MongoDB Vs DynamoDB: 10 Key Differences to make right choice

mongodb vs dynamodb

Both of the databases, MongoDB Vs DynamoDB are greatly used today by various larger platforms. They even share some similarities i.e. they are both NoSQL databases but at the same time, there are some differences that make them different from each other, and thus one gets confused in choosing the right option. Also, I’ll explain everything that is required for the reader to understand this article.

Both of the databases serve their purposes well and the users of both these databases are happy with them. I want you to follow along till the end of this article carefully in order to get to know about it in detail. I’ll try to keep things as simple as I can.

1. Understanding MongoDB Vs DynamoDB

1.1 What are databases?

In simple words, the database is an organized system for storing data in a structured and systematic form electronically either online or offline. It is controlled by a DBMS and it may use SQL(Structured querying language) for writing and querying data.

1.2 What are NoSQL databases?

NoSQL databases are those types of databases that do not have a relational type of databases management system nor do they have a predefined structure like an RDBMS. So, Having no predefined schema(structure of the database that defines how the data will be organized in it) makes it perfect for storing a large amount of data. It is very useful for bigger stores and companies for example Facebook, Instagram, and Google store terabytes of user data per day.

1.3 What is MongoDB?

MongoDB is a non-relational document-oriented database management system which is a NoSQL type of database. It means that it doesn’t rely on the relational table databases system.

Also, there is no need for predefined schemas(skeleton structure of the data in the document) while adding data to the database instead it uses JSON-like documents with dynamic schemas. Basically, the document uses key-value pairs which are the basic system of storing data in MongoDB.

1.4 What is DynamoDB?

DynamoDB is also a non-relational document-oriented database management system which is a NoSQL database. It means that it doesn’t rely only on the relational table databases system.

It stores data in the form of tables, similar to that in relational databases. It can store data in the form of key-value pairs which is also the basic system of storing data in DynamoDB.

2. What is the difference between MongoDB and DynamoDB / MongoDB VS DynamoDB?

MongoDB Vs DynamoDB

MongoDB

  • MongoDB is owned by MongoDB Inc and it is an open-source database management system.
  • It could be challenging for people to install and set up MongoDB databases because of their complexity.
  • MongoDB is good in terms of security but one has to configure it manually in order to take full use of its security features.
  • Data is stored in JSON documents in a schema-free format.
  • MongoDB allows the document size to be 400kb maximum.
  • MongoDB has a built-in data validation functionality.
  • It is best for organizations that want to use databases for multiple use cases.
  • Some of the top companies that use MongoDB include Facebook, Forbes, eBay, etc.
  • Data types used in MongoDB are int, long, date, timestamp, geospatial, floating-point, and decimal128.
  • MongoDB is much less costly but you have to make sure that your team can easily manage and work with it.

DynamoDB

  • DynamoDB is owned by Amazon.com and it is offered as a part of Amazon Web Services(AWS). Also, it is not open source rather it is an Amazon fully managed proprietary.
  • DynamoDB is way easier to install and set up.
  • DynamoDB is much more secure than MongoDB or many other databases as it can’t be accessed directly from the internet.
  • It stores data in the form of tables, similar to that in relational databases.
  • DynamoDB allows the document size to be 16MB maximum.
  • DynamoDB doesn’t have a built-in data validation functionality.
  • It is best for those who want to store data in the form of simple key-value pairs.
  • Some of the top companies that use DynamoDB include Samsung, Amazon, Netflix, etc.
  • Data types used in DynamoDB are number, string, and binary.
  • DynamoDB could be costly when additional services will be used.

3. Which is the right choice for you / MongoDB Vs DynamoDB?

Now I’ll make it even more simple for you. There are the following scenarios that you should take a look at to choose the right option:

  • If you are already on Amazon DynamoDB and it is working fine and you don’t have any issues with it, then I suggest that you should stick with it and keep on using it as it would be the best choice for you.
  • You should use DynamoDB when you are working on a highly scalable project that doesn’t require too many complex queries and most of all, you can afford the cost that it can cost you while using its different services.
  • You should go for MongoDB only when you have a highly skilled team that can easily implement and manage the database 24/7 hours or if your project uses or requires complex queries. It is also scalable and lost costly but you have to manage it yourself.

4. Conclusion

This article takes the readers from the very basic concepts like what are databases to the comprehensive definitions of MongoDB and DynamoDB along with a detailed comparison. Now that you have read the article carefully, it is an easy job for you to choose the right option out of these two.

The purpose of discussing all the related concepts is to provide you with a proper understanding of MongoDB and DynamoDB.
