Amazon DynamoDB vs Flyway: 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, Flyway is detailed as "Database Migrations Made Easy". Easy to setup, simple to master. Flyway lets you regain control of your database migrations with pleasure and plain sql. Solves only one problem and solves it well. Flyway migrates your database, so you don't have to worry about it anymore.
Amazon DynamoDB belongs to "NoSQL Database as a Service" category of the tech stack, while Flyway can be primarily classified under "Database Tools".
Some of the features offered by Amazon DynamoDB are:
- Automated Storage Scaling – There is no limit to the amount of data you can store in a DynamoDB table, and the service automatically allocates more storage, as you store more data using the DynamoDB write APIs.
- Provisioned Throughput – When creating a table, simply specify how much request capacity you require. DynamoDB allocates dedicated resources to your table to meet your performance requirements, and automatically partitions data over a sufficient number of servers to meet your request capacity. If your throughput requirements change, simply update your table's request capacity using the AWS Management Console or the Amazon DynamoDB APIs. You are still able to achieve your prior throughput levels while scaling is underway.
- Fully Distributed, Shared Nothing Architecture – Amazon DynamoDB scales horizontally and can seamlessly scale a single table over hundreds of servers.
On the other hand, Flyway provides the following key features:
- Supported databases: Oracle, SQL Server, SQL Azure, DB2, DB2 z/OS, MySQL, MariaDB, Google Cloud SQL, PostgreSQL, Redshift, Vertica, H2, Hsql, Derby, SQLite
- Supported build tools: Maven, Gradle, Ant and SBT
- Works on: Windows, Mac OSX, Linux, Java and Android
"Predictable performance and cost" is the primary reason why developers consider Amazon DynamoDB over the competitors, whereas "Superb tool, easy to configure and use" was stated as the key factor in picking Flyway.
