Technical support is quite good, with a rating of eight out of ten.
 

Scalability Issues

8.0
Amazon DynamoDB is valued for its scalability, reliability, and efficiency, accommodating diverse data loads despite configuration challenges.
Sentiment score
7.6
MongoDB is praised for scalability and performance, though some users encounter issues with replication and complex configurations.
Scalability is the most valuable feature, and I rate it a ten out of ten.
Amazon DynamoDB is highly scalable.
In CosmoDB, the scalability is much better than with the MongoDB ReplicaSet models.
MongoDB is highly scalable.
Overall, on a scale of one to ten, I would rate MongoDB an eight; it's mostly because we're still running a monolithic environment on old hardware, so there are some limitations with read-write access.

Amazon DynamoDB is considered highly reliable, with rare stability issues and excellent scaling capabilities, despite minor configuration challenges.
Sentiment score

Room For Improvement

Users seek better documentation, query features, user interface, encryption, automation, integration, and pricing for Amazon DynamoDB.
MongoDB users seek enhanced security, scalability, transaction management, and improved documentation, while addressing cost and integration challenges.
The user interface could be improved to make it more intuitive.
We have not contracted the security options in our contract because they're too expensive; thus, we implement just encrypted databases and not the security pack.
While solutions for other databases like SQL or PostgreSQL already exist, MongoDB requires additional integrations for developing AI solutions.
 

Setup Cost

Amazon DynamoDB offers flexible, cost-effective pricing, but costs may rise with large data volumes or high traffic.
MongoDB provides cost-effective options for small businesses, though enterprise and cloud solutions may lead to higher expenses.
Amazon DynamoDB can be quite expensive due to regional differences, so I have to be careful with the pricing.
We have to pay approximately 2,000 euros per month for MongoDB.
We use the free version of MongoDB, so there are no licensing costs.

MongoDB excels in scalability and flexibility, supporting JSON storage, offering robust features, and thriving with a supportive community.
