Amazon DynamoDB and Microsoft Azure Cosmos DB both compete in the NoSQL database category. Based on feature assessments, Amazon DynamoDB appears to have an advantage due to its scalability and integration with AWS services, while Azure Cosmos DB shines in flexibility and global distribution.
Features: DynamoDB is recognized for its scalability and speed, which make it cost-effective for variable workloads. It integrates smoothly with AWS services and is easy to use, requiring minimal configuration to achieve optimal performance. Azure Cosmos DB is valued for its flexibility in supporting multiple APIs and data models, as well as built-in global distribution capabilities and low latency, making it highly suitable for distributed applications.
Room for Improvement: Users indicate that DynamoDB could improve its query capabilities, and find managing encryption and cross-region replication complex. Better documentation and a more intuitive user interface would increase its accessibility. For Azure Cosmos DB, users highlight the complexity of its pricing and issues with hierarchical partitioning performance. Enhancing its ability to handle large documents and providing better optimization tools could benefit users, along with improvements in security, cost management, and clearer documentation.
Ease of Deployment and Customer Service: DynamoDB provides flexibility with public and private cloud options and reliable technical support paired with extensive documentation. Azure Cosmos DB, primarily deployed on public cloud infrastructure, offers seamless integration with other Azure services. However, it could enhance customer service with more direct support and clearer documentation. Both platforms are praised for rapid response and support, though differences exist in query handling and resolution speed.
Pricing and ROI: DynamoDB's pricing is generally appealing, especially with its pay-as-you-go model suited for high-volume transactions, though it may be less cost-effective for smaller use cases. Azure Cosmos DB is often seen as expensive due to its request unit pricing model and additional costs for global distribution and availability. Despite the complexity, its scalability and ease of integration offer substantial value, particularly for enterprise agreements. Both solutions demonstrate significant ROI through reliable performance and scalability, with differing cost models.
AWS makes money from Amazon DynamoDB, and our involvement is more about professional services engagement.
Getting an MVP of that project would have taken six to eight months, but because we had an active choice of using Azure Cosmos DB and other related cloud-native services of Azure, we were able to get to an MVP stage in a matter of weeks, which is six weeks.
You can react quickly and trim down the specs, memory, RAM, storage size, etc. It can save about 20% of the costs.
When I have done comparisons or cost calculations, I have sometimes personally seen as much as 25% to 30% savings.
They follow up on support tickets until the issue is resolved.
Technical support is quite good, with a rating of eight out of ten.
Premier Support has deteriorated compared to what it used to be, especially for small to medium-sized customers like ours.
The response was quick.
I would rate customer service and support a nine out of ten.
Scalability is the most valuable feature, and I rate it a ten out of ten.
Amazon DynamoDB is highly scalable.
The system scales up capacity when needed and scales down when not in use, preventing unnecessary expenses.
We like that it can auto-scale to demand, ensuring we only pay for what we use.
We have had no issues with its ability to search through large amounts of data.
I have not faced any issues with bugs or a breakdown in Amazon DynamoDB.
We have multiple availability zones, so nothing goes down.
Azure Cosmos DB would be a good choice if you have to deploy your application in a limited time frame and you want to auto-scale the database across different applications.
I would rate it a ten out of ten in terms of availability and latency.
The user interface could be improved to make it more intuitive.
We must ensure data security remains the top priority.
You have to monitor the Request Units.
The dashboard could include more detailed RU descriptions, IOPS, and compute metrics.
Amazon DynamoDB can be quite expensive due to regional differences, so I have to be careful with the pricing.
Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective.
Cosmos DB is expensive, and the RU-based pricing model is confusing.
Cosmos DB is great compared to other databases because we can reduce the cost while doing the same things.
Scalability has significantly enhanced data retrieval speeds.
Amazon DynamoDB is a fully managed NoSQL database known for its high performance and scalability.
The most valuable feature of Microsoft Azure Cosmos DB is its real-time analytics capabilities, which allow for turnaround times in milliseconds.
Performance and security are valuable features, particularly when using Cosmos DB for MongoDB emulation and NoSQL.
The performance and scaling capabilities of Cosmos DB are excellent, allowing it to handle large workloads compared to other services such as Azure AI Search.
Amazon DynamoDB is a scalable NoSQL database valued for its speed and cost efficiency, adept in handling unstructured data and delivering fast data retrieval without predefined schemas.
Amazon DynamoDB is recognized for seamless integration with AWS services and its ability to accommodate large datasets. It provides powerful performance with automatic scaling, JSON document storage, and requires no external configurations. Users appreciate the predictable performance and ease of use, although the documentation lacks clarity, and local access necessitates third-party tools. Complex queries can be challenging due to limited API options. Desired improvements include better integration with other services and an enhanced interface. The cost structure and data storage limitations present challenges with improvements needed in backup, restore, caching, and query performance.
