MongoDB vs DynamoDB

MongoDB vs DynamoDB | Complete comparison in 2022

MongoDB and Dynamo are both the most popular NO-SQL databases. This blog will make a detailed comparison of Mongodb vs Dynamodb, which helps you choose the correct database for your project. So let’s get started.

What is MongoDB

what is mongodb

Mongodb is one of the most popular No-SQL databases. It is entirely open-source, which means you can download the source code and tweak it as per your need.MongoDB is not relational and can have a dynamic schema. Dynamic schema enables you to insert the data into MongoDB without defining the schema.

You also have the flexibility to define the schema to force users to insert data having particular fields.MongoDB can handle operational, transactional, and analytical workloads easily.

MongoDB uses JSON format to represent the data and is easily scalable as per one’s requirements. You can interact with mongoDB either by command line or using an atlas.

Mongodb also has the enterprise version, which provides more features and enterprise support than open-source mongoDB.

What is DynamoDB

what is DynamoDB

DynamoDB is a fully managed enterprise No-SQL database offered by AWS(amazon web services). Mongodb is known for low latency and easy scalability features.

You can quickly get started withDynamoDB in a few hours, as you don’t have to do the entire administration work on your own. Amazon claims thatDynamoDB is very cost-effective compared to its competitors.

As per AWS, Many of the world’s fastest-growing businesses, such as Lyft, Airbnb, and Redfin, and enterprises such as Samsung, Toyota, and Capital One, depending on the scale and performance of DynamoDB, support their mission-critical workloads.

Features ofDynamoDB

The Important features ofDynamoDB are as follows:

  • Key-value storage: DynamoDB is a No-SQL database that saves the data as a key-value pair
  • Scalability: Users can start using DynamoDB with fewer nodes, and as the workload grows bigger, DynamoDB can be easily scalable as per one’s need.
  • Fully managed experience: Amazon DynamoDB gives users a fully managed database experience. Users need not have to do much to set up DynamoDB.
  • High performance: Dynamodb is designed to run a high-performance workload
  • Support high read-write requests: DynamoDB can handle petabytes of data easily and tens of millions of read and write requests per second.

Advantage ofDynamoDB

The Advantages ofDynamoDB are as follows:

  • Cost: Dynamodb is cost-effective as compared to other competitors. It charges for reading, writing, and storing your data. Users also have the flexibility to enable additional features as per their needs.
  • Security: Dynamodb is highly secure because it provides features like Threat Detection, compliance auditing, and traffic filtering. Users can also set various system notifications and reports as per their needs.
  • Easy to manage: AWS fully manages Dynamodb, and you don’t need to worry about the servers provisioning and various other administrative work related to Dynamodb
  • Replication: In Dynamodb, data is replicated to multiple zones in a region. Even if one region goes down, users can still access their data.
  • Scalability: Dynamodb can scale horizontally by adding more servers per users’ requirements.
  • TTL: Dynamodb supports TTL features, enabling users to set a specific timestamp to delete expired data from their tables. Once the timestamp expires, data will be automatically removed from the Dynamodb.
  • Access Control: Dynamodb has a robust inbuild access control system that gives table owners the freedom to grant or restrict user access as per their needs.

Disadvantage of MongoDB

Disadvantage of DynamoDB

The disadvantages ofDynamoDB are as follows:

  • The Amazon DynamoDB can only be installed on AWS and can not be installed on individual servers
  • DynamoDB does not support joins.
  • DynamoDB does not support triggers.
  • In amazon DynamoDB, there is no concept of foreign keys
  • It does not have server-side scripts
  • In DynamoDB user does not have any control over how the data is portioned.
  • DynamoDB is not suitable for relational operations.
  • Cost can sometimes go up if the user is not paying attention to resource utilization and consumption.

MongoDB vs DynamoDB

MongoDB vs DynamoDB

In this session, I will be making a detailed comparison of MongoDB vs DynamoDB.

MongoDB vs DynamoDB Performance

Both mongodb and DynamoDB are very high-performing databases. Both mongoDB andDynamoDB can be installed over the cloud and benefit from a fully managed database.

If your other middlewares are on AWS, thenDynamoDB will be the right choice for you, and go for DynamoDB; if you do not want your workload to stay on the cloud, you can also go for MongoDB.

MongoDB vs DynamoDB security

When it comes to security,DynamoDB has the edge over mongoDB.In DynamoDB, users have more features and rich IAM(incident and access management system). In the DynamoDB table, the admin can grant access to other users as per their needs.

MongoDB also supportssecurity and IAM and can be integrated with LDAP and other authentication and authorization systems. But these features are not coming out of the box in MongoDB’s open-source version.

MongoDB vs DynamoDB backup & recovery

DynamoDB offers multi-region replication out of the box as part of their AWS service offering.DynamoDB also supports on-demand and automated backup and time-to-time recovery. Users also can configure backup easily using AWS tools like ‘AWS Backup’.

MongoDB also provides continuous and on-demand backup via their enterprise product like Atlas. But to set up these backups, users need to do additional configurations. Additionally, the users are solely responsible for taking the backup on their own. They also have enterprise backup support, but users need to bear the additional costs to get these features.

MongoDB vs DynamoDB ease of use

MongoDB is more flexible than DynamoDB. You can use larger documents. More data types are available, and it’s good at working with geospatial data.

When it comes to ease of use, MongoDB has the edge over DynamoDB.Users can insert a very large document in MongoDB.

MongoDB supports many more data types as compared to DynamoDB.MongoDB does not enforce any query rate or complexity limits while querying data.

MongoDB vs DynamoDB language support

MongoDB supports almost all the major programming languages like Python, JAVA, C/C++, Perl, PHP, PowerShell, etc.

whereasDynamoDB supports fewer programming languages as compared to MongoDB

MongoDB vs DynamoDB cost

When it comes to cost, You have to spend more money on DynamoDB than on MongoDB.DynamoDB charge user based on read, write, and storage. If you have not tuned your DynamoDB properly, you might end up paying a considerable amount for managed DynamoDB.

On the other hand, users have the flexibility to set up mongodb on-premise, which will save a considerable cost over the cloud-managed database.

Which one to choose between MongoDB vs DynamoDB

MongoDB and DynamoDB are efficient and scalable NO-SQL databases that support various user requirements. However when while choosing one over another depends on your use case.

If you are using other applications in the AWS world, then it makes more sense to choose DynamoDB over mongoDB as others applications can be seamlessly integrated with it.

If you are more concerned about the security features, you can always go with DynamoDB because it provides more security configuration than MongoDB.

On the other hand, if you want a No-SQL database with complete control and flexibility, choose mongodb over DynamoDB.The other reason for choosing mongoDB over DynamoDB is that mongoDB can be deployed on any cloud vendor (Google, Azure, AWS, IBM cloud, etc.), giving you the freedom to choose your vendor and free you from any vendor locking.

When it comes to popularity, mongoDB has the edge over DynamoDB as it can be highly diverse data and gives your very optimal result while fetching data.


Finally, we have come to the end of this detailed comparison between MongoDB vs DynamoDB.I hope you like this tutorial. We have started with a brief introduction to MongoDB and DynamoDB. We also explored the advantages, disadvantages, and features of MongoDB and DynamoDB. Finally, we have compared MongoDB vs DynamoDB and explored the scenario to choose one over another.
