My name is Hossein Koraei and, in this article, I am trying to talk to you about the DynamoDB database briefly. Today, there is much different software suitable for various projects on the Internet, and programmers can use them to produce their projects with higher quality. One of the tools that are commonly used in all projects in the database.

Introduction of DynamoDB:

Amazon DynamoDB is a database with Key-Value structure. Note that you can use this database to enjoy millisecond performance at any scale.  Note that this database is very durable and has a lot of internal security.  In addition, this database is fully managed and there is backup, recovery, and storage of memory for any application on the Internet. DynamoDB can handle about ten trillion requests per day without any compromises and can support and respond to more than twenty million requests per second. In other words, Amazon DynamoDB is a NoSQL database service that is highly managed and provides you with fast and predictable performance seamlessly.

DynamoDB database advantage:

1- Management

This database can free software developers from the hassle of providing hardware and software, setting up and configuring databases, and managing operations on databases. Note that people can use this technology to solve the complexities of scaling and partitioning, and split your data using many more resources to fully satisfy the needs of data entry and output operations. In addition, this database automatically copies data to several available areas so that data can be retrieved in the event of a malfunction.

2- Storage scale

Amazon DynamoDB is designed to allocate resources to a table using more than hundreds or even thousands of servers distributed across multiple regions so that it can satisfy your storage and power needs without any problems.  Note that there are no predefined limits on the data that each table can store. Developers can store and retrieve any amount of data they want without any problems, and as the amount of data stored in your table grows, DynamoDB distributes the data to more servers.

3- Speed

DynamoDB can perform activities with very little delay. Because this database is built on a solid-state drive, it can lead to performance optimization even on a large scale. In addition, by not indexing all the features, the cost of reading and write operations is greatly reduced, and indexing operations are performed only for the primary keys when writing and reading data. This greatly reduces the read and write operation in general and leaves no latency in the database. Delays in this database are completely predictable. Delays remain stable even as datasets grow due to the distributed nature of the data and routing algorithms.

4. Access

Because this database is stored on Amazon servers, they copy their data in different datacenters for at least three months.  As a result, even if several servers fail or the data is corrupted, the information can be recovered without any problems and is not disturbed in any way as the activity of reading and writing code.

5. Flexibility

This type of database is a very flexible system that does not need to create a specific data model and a specific compatibility model.  Tables in this database do not have a fixed layout but instead allow the data to have a certain number of values.


DynamoDB is designed to maintain high performance predictably. In general, this database is very cost-effective for workloads of any scale from the smallest to the largest applications on the Internet-scale of this database. You can get started with Amazon DynamoDB for free. This database allows 40 million requests per month for free.
