Amazon DynamoDB vs Sequelize: What are the differences?
Developers describe Amazon DynamoDB as "Fully managed NoSQL database service". All data items are stored on Solid State Drives (SSDs), and are replicated across 3 Availability Zones for high availability and durability. With DynamoDB, you can offload the administrative burden of operating and scaling a highly available distributed database cluster, while paying a low price for only what you use. On the other hand, Sequelize is detailed as "Easy-to-use multi sql dialect ORM for Node.js & io.js". Sequelize is a promise-based ORM for Node.js and io.js. It supports the dialects PostgreSQL, MySQL, MariaDB, SQLite and MSSQL and features solid transaction support, relations, read replication and more.
Amazon DynamoDB belongs to "NoSQL Database as a Service" category of the tech stack, while Sequelize can be primarily classified under "Object Relational Mapper (ORM)".
"Predictable performance and cost" is the primary reason why developers consider Amazon DynamoDB over the competitors, whereas "Good ORM for node.js" was stated as the key factor in picking Sequelize.
Sequelize is an open source tool with 18.9K GitHub stars and 2.99K GitHub forks. Here's a link to Sequelize's open source repository on GitHub.
Lyft, New Relic, and Sellsuki are some of the popular companies that use Amazon DynamoDB, whereas Sequelize is used by WebbyLab, Hostr, and Decision6. Amazon DynamoDB has a broader approval, being mentioned in 430 company stacks & 173 developers stacks; compared to Sequelize, which is listed in 38 company stacks and 33 developer stacks.

For most of the stuff we use MySQL. We just use Amazon RDS. But for some stuff we use Amazon DynamoDB. We love DynamoDB. It's amazing. We store usage data in there, for example. I think we have close to seven or eight hundred million records in there and it's scaled like you don't even notice it. You never notice any performance degradation whatsoever. It's insane, and the last time I checked we were paying $150 bucks for that.
zerotoherojs.com ’s userbase, and course details are stored in DynamoDB tables.
The good thing about AWS DynamoDB is: For the amount of traffic that I have, it is free. It is highly-scalable, it is managed by Amazon, and it is pretty fast.
It is, again, one less thing to worry about (when compared to managing your own MongoDB elsewhere).
We store customer metadata in DynamoDB. We decided to use Amazon DynamoDB because it was a fully managed, highly available solution. We didn't want to operate our own SQL server and we wanted to ensure that we built CloudRepo on high availability components so that we could pass that benefit back to our customers.
몇몇 로그는 현재 AWS DynamoDB 에 기록되고 있습니다. 개선을 통해 mongodb 로 옮길 계획을 하고 있습니다. 아주 간단한 데이터를 쌓는 용도로는 나쁘지 않습니다. 다만, 쿼리가 아주 제한적입니다. 사용하기 전에 반드시 DynamoDB 의 스펙을 확인할 필요가 있습니다.
Used it for full stack web application development, especially to interact with MySQL/ MariaDB / PostgreSQL server.
To store device health records as it allows super fast writes and range queries.
