What is difference between DynamoDB and MongoDB?
MongoDB is one of the most famous documents oriented database whereas DynamoDB is scalable, hosted NoSQL database service provided by Amazon with the facility to store the data in Amazon’s cloud. Mongo database offers some API for user-defined Map/Reduce methods, whereas Map Reduce is not supported in Dynamo database.
Which is cheaper DynamoDB or MongoDB?
Overall, from the above examples, the cost of DynamoDB is much cheaper than MongoDB. However, if the read and write capacity and/or the item’s size are increased, the cost of DynamoDB will be increased. MongoDB Atlas is, on the other hand, the cost stays the same until you scale up the storage needs.
Is DynamoDB a NoSQL?
Amazon DynamoDB is a fully managed, serverless, key-value NoSQL database designed to run high-performance applications at any scale. DynamoDB offers built-in security, continuous backups, automated multi-region replication, in-memory caching, and data export tools.
Why do people use DynamoDB?

Should I use MongoDB or DynamoDB?
If your business already relies on AWS services, then DynamoDB is probably the best option for you. It’ll be easy to deploy, maintain, and integrate with your current infrastructure. If, on the other hand, you’re planning on putting together a multi-cloud infrastructure, then MongoDB is definitely the way to go.
Which is better MongoDB or DynamoDB?
MongoDB stores query data in RAM which means query performance is significantly better than what you would find with Dynamo. So if speed is a concern for your app, MongoDB may be the best choice.
Is DynamoDB like MongoDB?
Both these databases support multi-document transactions, but with key differences: MongoDB supports read and writes to the same documents and fields in a single database transaction. DynamoDB lacks support for multiple operations within a single transaction.
Why is DynamoDB so expensive?
To sum up, poorly chosen partition keys, the wrong capacity mode, and overuse of scans and global secondary indexes are all causes of skyrocketing DynamoDB costs as applications scale.
How do I migrate data from MongoDB to DynamoDB?
Prepare the MongoDB cluster for migration. Create the replication server. Create the source MongoDB endpoint and the target DynamoDB endpoint. Create and start the replication tasks to migrate data between the MongoDB cluster and DynamoDB.
Is DynamoDB based on Cassandra?
Both Cassandra and DynamoDB group and distribute data based on the hashed value of the partition key. Both call these grouping partitions but they have very different definitions. In Dynamo the partition is a storage unit that has a maximum size of 10 GB. Rows with the same partition key are stored on the same node.
Can I use MongoDB with AWS?
MongoDB is an open source, NoSQL database that provides support for JSON-styled, document-oriented storage systems. AWS enables you to set up the infrastructure to support MongoDB deployment in a flexible, scalable, and cost-effective manner on the AWS Cloud.
Can I use DynamoDB for free?
AWS offers a free tier you can use to scale up your operations. For DynamoDB, the free tier provides 25 GB of storage, 25 provisioned write capacity units (WCU), and 25 provisioned read capacity units (RCU). You can use these resources for free for as long as 12 months, and reduce your monthly DynamoDB pricing.
What is difference between MongoDB and DynamoDB?
MongoDB. MongoDB is designed and developed by MongoDB Inc (it is an American Software Company).
Why MongoDB is so popular?

What are the advantages of using MongoDB?

Such model allows hierarchical relationships representation, array storage, and ability to change the records structure by simply adding or deleting fields.
