DynamoDB: Understand The Benefits With Real Life Use Cases

Why should I choose DynamoDB for my application?

DynamoDB offers several benefits, including high performance, scalability, fine-grained access control, persistence of event stream data, time-to-live functionality, and support for storing items with inconsistent schemas.

Can DynamoDB handle automatic data management?

Yes, DynamoDB provides features for automatic data management, such as backups to the cloud, scheduled backups, and automatic deletion of expired data using Time to Live (TTL).

What are some real-life use cases of DynamoDB?

Companies like Duolingo, Hess Corporation, GE Healthcare, and Docomo rely on DynamoDB for various applications, including handling large amounts of user data, managing operational infrastructure, and storing marketing data.

What are the limitations of using DynamoDB?

The limitations of DynamoDB are it does not support complex queries or joins, it does not provide ACID transactions like traditional relational databases, and it may not be ideal for storing event data.

Building a web application is always exciting for a newbie software engineer. As a web developer, you might have started with building the frontend then backend and then you add features one by one. You choose some database for your application to store the information. Now your web application starts growing and you start getting the users for that. 100, 1000, 10000 and so on…..but what if the users will keep growing? Will it be possible that your current database can handle millions of users? If not then it can create a problem for you. You will have to migrate to another more scalable database. This is one of the reasons a software engineer has to think and consider all the case scenarios before they start building something.

A lot of web applications face scaling issues due to the growth of users along with the increasing complexity of data traffic. Business comes the need to process data faster and here comes the part of DynamoDB. DynamoDB is a NoSQL database of Amazon Web Services that supports data structures and key-valued cloud services. It is a fast, flexible, cost-effective, highly-scalable, fault-tolerant, and secure database service. You can scale from 10 to 1000 transactions per second (tps) in a couple of seconds. Now the question is what are some major benefits of using DynamoDB? How to decide that this is the right database for your application. What are some of its real-life use cases and what is the downside of using this database? Let’s discuss everything in detail.
