Is DynamoDB actually 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.

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.

Should you use DynamoDB or 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.

Is DynamoDB compatible with MongoDB?

Introducing Amazon DocumentDB (with MongoDB compatibility) Today we are launching Amazon DocumentDB (with MongoDB compatibility), a fast, scalable, and highly available document database that is designed to be compatible with your existing MongoDB applications and tools.

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.

Is DynamoDB query expensive?

Scans and Queries are Expensive! Scanning and querying DynamoDB tables counts against your provisioned read capacity, meaning costs are relative to the size of the number of items being scanned – not the number of results being returned. This can get quite expensive if you need to query your data frequently.

Can DynamoDB replace MongoDB?

Because Amazon DynamoDB supports both document and key-value data structures, moving a MongoDB JSON document is relatively simple….Performing a Live Migration from a MongoDB Cluster to Amazon DynamoDB.

MongoDB	DynamoDB
Single field	Partition key/global secondary index

Is DynamoDB no SQL?

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.

Is DynamoDB NoSQL?

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.

What is the difference between DynamoDB and MongoDB?

In conclusion, DynamoDB and MongoDB are both good choices for NoSQL databases. Both can provide business needs. DynamoDB starts with lower cost. Easy setup and maintenance on security and tables. MongoDB provides more features such as data validation, indexing strategy, query operation, and more data types. But it also costs more to start.

Is MongoDB available in the cloud?

As mentioned above, MongoDB is also available as a fully managed cloud database with MongoDB Atlas; this model is most similar to how DynamoDB is delivered. In contrast, DynamoDB is a proprietary database only available on Amazon Web Services.

Is DynamoDB available on a local machine?

In contrast, DynamoDB is a proprietary database only available on Amazon Web Services. While a downloadable version of the database is available for prototyping on a local machine, the database can only be run in production in AWS.

How to migrate data from MongoDB to DynamoDB using AWS DMS?

To migrate a sharded collection from a sharded cluster, you need to migrate each shard separately. In our approach, we perform migration of each shard separately to a single DynamoDB table using one AWS DMS task per shard. Following are the high-level tasks involved in migrating data from a MongoDB sharded cluster to DynamoDB using AWS DMS:
