In our last tutorial, we talked about Amazon Relational Database. Today, in this Amazon DynamoDB Tutorial, we are going to discuss what is AWS DynamoDB. Moreover, we will study the uses and benefits of DynamoDB in Amazon Web Servies.

So, let’s start the AWS DynamoDB Tutorial.

What is Amazon DynamoDB?

Amazon DynamoDB is a non-relational database service. DynamoDB is reliable and helps small as well as large firm. It offers built-in security, backup and restores, and in-memory caching.

Among the customers, the AWS DynamoDB is suitable as It is chosen for mobile, web, gaming, ad tech, Internet of Things, and many other applications that need low-latency data access.

With Amazon DynamoDB a new table can be created and the rest of the work will be handled by dynamo DB. AWS DynamoDB shows key operational metrics for the table in AWs Management Console.

This service is quite helpful along with the Amazon Cloudwatch which helps to see the throughput along with the latency of requests for each DynamoDB table.

Benefits of AWS DynamoDB

a. Automatic Management

AWS DynamoDB continuously backs up the data for the safety purpose and automatically scales the throughput up or down. DynamoDB replicates the table which helps to access data by the globally distributed application very quickly.

b. Ready for Firms

The data stored in the Amazon DynamoDB is secured with encryption and provides reliability with service level agreement. Amazon Management tools are also provided to monitor the tables, integrated monitoring tools, and support for private connections over VPN.

c. Great performance

Amazon DynamoDB delivers the consistent and quick response at any scale. The apps are also built with virtually unlimited throughput and storage. A feature of in-memory cache is provided to reduce response time from millisecond to microsecond, without any app changes.

Uses of Amazon DynamoDB

  • Used to build powerful web applications that automatically scales up and down. AWS DynamoDB also reduces the workload to maintain servers.
  • Amazon DynamoDB is used to build the mobile app which is personalized for the smooth experience. It focuses on the operational tasks so that the user can focus on different applications.
  • Devices can connect to the high-velocity, high-volume Internet of things data in Dynamo DB to Amazon Redshift and Amazon Quicksight.
  • The user can create bidding platforms and recommendation engines with the scalability, throughput, and availability of DynamoDB.
  • Flexible and reusable micro-services using AWS DynamoDB can build and for the fast performance.

Additional Data on Amazon DynamoDB

AWS DynamoDB supports key-value data structures that square measure designed to scale simply with a versatile schema. Every item (row) could a key-value try whose primary secret is the sole need attribute for things in a table and unambiguously identifies every item.

Amazon DynamoDB conjointly supports storing, querying, and change documents. By using the AWS SDK, the user can write applications that store JSON documents directly in DynamoDB tables.

Amazon DynamoDB Streams could a time-order sequence of item-level changes in any DynamoDB table.

Using DynamoDB Streams, you’ll keep track of the newest item-level amendment or get all item-level updates within the last twenty-four hours, and use the data to make inventive applications for replication, materialized views, backups, and integration with different services.

Amazon DynamoDB provides on-demand backup and restores facility for the Dynamo tables. It is also helpful for data archiving. The capacity is fro a few megabytes to hundreds of terabytes which does not impact the performance or availability of the production application.

So, this was all about AWS DynamoDB Tutorial. Hope you like our explanation.


Hence, we studied Amazon DynamoDb is helpful as it provides many benefits to the user. It provides a management console and APIs which allows the user to create, update, delete, and query tables. Moreover, AWS DynamoDB supports rich functionality with a small number of APIs.

It also uses cryptographic methods to prevent unauthorized access. This is done with the help of AWS identity and access management for fine-grained access control of users within the organization. In addition, AWS DynamoDB supports high functionality with a less number of APIs.
