Microsoft Azure Cosmos DB and Amazon DynamoDB compete in the NoSQL database category. Microsoft Azure Cosmos DB has the upper hand due to its advanced multi-region functionality and integration with Azure services.
Features: Microsoft Azure Cosmos DB offers global distribution, support for multiple data models like graph and key-value store, and an auto-scale feature providing flexibility and scalability. Amazon DynamoDB focuses on speed and simplicity, offering ease of scaling from small to massive datasets with predictable performance and scalability.
Room for Improvement: Amazon DynamoDB could benefit from enhanced documentation, more efficient query capabilities, and better UI design. Microsoft Azure Cosmos DB could improve by simplifying its complex pricing model and better managing costs for high-volume operations.
Ease of Deployment and Customer Service: Amazon DynamoDB mainly operates on the public cloud with varying tech support ratings. Microsoft Azure Cosmos DB supports both public and hybrid cloud scenarios with generally well-received support, though there are occasional issues in resolving specific bugs quickly.
Pricing and ROI: Amazon DynamoDB is noted for its cost-effectiveness with a lower subscription cost and a flexible pay-as-you-go model but can be expensive for high-volume use. Microsoft Azure Cosmos DB, considered a premium solution, offers extensive capabilities but can become costly without careful management.
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.
Sometimes we cannot connect with the correct team to resolve issues.
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.
In terms of scalability, Amazon DynamoDB handles increases in data and traffic well for our team.
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 main area requiring attention is the cost aspect.
To improve Amazon DynamoDB, the challenge I faced is that you cannot essentially query with anything that you want from the table.
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.
The primary feature is constant availability without concerns about server maintenance or ensuring database uptime, as AWS manages everything from their end.
The best features Amazon DynamoDB offers are its performance and Global Tables, which stand out because of their capabilities and speed.
Scalability has significantly enhanced data retrieval speeds.
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.
