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.
