you can start small and grow as you need."
"Microsoft Azure Cosmos DB is fast, and its performance is good compared to normal SQL DB."
"The solution is highly scalable."
"From a global distribution perspective, Microsoft Azure Cosmos DB is good and easy to handle."
"Microsoft Azure Cosmos DB's most valuable feature is latency."
"One of the nice features is the ability to auto-scale"
"The best feature is the velocity to make a query."
"It works reasonably fast. You can retain the original format of the document as received by the third-party system."
"I initially faced issues with the solution's stability, performance, and security."
"If the database is kept running continuously, extra costs will be incurred. This particular area needs enhancement."
"There are some issues like if we missed something or somehow were not able to store the data, then it was quite difficult for us to get back that data."
"The pricing model should be improved"
"Querying data on the solution is quite limited, but this is like any other NoSQL database. It's the most common criticism of the NoSQL database in general."
"Having an import option, whether through browsing or local file uploads, would significantly improve the efficiency of data migration, enabling users to swiftly transfer large volumes of data into DynamoDB."
"Sometimes when we query through the UI, it takes a long time to get the results."
"They could provide more information or training programs to deliver knowledge to the engineers about the components of relational databases similar to popular vendors."
"The tool's pricing is expensive."
"Sometimes, the solution's access request takes time, which should be improved."
"Better documentation on how to integrate with other components would be helpful because I was struggling with this."
"Slight enhancements in integration interfaces, expanded dashboard functionalities, and broader use-case support would be beneficial."
"The solution cannot join two databases like Oracle or SQL Server."
"Its stability can be further improved."
"In Microsoft manufacturing, managers really need to know about the product."
"There is room for improvement in terms of stability."
